need some opinions on what to do (SR or KA)

[unanswerred]

well this is a noob question that is asked like 7 times a day here. and i have searched several forums including this one. talked with several people and im getting mixed opinions. ive got a 91 fastback. 143xxx miles. just bought it 2 weeks ago. prety legit condition as far as i know right now. completely stock. im having the hardest time deciding if i should turbo the ka or swap an sr. since im new to this im going to have a lot of help from some friends but i still would like to cut out as much error as possible. help me out.

heres the whip

the old 240 and the new one the day i got it(wing and rims are long gone thank god)

[pancho y onions]

First do a compression check. If it passes motor is basicly read to be turboed. Im almost done on my SOHC turbo and i pieced it togethr for only $1500. If you get the right tune and dont half a$$ on the fuel, you should be good to go.

[WDRacing]

First things first, it's a car...not a whip. Whip is something that was made up and sounds retarded. Very similar to kids wearing pants around there a$$...

The SR vs KA debate is definitly one of the more frequent discussions. If your current KA is in good shape then it's worth keeping IMO. If it's going to need a rebuild then it's worth looking into a swap.

You have to ask yourself a few questions. What are your power goals? Whats your budget? Can you do the swap yourself? Answer those and get back to us.

well i dont relaly have a budget. i do. but i realize if i do an sr im going to have to save up more. and if i do a low boost ka i could get it done cheap and over time build it up. and a friend of mine has done sr swaps and said he could help. and as far as power goals. im not really sure. if it were an sr. pry 300. if i went ka. pry low 200's at first.

8psi set-up you'll be happy with and can do for under 1500. Depending on turbo should be around 220-240

[unanswerred]

see i figure for another 1000 i could get an sr swap. and that could be a budget build. over time build it up and worry less about something going wrong.

[240sxvaj]

IMO go with the KA build and keep it KA

i just blew my ka on stock internals but then i was putting 247WHP w/ 241 WTQ on a redtop t25

now im doing a FULLY BUILT KA

i say KA are alot faster and more fun when turbocharged

get in a KA-T and compare it with a SR

you will feel the difference

[unanswerred]

im sure a fully built ka would put a t25 sr to shame. its a bigger engine and of course a t25 is very restrictive.

what was your engines part list for the ka and how much did you spend on the whole kat build??

i spent alot just for my parts because it was all brand new parts

after the tune about a week later i install my Z32 MAF and it didnt really made a difference. i felt it picking up a little faster only.

sr are good, but if you planning to make as much power as me you going to spend a lot more than what i spent and probably boost higher.

you're paying around 3k for the full swap(cheaper if you doing it yourself). probably get around 170whp on a dyno for stock s13 sr, and to make over what i'm making at stock boost you probably going to pay close to 2k.and low 2k for my motor build and i'm bullet proof!

to sum it all up 2.4L>2.0L

thats a really nice setup you have. it looks identical to what mine would be if i went kat. how do you like that spec II? thats the exhaust i wanna get. so your on stock internals? how much you boosting and putting down

[unanswerred]

heres what it looked like when i bought it

[240sxvaj]

I always loved the spec2 style, it also sounds nice not that loud. when i made 247whp i was on stock internals, but after installing my ecu i didnt know what happened and blew piston ring #2. I just got all my engine parts in and ready to take my motor to the shop to be fully built!

i'm planning on making 300+whp daily driver with a GT2871R hoepfully i can achieve this power with 9lbs of boost.

[WDRacing]

Thats gonna be rough with that turbo...the average is only 10whp per psi of boost.

SR or KA?.....Me personaly im getting an SR swap when i get my s14but i think it depends on what you'll be doing, KA's have a bigger displacement,more torque so lower RPMS right?....SR's have higher RPMS wich is better for drifitng...not as much torque...so if you wanna go into drifitng....lean towards that SR swap...if not...hey man keep the KA...you could probably put more HP in the KA's too.

i dont really have a specific hp goal. and there is no drifting tracks of any sort near here. but my goal is to have a low 13 second car. possible right? maybe break the 12's. who knows.

did you get the 2.5"?

id say thats a pretty good goal on 9 pounds.

the list im sort of thinking about right now is:log mannit3/t4dsm bov or some bov hotpipe comboebay intercooler and piping kitwalbro 255370's(maybe bigger im not sure yet)spec II exhaust safc IIstock clutch until it slips itself to death

10 psi daily until i can build the engine.

[Tayluh_240]

well...I would keep the KA and load her up with performance if you wanna get 13's and possibly brake the 12's

[unanswerred]

thats what i was thinkin.

whats a good cheap manifold for a noob

[480sx]

Man dont down on the SR too bad guys, its a great motor. Its low end blows hard, when your driving around town in low rpms it feels like your in a grocery getter. Top end feels great though, the damn motor pulls like a beast @ 3500-4000 on up.

I put down a 8.5 1/8th with street tires, VLSD, FMIC, Megan manifold, 3 inch strait exhaust, and a maxed out T25 on a redtop. That works out to be like a 13.2 in the quarter, which is pretty freaken good for a stock motor. Not sure what that works out to HP wise, i dont know what my gutted s13 weighs.

OP - Go with a JGS log manifold, you will NEVER regret it. Good to 500 hp, and will last you a life time. Or you could take your chances with a SSAC..

i think they only make one size for the spec2 on the s13. which is like 3" i know for sure it's not 2.5".

Dont blow your motor and get bigger injectors, deatschwerk sells for cheap and quality. they also do core exhange so for a set of 370cc you get 100back. also go with e-mance ecu for quality ecu tune, for around $150 you can get jasons email off e-mance.com let him know Blong sent u. Plus sent him the whole ecu so that he can install it and make sure it works!

You will be safe with this set-up and make great power, plus you can get the car dynoed and show him the dyno chart w/afr and he can fine tune.

always have wideband you will love your car

[unanswerred]

yea that sounds like a legit idea. so its 150 there and back tuned for the emance? whats the turnaround time on those?

[Craving4Boost]

keep in mind that one must never go into boost with the menality that KA-T is the cheaper route over SR. both motors will be expensive as forced induction is just plain expensive. Sure SR is $2000 but you have to account for what it includes. turbo, mani, ecu that will make everything run like stock, harness, transmission, etc. Both motors are pretty equal IMO, it's only a matter of taste.

The only reason why I went KA-T is that there is just something about NA-T cars that feel brutely harsh and I love it.....been in the game for a while and still dont really understand why...compression ratio maybe?

good luck though...boost is boost...it'll be fun regardless.

[uselesswingsr4penguins]

id just turbo the ka if the motor passes a comp test and you dont have any oil or overheating issues but thats just me

[240sxvaj]

I'm not too sure how longs it's going to take but i heard its pretty fast, i actually took my ecu to him in san diego, CA and he chipped in less than 5 min, but its because he already got the chip tuned ahead of time. E-mance is good and also enthalpy is good but enthalpy cost around $500, so it depends on what you want, i think enthalpy have been in business longer, but there are many success in e-mance, so i wouldnt worry about it.

[unanswerred]

hmm i will definetly consider that. i think the first thing on the list is exhaust. then save start compiling all the parts i need so i can do the install in a weekend.
