How to: 240sx Intake Swap

[JsD21HB]

(Swap pertains to HB only) This is NOT for the ka24de found in frontiers. (dont have specifics if it is able to be done on a 95+ HB.)
I am finaly done with the 240sx intake install.
After getting lots of wrong info here is the stuff that is true.

http://i141.photobucket.com/albums/r66/jsd21hb/240sx071.jpg

What you will need:
240sx intake manifold and ALL sensors inculding MAF
Both 240sx and Truck wiring diagrams,vacumm diagrams, and pin voltage
chart.
12mm wrench
12mm socket and socket wrench
14mm socket
Soldering iron
Solder
About 4' 14awg wire
2' of 1/2" heater hose
2, 1/2" x 1/2" hose barbs
90* 2 1/2" peice of pipe
Flat plade screwdriver
About 4' of 3/8" heater hose(for the TB)
5/32" vacumm lhose
2' of 3/8" high pressure fuel hose
Asstorted hose clamps

Removing truck intake manifold:
1.) Remove all the intake shit
2.) Drain antifreeze
3.) Remove heater hoses from heater core.
4.) Start unpluging connectors for the Mass air flow, idle air control valve, Coolant temp,Air temp sensor,Injectors,and Crank shaft sensor or dizzy.
5.) Move half of harness out of way
6.) Remove upper radiator hose
7.) Disconnect Fuel lines
8.) Take out the 7 bolts and nuts that hold the manifold to the head.
Also remove the 2 lower mounting bolts.
9.) Either cut or remove the egr tube from the exhust manifold
10.) Remove the two bolts to the egr valve and remove it's vacumm hose
11.) There is a bolt holding the engine harness snugly to the manifold you are going to have
to remove that bolt as well
(A/T only remove the SCV contoll solenoid bracet from manifold in order to free kickdown
cable.)
Should look something like this.

10.) Remove manifold without damaging the head(Prying with a screwdriver helped me.)

Installing 240sx intake

1.) Take your thourougly cleaned and egr blocked intake manifold and place it onto the head.
2.) Tighten the bolts in torque sequence.
3.) Install the 240sx injectors into the 240sx fuel rail and install rail on the manifold useing new
o-rings and seals with taking care not to rip them upon install.

4.) Cut Idle Air Controll valve harness of the truck before the IACV, FICD and connector.

http://i141.photobucket.com/albums/r66/jsd21hb/Picture-004.jpg

5.) Solder the spare injector connectors to truck connector extend the leads about 18"s.

6.) After soldering connect the coresponding connectors to the IACV and the FICD. and hit ( Bang out the firewall in the corresponding location so the the two dont hit the firewall making it impossible to connect the ficd)
7.) Hook up heater hoses to TB and to the heater core.
8.) Crack P/S line loose and move it into position and tighent down out of the way of the manifold and
where intake pipeing is gonna be.
http://i141.photobucket.com/albums/r66/jsd21hb/Picture-007.jpg
9.) Hook up intake piping and connect the MAF. I am pretty sure you can use the truck MAF if you
are carful and pay attention to how close the hot wires are to the inside of the case and use a washer
to space it out. But use the 240sx MAF it is a hell of alot easier.( When i first fitted the truck
MAF inside the 240sx housing I didn't realise that the hot wire extensions where touching the inside
of the case and grounding out.)
10.) Start pluging the injectors, MAF, IACV, TPS, SCV, and CPS in.
IMPORTANT: MAF PINS A=12v posititve (Black w/white) B=Ground (White) C=Signal (Black)
13.) Hook up electrical connection to the Air regulator with an
injector clip and run the wires to a KOER power source
(i.e. fuel pump relay like the 240sx wiring diagram specifies.)
12.) Hook heater hoses back up and the fuel lines back up.
13.) Route vacumm lines to the Carbon Canister and the FPR.
also if you left SCV then also hook up the vacumm solenoid
and vacumm canister.
14.) Drill 2 holes in the 90* bend and thread in the two hose barbs for the Valve cover vent and the IACV tubes.
(Make sure both are securely fastend with hose clamps dont want any vacumm leakes.)
15.) Fire it up. Your done. (you might have to adjust the idle screw.)

