Can you just replace the stock hb Throttle Body with a larger one & get almost the same gains? If so, what Throttle Body would fit in the stock hb location?

Default 240sx intake swap

hello quick question we just did this swap on my friends 95 pickup and the tack quit working after we swapped out the ecu's and it works again when we put the old back in is the ecu bad or maybe the car we got the ecu out of didn't have a tack?

This is the problem with switching the ecu's that I haven't figured out. Haven't seen where anyone else has either. Not really a concern for me. Everything else works fine.

As far as I know. Spent a couple of days on it and came up with nothing. The tach and ecu just don't work together. I get some random movement but nothing reliable. Was gonna see if there was a difference in the resistors. Just haven't got around to it. Aftermarket is your best bet.

It's been long ass time since I wrote this write up and posted anything on here buy from what I remember the truck uses a ecu output for the tach signal and the 240sx and use stanza use the ignitor for its signal.

JsD21HB would you do everyone an amazing favor and rehost your pictures. Photobucket dropped its support of linking and it killed great threads like this. I've been using imgur, I don't know how it ranks in the world of image hosting, but it allows me to link pictures.

Thank you in advance!!

Edit: just so you know, all your pictures are still on Photobucket. They didn't delete any of them.

I know this has nothing to do with the intake swap, but has anyone ever tried to put a 400 sbc motor in their hardbody?? I just scored one for a hell of a price. Let me know! Message me too if you'd like, I have tons of questions.

I hope JsD21HB doesn't mind me hosting the images on another site and embedding them in a quote. I was still having a lot of issues seeing the pictures. If you have a problem with me doing this, let me know and I'll take them down.

I am finaly done with the 240sx intake install.
After getting lots of wrong info here is the stuff that is true.



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.



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.



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.
