I have a 95 ls integra and I wanted to turbocharge it. I wanted to know what kind of turbo kit is best for an ls engine and if I had to do any internals. I don't want to run high boost. If anyone can help please let me know.

 

you can run up to 13psi on a stock motor for a while. If you get a big turbo you can run 7 psi and make decent power.

 

I've seen 10psi on a b18b like yours. They run strong and nothing needs to be done. If you do run boost though I would get a deck guard to fill in that cylinder to block clearance on the top. I probably would only run like 8psi for the sake of a lasting motor but maybe with enough maintenance you can get away with 10.

I'm rebuilding my motor actually. It's an LS also just the b18a version. Going to sleeve it , get forged rods and pistons, grind the crank and get some apr bolts. then I need a new oil pump. I am going to pust 15+ though. I'm sure your stock motor can take it if its low miles. Something around 50k or less should be alright. Anything past 100k I would rebuild. Either way, the stock motor won't take a pounding forever.

What kind of budget do you have?

 

I have a decent budget to get the kit I want and tune it right. What turbo kit would you recomend? Or does it matter?

 

From what I hear custom kits make the most power. I don't know my turbo turbines but you should consider how you use your car so you can pick a turbo that spools at the right RPMs for you.

 

My car is an everyday driver.

 

Im running 10 psi on my stock block ls daily driver. Put down 246whp, no problems so far.

 

What kind of turbo kit do you have?

 

custom kits are cool because you can get all the parts that you want, and can also get better management than comes with prefabbed kits.


its not about how much psi you run, its how much power you are making, which was hinted to here

im a big wuss, so im runing around 220 whp right now on a 200k mile stock ls motor. ill turn it up to 10 psi soon and see how that fares me

 

I'm planning on bying another ls motor with around 30 to 40k miles. I wanna run at least 240 whp. Also what price range would a custom turbo kit cost.

 

How many psi's would be safe for me to run on an ls motor. My goal is 240 whp but I want to know how much psi's I can run without blowing the motor.

 

From 8-10 should be pretty safe psi for ya. Make sure its tuned tho.

 

Virtually any turbo will net you 240+ HP at 7-8 PSI provided you have a nice free flowing exhaust and adequate fuel/tuning.

You could piece together a kit capable of that for $2,000 no problem.

 

Do you know anywhere that makes custom turbo kits? Also what type of injectors ecu ect.... would I need for the power I want.

 

im making 235whp/190wtq @ 10psi

it's fun!

 

440cc or 540cc injectors will be fine. You will need an obd1 ecu to tune your car. I would go with a p28.

 

dont worry about psi. psi does not kill the motor, power does. keep it under 300 whp and you will be safe. i run at 250whp daily on my turbo ls

2000-2500 for some nice stuff. mine was just about 2100 i believe

 

dam im getting close to 3k on my turbo kit but with top notch parts

 

if u do enough searching you'll be fine i just turboed my gen2 teg with around 151k on the clock with near perfect comp and leakdown....not sure what i'm putting down but the first shop to install did a shitty job and the first turbo i brought had bad seals...u can get back with getting used for somethings but i would get a new trubo b/c u never know what your getting...

::Sigh:: if your a wus u can keep it at that

ive had 2 ls turbos (oil pump killed one n a boost spike killed the other)

the first one made 304whp at 14psi and the other made 282whp at 11psi

both motors were bone stock....also on the first one i use to run 17psi on the street. LS-T is a GREAT setup. dont be scared to up the boost

 

So I would have no problem runing 250 whp on a stock ls motor daily driver?

no i made 304 on 14 psi n i ran 17psi daily

 

I've heard more hp per psi will hurt your motor, but some people tell me different. so, for example is it better to run 250 whp at 11 psi or at 8 psi?

it doesnt matter....it all depends on how much cfm the turbo flows...for ex if u run a GTI turbo it doesnt flow for ****...so you could run 30psi if ur only making 250whp.....but then again 30psi on a t3/t67 will gernade a stock motor lol. it depends on the turbo