That is it.... If i doesn't run than you did something wrong....
P.M. me if you need help or just post a topic and i'll help.

[slammed97]

could u explain the sensor abreviations and where they are on the truck intake and the 240 intake....im totally lost on those...i have a motor that already has the intake swap done but im gonna have to do the plumbing and woring when i put the motor in the truck....

[JsD21HB]

it really needs to be redone but i fixed what i could pics are not really as good as they ought to be so please if u need specifics feel free to send a pm or post a ?.

[thatboi_j]

Can you e-mail me a better photo of where you had to beat in the firewall? miserjw@ddg83.navy.mil

[thatboi_j]

Also what is the KOER power source?

[JsD21HB]

Key on engine Running or on what ever u wanna call it.

[thatboi_j]

where did you connect yours?

[JsD21HB]

uummmmm.....
i cant remember right off hand. but the fuel pump relay will work or u can also use the windshield wiper motor's power. or any other thing that is easily accesable and it could also be just a key on power source.

[Asphalt Assassin]

when you swap out the intake do you have to use the 240 injectores or will the old ones work also ?

[JsD21HB]

when you swap out the intake do you have to use the 240 injectores or will the old ones work also ?

ur stock hb injectors will work. for a short while there i was using 2 of my truck injectors and 2 240 injectors. seemed to run ok.

[nismopu]

ur stock hb injectors will work. for a short while there i was using 2 of my truck injectors and 2 240 injectors. seemed to run ok.
depends on the year of your truck though, 95-up sidefeeds arent going to work with the 240 intake. peace.

[Dr.No1]

Do you have to put the Truck MAF inside the 240sx Maf housing or can you simply use the complete 240sx maf and just splice the pig tail to truck pig tail?

[JsD21HB]

i used the complete 240 maf. when i tried to put my truck maf in the 240 housing it was grouning out to the housing on the inside. its kinda hard to explain but i would rather use the 240 one.

[nis720]

Not sure if you cleared it up in this thread.... but what ECU did you use? stock truck ECU or a 240sx ECU?

[91nissan94]

nis. I just used the truck ecu. what did you end up using?

[JsD21HB]

had the truck one for a little while but it was acting funny think it started to take a shit so i swaped in an #11 240 ecu seems fine now, only thing i could never figure out was my damn tach with this ecu.

[nis720]

nis. I just used the truck ecu. what did you end up using?

I ended up with a 240sx Auto ECU... I have a few extra 240sx ECU's but the 5 speed ECU's seem to cut off in 5th gear. But I don't have the 5th gear sensor hooked up.

[Asphalt Assassin]

i got to hear mine running half assed yesterday..... it's ok when you just let it idle but when you give it gas it dies..... any thought on why ?

also in the pic below there is a metal tub that runs around the side of the top intake... and a valve is hooked to it... i think it goes into the side of the intake tube can i take that off and just run that valve into the back side of the intake...

http://i143.photobucket.com/albums/r138/bodydropped26/DSC02699.jpg

[Asphalt Assassin]

here's a better pic it's right below the pvc valve



http://i143.photobucket.com/albums/r138/bodydropped26/DSC02702.jpg

[91nissan94]

what I did with mine was disconnect the hose from the air control valve that you don't have connected right under the pvc valve. I bought a cap and some hose and used the cap to block off the valve and used the hose to route from the metal tube to the valve cover vent. I will get a picture I you need one.

[JsD21HB]

is that how u were running it whit the tb just open like that? No maf?

[VG30E]

i am suprised it ran at all with MAF. Mine won't.

[JsD21HB]

yeah i think thats ur problem right there. no maf.
try hooking all that shit up and then get back to us.

