Hard decission? to sr or to ka.

[JsD21HB]

My friend just finished putting a sr in his girls really clean 89 coupe and let me tell ya that thing is pretty fast at 10psi burn-out clutch and problem with the boost. I was thinking about boosting my single cam but i was trying to weight out my options.
ka:
*no knock sensor
*no piston squirters
*low compression
*tough as nails
*cheap ecu tuning
SR:
*factory turbod
*reliable
*parts easily avalible
*slightly more expensive

[Monster2TG]

SR, it will save you alot of headaches in the long run. KA can be boosted, but most of the ones I have seen are just pieced together with hopes and dreams of not blowing up. I would do a KA myself, but I would rebuild the whole motor for it to take the abuse of turbo. If you wanna build up the KA, go for it. but if you plan on turboing the Ka with out rebuild, then go SR.

[Low F350]

Is this also true for the DE? I want no more than 300 hp at the crank so no huge turbo or anything... Sorry for the hijack.

[JsD21HB]

yeah with engine work. i just want a good street car not outragous or ne thing like round 210 would do maybe 230. man fuck. i dont know what i wanna do.

[O.G.Tierdrop]

i vote sr...no real reason, just like the idea of this plan i got.

ur not helping.jk.;)

[manic_mechanic]

I am prob going to rebuild my KA and build it for the turbo.

[SkinnyG]

KA.

They ~do~ handle boost well, plus once you get greedy with boost, you can ALWAYS get another KA. For cheap. And you can keep your current transmission.

[JsD21HB]

yeah im really torn.i might do the ka up and ill take it easy on it all summer and at the end of the summer ill really see if it can take the abuse and if it dont blow then im in good shape and beat its ass next year too and repeat, but that fucking sr is fast as shit.

[Monster2TG]

If you are looking for 230hp, then drop an SR and some bolt ons. That cherry red 240 I posted in your other thread made 260whp with a pretty much stock SR in it. Only bolt ons and a T28 from the S15, still stock ecu and running Apex-i AFC controller. Trust me, if you dont wanna be replacing KAs all the time and want reliable car with HP already there, go with the SR. You will be happy you did and will save you from all the headaches a boosted KA will give you.

[O.G.Tierdrop]

ur not helping.jk.;)

sr20det black top, sr20ve head, and sr16ve n1 cams, makes about 300 hp on paper, for about 3000-3500 depending on who you get it from, but its a little more than swaping heads

[GutterHXCGrowl]

Just put in a SBC and be done with it! hah

I'd say SR for the best bang for the buck.

[greasemonky89]

KA-T.org


the ka is all you need trust me it can be one hell of a torque monster.

[Monster2TG]

:puke:V8

[SkinnyG]

Yeah. A SBC will make more power and torque for less money, and even on low octane gas. All day. For years and years and years. And a rebuild costs, what, $50 and a pack of smokes? Do a V8.

[GutterHXCGrowl]

Eh, its always going to be preference of the builder/owner.

I love v8's but I'm old school like that.

I would love to put the twin turbo skyline motor into a nova though, one of my crazy ideas.

I think 50 for a rebuild is a little out of the right price range, depending on what your doing makes the price change same as anything else.

I never see much info on a twin turbo 300zx into a hardbody or likewise?

Either way, let us know what the choice ends up being, love more info!

[burrsg101]

i say a vg30 swap. the vg30e would be the easier and if boosted would make good power. bottom end handles 500+ power stock, and the stock fuel system handles about 250ish if you have the injectors that came in the pathys and hbs. parts are cheap, the engines are cheap and they can take a mad beating. or if you wanted a step up, swap a vg30de and youve already got 222 hp stock and that could be up over 250 with a few minor mods, but that swap is a little more involved. the de is also extremely tough but parts arent cheap and its kind of hard to work on(my z is a bitch to work on). but if your only looking for 200 some horse id say shoot for a boosted vg30e or just a na vg30de.

[ridin4life]

i voted ka because the money you would spend on gettin a sr($1500) you could build a ka(pistons,rods,and machine work).plus being diffrent sr is the new b18 everybody got them

[JsD21HB]

thanks guys if i can find an sr for under 2k with everything ill go that route. but if not ill just boost the single slammer. got a buddy i havent talked to in awhile he might be able to get me one for a decent price. how much am i expecting to pay for a "good" red top? ive seen them for like 1250 but i kinda dont trust that. what ya think.