[Asphalt Assassin]

yeah i think thats ur problem right there. no maf.
try hooking all that shit up and then get back to us.

everything was hooked up i had a friend holding the maf sensor (from the truck ) in front of the intake for air flow..... i cannot find a maf off of a 240sx the only one i could find around here is off of a 96 i believe the plugs are different of course but i cut the connector off of the car you guys think that would work if i splice it in....

right now i start it up it runs about 20 seconds and shuts off....

[91nissan94]

all you need to do is tee it off at the split in the metal line. I will take a pic tomorrow so you can see. did you adjust the idle control to get it to run good?
also check out ka-t.org got my maf from there for 20 bucks.

yeah get the pic that would help.... also i have been over there on ka-t
i tried to buy one but the guy still hasn't sent it yet and is giving me the run around... i went to a junk yard and found one off of a 96 and the plugs are different but same wires ( color wise) you think it would work..

[91nissan94]

here is the link to the pics http://www.infamousnissan.com/forum/album.php?albumid=256
as far as the maf, I'm not positive if it will work, if you wire it up right it probably would. maybe ask at ka-t, not to familiar with the dohc's. if you need anything else let me know.

[JsD21HB]

i dont belive that the dohc maf will work. i think i have a spare. pm me and ill check

[Asphalt Assassin]

well , i had cut the connector off of the car, so last night i stripped the wires back and pluged them in to the factory connector put it in line to the intake fired it up, and it ran just fine i could rev it up and all but it's loppin like a 350 i think i just need to fine tune it now...
thanks so much guys you all have helped me out big time...
i'll get pics up as soon as i can..

[ridin4life]

i got a ? i didnt see answered. i got a 96 hb with obd2 can i do this swap (i have all the parts lying around) without get a cel light come up or will it come up

[JsD21HB]

i will more than likly trigger a check engine light but i might not if u use the egr and all that good stuff. only way to know is to do it.

[tropicilluzion]

i need ur help i did the swap on 95 hb it start and idles but i cant rev it it will cut/bog out. the only way it'll rev up is if i slowly give throttle need help bad

[thatboi_j]

Could be something with your MAF sensor. I never got around to doing the swap...so I'm not 100% sure. But my Altima did the same thing and the dealership replaced the MAF sensor and it works fine now. So check your wiring connections first since that's a free thing! lol

[JsD21HB]

def the maf or a mis-aligned tps sensor. time to whip out the volt meter.

[tropicilluzion]

could try ka-t.org
tropic didn't think about the maf, which one are you using?
using the one from a nissan pathfinder v-6
:confused:

[JsD21HB]

that might be why. oh u could use it if u tuned ecu and adjusted ur "k" value for the new maf, ec

[Motorhead]

troic illusion let us kno if that works out. isnt your truck obdII?

[cooder]

hirt me up if its possile 4 the 240 sx intake will fit a 96 hb cuz i want 2 do that 2 my trk plus a turbo install

[Ratrod25]

I dono if i missed it but do you need the 240 wire harness? or just the sensors?

[tat]

hey do i need the upper and lower intake manifold if i am going to do this

[dahk16]

I dono if i missed it but do you need the 240 wire harness? or just the sensors?

yes, i'm also wondering about this myself. *bump*

[91nissan94]

just the sensors, you just move the truck wiring to fit the manifold.

[Nismo Dave]

Hi just swaspped a 240sx motor into my 93 hardbody. My question is the two sensors on the back of the intake and the one on the side of the intake by the fuel rail do i have to have these sensors?

[91nissan94]

if you are talking about the iac on the back of the intake then yes. not sure which one you are talking about. a pic might help.

[nis720]

Hi just swaspped a 240sx motor into my 93 hardbody. My question is the two sensors on the back of the intake and the one on the side of the intake by the fuel rail do i have to have these sensors?

They regulate the iddle.... some people have done away with them and say it mostly affects cold starts.

[nis720]

I dono if i missed it but do you need the 240 wire harness? or just the sensors?

If you're truck has a KA already in it.. you only need to extend certain wires.

If you're truck does not have a KA in it.... it's easier to wire a 240sx harness into your existing harness because the 240sx harness is seperate from the chassis wiring. I gutted my 720 harness of all the Z24 wiring and left the lights and misc stuff.

[Nismo Dave]

They regulate the iddle.... some people have done away with them and say it mostly affects cold starts.

Thx had it fired up last night just have to finish the cai this morning and should be driving my Hardbody again this evening.:thumb:

[1lomofo]

whats the benifit to all of this? do you feel a difference??

[JsD21HB]

u gain up top power. makes boosting alot easier.

[1lomofo]

:) all i needed to hear!

[dahk16]

so as far as sensors go, what are ALL the sensors i need to do this? i wanna start buyin these things so i can get started sometime soon. i know i need the fuel rail, maf, injectors, and throttle body. what else? please and thank you.

[JsD21HB]

throttle body comes on the manifold. the tps usually comes with the manifold. so u need.
maf
injectors
fuel rail
tps
iacv
all of that shit usually comes on the manifold. u use all of the 240sx stuff.

[dahk16]

ok. thanks. my manifold came with nothing. so i hafta go dig up everything which iswhy i ask.

[hbdrifter]

so how would i do this swap if i have a automatic. do you need to hook up the kick down cable or what???????

[91nissan94]

yes you would want to do that if you want your passing gear to work.

[JsD21HB]

^^^ actually it controlls more than just the passing gear belive it or not if left disconnected ur trans will shift through all gears by 20mph and u it will not down shift when coming to a stop it will start out in OD. i made this mistake when i did mine and made up some extra cable and guides and connected it to my throttle.

[hbdrifter]

ok i was planning on do this swap i have everything but the cable caught my mind ill have to rig up something like you did till i convert it to manual then it wont matter.

[hbdrifter]

ok so i have all the intake on got my intake made up, modified the 240sx maf to accept the truck maf, have the tps hooked up but the plug that has 2 small black wires, and two bigger wires that are black and red, i dont know what to wire those to. also how do i wire up the air regulator the wiring on this thred isnt very good. it runs and everything but pops and back fires. if anyone could lead me to wiring those sensors on the back of the intake that would be great.

[wiredxchange]

Did Tropic Illuzion resolve the MAF problem?
I have a 97 Auto and want to do the same thing so I can add a little boost 5-8psi

[JsD21HB]

http://i141.photobucket.com/albums/r66/jsd21hb/valve002-1-1.jpg
and i would also recommend using the whole 240sx maf. and use the pin out for the maf on the first page.
yeah i did this along time ago on the other forum it should really be redone.

[hbdrifter]

i actually tossed that part out its only used on coldstarts. i found out y its was running so bad though. i had put my oil pump shaft in a tooth off so thetiming was way off.

[jimmy726]

Ok so ive looked thru this whole thread and couldnt find it. What years can you use the 240 intake???? Just all the years with a ka24e

[david29]

Jimmy,
I believe its the 89-90 240 SX. It has to be the KA24E engine, NOT the KA24DE.

[91nissan94]

yep 89 and 90 240's are what you are looking for.

[93hb4me]

93 hardbody 240 engine and tranny

first of all gotta say wat up pimps and theres alot of people dat have already done this and hoping to get some help from yall plz!!!!