[Ice]

i got a sr for $1000 just read my pawn shop add..
;)

[O.G.Tierdrop]

ive seen them for like 1250 but i kinda dont trust that. what ya think.wow that cheap, if it comes with everything i would diffently avoid that at all cost. most of the time i seen them as a package go from 2500-3000, but i would look into what ice has for sale.

[Monster2TG]

Once again, SR for trouble free problems in the long run;)

[nismopu]

INCORRECT! The hype over whelms me! How can anyone justify the expense of the SR? sure they cost 2000 from some place but what kind of reliability are you buying? NONE! For 1000bucks you can secure the bottom end on a KA to handle way over 350hp. 350whp is the SAFE reliable HP amount an SR can handle, which happens to be the KA's safe limit as well. Why does anyone think theres such a great debate over the two engines? get a clue one is NOT better than the other for boost! They're have been plenty of SR's out there that handle 500+ on stock bottom ends but now theres just as many KA's doing the same thing. hmmmm. Maybe its because theres just as many people putting the same efforts that were put into hyping the SR, into tuning and building proper KA setups. Don't be a sucker to the hype and also don't be a sucker because you rode in one "fast" car. I have freaking ridden in a 510 with an SR at 10psi running a t28 and that was a fast car. It still didn't compare to my friends turbo pickup though and its a KA-T. The SR can rev to the moon and cost you more, the KA will cost you less and be just as reliable if you TUNE IT RIGHT. Sr swap will cost you more hands down guaranteed just ask the guys on KA-t who came from SR cars. The engine is nothing but pure hype plain and simple, do the research. One last thing if you open your wallet and ask it how much do we wanna spend then you shouldn't do either. You should realistically set a goal of how much you HP goal is going to cost you, this will make you do the in depth research. peace.

Post breakdown= SR expensive, overhyped, revs like no other, lots of aftermarket expensive goodies, and a huge cult following(hype).
KA= awesome bottom end response with boost, lots of proven setups, money ahead, OEM parts at schucks, NAPA, whomever, and making one more believer.

It is e-bay, But hey, You never know!

[JsD21HB]

nismopu i was waiting for what you had to say. and ya kinda kicked me in the ass think ill just see what happens if i come across a good local sr for around 2k if not im gonna get a de and build it spending what i would have on a sr on a de. eccs.hybridka.com has info on tuning factory ecu's through a chip burner and chips i have a pretty good background in electronics so shouldnt be that bad. ill be making more money next year and should be able to build a pretty fast ka.
also dont want any thing outragous just want a srt-4 eating drifter. yeah we have all sorts of neons that have shit done to em round here.

[GITuk]

screw the both of them and put in a 350...jegs has one for 1600 new with warrenty and the jegs tranny would be 700 new...all new drive train and alot of room for more HP down the road and regular unleaded gas...that and nothing is cooler than the sound of an HB or Frontier pulling up with a V8 in it!

too fucking heavy, and total not wanting to go down that route. ls1 would be bad ass.

[thatboi_j]

If you are willing to spend 2g's on a SR, just buy ice's and have it shipped. I don't have a clue how much shipping would be or how much you would have to give Ice for his extra troubles, but you should stay below $1500 on that route

[JsD21HB]

yeah but gotta wait till tax time. ya know what i mean christmas and my girls birthday and shit also getting ready for winter. but im thinking first of the year like feb mar area.
ice if u still got it when im ready but ull probly sell it by then ill grab it off probly just drive... nope nevermind just looked it up 923 miles from my house f that. still'd probly be cheaper with gas prices they way they are now but who no's what could happen.

[lomofo11]

My preference would be a sohc KA-T. Both engines would be sweet under our hb hoods, and unique. You dont see alot of sr's under hb hoods, which makes it "cool" to have a jdm engine in the truck. Just pricey to say "oooh, jdm!". Although it would be cool. If you want dohc, grab one from a fronty. It's domestic and alot cheaper and has a little more torque. You could probably buy a dohc ka and turbo it for the price you'd pay for an sr, give or take alittle.
But to have a sohc ka that beats the hell out of srt-4's, cobalts, civics, exc. would be awesome. When you tell people that your only running a sohc engine, and they cant believe it, it would make me grin more than saying I have an sr. That's just my opinion. To each their own. good luck with your build!