I started off wit blown head gasket on my ka Looking into sr20/ka24de swap. When my head gasket went had to go wit this motor due to time, cudnt be witout truck 4 long ....Anyway paid 300 bucks 4 motor and have almost got it installd as far as mounted. Ran into clearnce issues resolved it wit a big hammer. i am using an engine and tranny out of a 240sx on my truck. at this point im conecting the trans mount but i gota custumize it to fit (im 3 days into this project by the way) but the brackets to motor are from da 240 motor wit truck mounts and its bolted in.im starting to get excited but kno its to early for dat. now when it comes to da wiring dats where im gona need help. but a custum trans mount and maybe a custum drive line and i hope dat part will be done. has anyone done this before ?
In order to do this swap ive pulled out my bench seat and am planing to get bucket seats ( 240 trans is 5 1/2 inches longer which means shifter sits back further and on the ground). No wholes have been cut to fit shifter.

At thiis point im gona need but not shure :
maf
new seals 4 injectors
speedometor cable
240 shifter
looking 4 answers to get my truck on the road in 2 weeks if possible wit ur help

[91nissan94]

long over due update on this swap. I finally got around to putting in the cam that I got when I got my intake manifold and I recommend that this be done too. I think the cam is matched better to the intake. been driving it for a few days and happy with the results. some will say that the cams are the same but I don't believe this.
disclaimer: I have not measured these cams against one another. I have read where the specs were different, but there has been much debate. I feel that they are different, especially in the mid to upper rpm range. would I do this again? yes, and this was my first time changing a cam.
result: worth it to me. smoother powerband and seems to use less effort at highway speeds.

[dahk16]

now do you mean a 240sx cam?

[91nissan94]

yes the 240 cam.

[pejsa HB]

did the throttle cable need any modification? or did you pull the one from the s13?

[91nissan94]

I used the truck throttle cable on my swap. will get some updated pics in the next couple of days.

yes someone does need to update it. i did this when i was 17. Needs way more pics and more detailed info for sure.

[L-Rolla]

do u need the lower manifold to do this swap aswell?

and will the injector rail and injectors form a dohc work on a sohc?

[91nissan94]

you need the upper, lower, all heater hose and vacuum tubes(the metal ones), the manifold to block bracket, tps, and the 240 maf and holder. you can use the truck injectors and rail. the rest is just install and route things where they need to go. my best advice to anyone who wants to do this is get a copy of both fsm's and compare the two. if you can delete emissions then I would as it makes this alot easier.

[93hb4me]

just got my truck out of exhaust shop my truck is running great motor feels like completly different motor tx for your help

[driftin_360]

just got a complete 240sx motor out of an 1989. kinda been wantin to swap the intake off the 240sx engine. cause its easyer to turbo or put a CAI. just lookin at a few plugs with different ends? could use sum help
thanks Ryan

[intenseconcepts]

hey i want to do this swap on a 2000 frontier... i know everybody says that u need an intake from a 96-up 240sx but i came across one from an early-90's one for real cheap... is there any way i can make it work??

[91nissan94]

it would be way more trouble than it is worth to make it work. go with the 96 up setup

[intenseconcepts]

well i ended up getting one for $20... if i can't use it then i'll just get rid of it.. but if there's any way to make it work i'd like to, it looks about the same as the newer one, what specifically is different?

[91nissan94]

odb1 vs odb2. alot of sensors aren't on the older intake that you will need to run.

[hater]

Anybody know about a 97 truck automatic have alot of parts just need comfirmation that it will work.

[WRLiv]

ive been doin a little research on this swap and was hopin someone could help me out abit. im pretty sure i know y this is done, more torque and power for a turbo? couldnt u just put a 240 engine in ur HB instead of doing all of this, and then put a turbo on the 240 engine? is there something the trucks Ka has that the 240s doesnt? Or is it just because an engine swap involves more work than swaping these parts?

[91nissan94]

the reason you just use the intake on the truck motor is you have to mod the pan and oil sump to use the 240 motor. way easier to swap the intake mani's. the trips to the parts store for all the little things is the worst part.

[tattooeddude]

maybe i missed something in one part it said just extend some sensor wires then in another part it said the MAF needs to be repined so which is it? repined or extended? or just use the truck MAF in the 240 housing? What year 240 do i need to look for is it just 89-90 or will a 93-94 work on a 95 hb

[m13hty]

ok is it just the 89-90 sohc engine intakes that will work?
or will any sohc 240sx intake work? cause there are a couple at the upullit down the road i can get for cheap as hell. just need to make sure that i can use any year sohc intake on my 1997* hardbody.
i think the 89-94 240sx came with the sohc. altho some of the later 93s and 94s had dual. not for certain on that. but i believe my 240 i had was a 91 or 93 and i know it was sohc. thanks in advance!

You need to get the 89-90 intake out of the 240SX. These years are the only ones I know people are swapping over to the HB's.

sohc ka's only came in USDM 240sx's from 89-90.
91-98 they had a DOHC ka.
95-98 same motor but having slight changes from the 91-94.


Im making a thread soon on this, since this needs to be re written badly.

[rossfi215]

Ok so just read this entire thread, and this is what I got. I have a 93 hardbody with the ka24e motor, and I got a complete motor and trans, ecu, wiring harness, everything out of a 1990 240sx, both are automatics, now my question is can I just pull my old motor out and drop the 240 motor in and then just extend the wires to make it where the plugs will reach, and what's the difference on the oil pans or is there a difference between them, any help will be much appreciated thanks.

[datzun90]

I ended up with a 240sx Auto ECU... I have a few extra 240sx ECU's but the 5 speed ECU's seem to cut off in 5th gear. But I don't have the 5th gear sensor hooked up.

Did you have the same problem with the tach not working. I have two truck ECUs and an Auto 240 ecu and I would still like to use my tach. Thanks

[RedAggie03]

What are you guys paying for these intakes? I've found a 90 240sx that is being parted out and can get the complete intake, sensors, and all. I feel like I should jump on it, but not sure what I should pay.

[sicnis]

i just got an 89 240 motor for 100bucks, the guy wanted 200

doin some research on adding a t to my now ka and came across this, will answer this question stated above with hard numbers.

[slyderdai]

What are the benefits of doing a manifold swap? Are they that different to see a benefit worth all that that work and headache?

[spack]

for me its gonna make the turbo setup wayyyy easier. also the 240 is built for better top end power, better air and exhaust management, where the d21 is more for low end tq where it doesn't really matter how efficient the air is transferred to the cylinder. if you can swap the intake (more efficient air flow) and the cam (larger durations and lifts) then you will gain a noticeable difference from stock. in the chevy world it would be like doing a 305 to 350 swap. same everything just about but just a larger bore.

[slyderdai]

so wouldn't a simple port and polish of the intake be just as beneficial without all of the headaches? or a custom fabbed mani?

[david29]

This wouldnt hurt to go along with the addition to the 240SX intake. Doesnt replace it though. I dont think.

i did this swap and have an extra connector coming of the front of the harness. It is coming out of the wire loom that heads over to the distributor what is that connector to? I have looked for where it could go and cant find it. It is a black connector. Thanks in advance.

[spack]

i guess you could fab one up but you will still atleast need the sohc mani to build from and even if you do the work yourself the price of materials will be more that a good junkyard or craigslist find will cost.

and the SOHC is the one youll need, the dohc im pretty sure has different bolting surfaces.

and if you get a full donor car to rape pull the cam and swap yours. it will bring the full potential of the intake.

[anotherprojectcar]

What is the benefit to this conversion if any?

[pejsa HB]

i notice more tq and hp not alot but noticable for sure.

easier to work on and get parts for.

its worth it

[The Cisco Kid]

sorry if i missed it but are you saying it is not possible to this to a ka24de frontier if you use a later model 240sx manifold>>?

[pejsa HB]

yes you can!!!

dual cam stuff is interchangable only to dual cams

and the same goes for single cams.

[4DRZ]

So with the Frontier, mine is a 2000, I would need a 1995-1998 240SX intake manifold, correct? Thanks for the help by the way...yes you can!!!

dual cam stuff is interchangable only to dual cams

and the same goes for single cams.

[pejsa HB]

you are right, and your welcome

[4DRZ]

Sorry for the dumb and dumber questions, but I need the NA version correct, because I cant use the one from the 240SX with the KA24det? They look a lil different. Only asking because I am trying to buy one now. Are there any pics of the correct one you can point me to so that I dont buy the wrong one?

This the correct one? It states that its from a 1995 NA 240SX

[schmauster920]

to 96 you use the 89-90 240sx sohc manifold
97+ the 91-98 intake will bolt up.. OBD1, 2 and other differences

[4DRZ]

Yeah I figured it out. Ive already bead blasted it and am preparing it for powdercoating. :)to 96 you use the 89-90 240sx sohc manifold
97+ the 91-98 intake will bolt up.. OBD1, 2 and other differences

[Roadkill1260]

thanks so much for this thread, just did a 92 ka swap from a NAPZ, was looking into the intake swap but heard you HAD to run a 240 partial harness, apparently i dont, thanks alot.
1 question, did you MPG drop when you deleted EGR and whatnot, what kinda of MPG are you getting now with the intake and cam swap,

[Dragthatsht]

On the air bypass, I get the koer. Thats straight forward. I'm wondering witch wire is hot. I'm guessing the other would be ground. Or does it ground through it's body and both go to a koer source.

[roxborohardbody]

im doing this swap on an automatic 1994. and the cable coming from the transmission? can someone explain how to make that work?? im knee deep in the swap and cant figure that out

[Slaminsunfire]

to 96 you use the 89-90 240sx sohc manifold
97+ the 91-98 intake will bolt up.. OBD1, 2 and other differences

ok so I need the 91-98 intake manifold since my hardbody is a 97 correct

[Nick93hb]

im doing this swap on an automatic 1994. and the cable coming from the transmission? can someone explain how to make that work?? im knee deep in the swap and cant figure that out

Im stuck at this point myself

[sicnis]

find an auto 240sx for the kickdown bracket?

[Nick93hb]

Does that mount to the throttle on the intake? Because I believe that's where it came off of the truck at.

[minijdm95]

dude i so want to do this but everybody that does this they have problems putting it together i still want my motor to run healthy everything is stock i dont want to delete no sensors/vac other stuff that is gonna make it worst just to have a 240 intake manifold

[RedAggie03]

I'm with you...Until it gets documented well enough that I can make sense of it, I'm not going to do it.

[Nick93hb]

Is it possible to take the bracket off the truck manifold that the throttle cable and all that hooks to and swap it with the one on the 240 intake?

[roxborohardbody]

I have the throttle bracket on the 240 intake. But the direction the cable pulleys go it doesn't pull the cable on the transmission. Like its backwards or sumthing.shit idk.

[minijdm95]

I'm with you...Until it gets documented well enough that I can make sense of it, I'm not going to do it.

thats what im talking about i still want my truck to run with no problems ..im still gonna do it tho im just waiting for better info

[Nick93hb]

I have the throttle bracket on the 240 intake. But the direction the cable pulleys go it doesn't pull the cable on the transmission. Like its backwards or sumthing.shit idk.

I'm hoping to get out there tonight and see what I can accomplish I'll post up any progress I make if I can make any lol.

[waker_mikie]

Any pics of where your at so far and what problems you have ran into?

[Nick93hb]

Well I got knee deep into the swap the other night and realized I didn't have the stuff to do it. You need an automatic throttle bracket that goes on to the manifold because the one I have only has a spot to hook 1 cable. And I think you need to extend the cable, not exactly sure. Then I had to delete the tube that runs from the headers to (i guess) the egr on the manifold. I made caps and plates and put that on. But I got so frustrated in the swap I decided to put the stock one back on. Now I can't get fuel through the fpr on the fuel rail. It's getting all the way up there. I have spent all night tracing and checking vacuum lines, even pulling a vacuum straight from the manifold itself and nothing. So I'm about out of options next to burning the damn thing.
I've done a good bit of searching on here for pics but I can't find any that show how to solve the 240 swap problems or what was done.

[dvdswan]

you have the fuel supply to the injectors 1st and the return side to the FPR right.

[Nick93hb]

No don't think so. The hose coming off the fuel filter I have going into the Fpr then the other one is hooked to the rail

[Nick93hb]

[1siktrd]

so wats the word on 240sx swaps on a 97 nissan auto hb? i got one with the ecu but can't remember if the ecu is for a auto or stick 240sx lol

[Nick93hb]

Thank you DVDswan I had the fuel lines backwards. Swapped around and it fired right up.

[dvdswan]

glad to help and 1siktrd, mine is a 96 with OBDII and its working fine.

[pejsa HB]

Thank you DVDswan I had the fuel lines backwards. Swapped around and it fired right up.

nick i wanna see pics of the new set up, glad it worked out for you

[1siktrd]

Hey DVdswan, r u using ur stock ecu or the 240?

[dvdswan]

stock one, the 240 wouldn't keep it OBDII

[waker_mikie]

glad to help and 1siktrd, mine is a 96 with OBDII and its working fine.


You have a 240 intake? Post some pics up if you don't mind..

hey mikie where r u located?

[waker_mikie]

On the west bank..end of gen degaulle near woodland bridge.

[mobilejoe]

will this work on a 87 z24i motor with a 5 speed??

[1siktrd]

Oh ok I'm suppose to be moving to gretna by wall

[RedAggie03]

will this work on a 87 z24i motor with a 5 speed??

No, it has to be a KA motor I believe. I'm sure it would be made to work with enough $$ and time, but you would be better off doing a motor swap.

[AVMT]

Would it be safe to assume you could use any of the aftermarket performance fuel rail and injectors available for the 240sx with this manifold swap? There is some pretty nice stuff out there for the 240, but what mods would need to be done to upgrade the rail and injectors?

[latechnissan]

240sx gasket does match up to the hb head without issues, correct?

[AVMT]

Good question. I have about a hundred various questions about this swap, but I hate to get out of line. I'm trying to research what I can on my own, but some more information is always good.

My upper and lower manifold is on the way, and I want to make sure I know whats going on before I screw something up too bad.

Keep the info coming. Thanks!

[dvdswan]

before all the hoses were hooked up. still working on a intake tube to get rid of the generic corrigated one. you know I just noticed how filthy the engine compartment is... I bet some of you guys are cringing. :rofl2:

you off road that thing with no breather on the valve cover?

[dvdswan]

you off road that thing with no breather on the valve cover?

it hasn't seen dirt yet, but I do have a hose on now. :rofl:

[pejsa HB]

lol....and for your intake dilemma. mount your battery somewhere else and run a short ram intake. quicker throttle response and gets your air filter away from your exhaust manifold

my old set up

I only ask because gaskets aren't mentioned in the required parts and tools list.

[latechnissan]

I looked up both the 240sx and hb intake manifold gasket, and they both look similar on Autozone.com. They have different part numbers though. Would that be because they are two different vehicles, not two different gasket layouts?

[AVMT]

....still trying to piece this 240 intake together........I just wanted to triple check that I can just cut my truck injector wires, and use the 240 fuel rail and injectors WITH the standard truck ECU??

The screw in fitting on the left side of the plenum towards the rear is for the brake booster hose, correct?

What is the tiny vacuum fitting right above the idle air control unit at the top rear right on the plenum? Is this for the fuel pressure regulator?

Where does the larger hardline that runs from the air regulator hook up to? It runs along side of the bottom of the plenum and under the throttle body.

Also, where do you end up connecting the PCV valve on the 240 plenum?

Sorry to ask so many questions, and yes i've searched google for hours, read the FSMs. Thank you so much for any help.
