I've been driving around my stock 94 LS for about two years and now Im thinking about getting a small greddy turbo kit in the future. I already know that the max it could produce would probably be 250whp and thats all I'd want just for fun daily driving; but anyway what I'm asking is... prior to buying the turbo kit, could I build the internals of my motor first? I read that the greddy kit was made based off stock LS engines... If I wanted to build the motor before getting the turbo, what would you recommend I do?

 

Turbo cams, upgraded valvetrain, forged pistons and rods, Cometic headgasket, ARP head studs, sleeves, etc.

Real question is how much do you have to spend?

 

I have whatever money needed if I save for it, so I could buy/install turbo cams before having the turbo actually installed? Out of the things you listed, what is actually needed rather than just good to have

 

none of that is needed. just get a greddy kit and an intercooler to go with it and you'll be fine. to get to 250 whp you'll probably want a good engine management system, but the stock motor will be fine.

 

greddy kit and a tune with hondata or crome will make a great street car.

 

Oh okay, I see... well if I wanted to produce more power, would upgrading the internals of the engines do much? Or would I need a bigger turbo at that point?

 

A bigger turbo could take longer to spool but the faster it spools the more stress on the motor, which in that case you would want to build your internals. i ran a custom kit on my LS with a Precision GT35 dual Ball Bearing which hit full boost at 2k rpm with stock internals which handled it without tuning for like 6 months. upgrading the internals would allow you to turn up more boost for more power b/c going low compression internals would allow the motor to handle the power. good luck on that and have fun

oh okay, thanks.. thats a really good answer how much psi were you running on that setup?

 

if your running on stock internals i'd say tune it at 7psi for safety....jus remember try an use a turbo that will stay in vaccum while cruising yet will give you the right power you need once you hit full throttle

would a greddy turbo kit do that? what hp would 7psi produce?

 

I believe they should post what HP gains you'll receive on the website you're buying the turbo kit from.

For daily driving though, you wouldn't need to get stonger internals unless you plan to push up the boost in your car. I'm running Rev Hard on a '00 stock ls at 8 psi.

Just get a good tune and you'll be set for a while.

 

oh ight cool, what do u redline at on that setup? or do u not rev any higher with boost and stock internals

keep the stock redline.

honestly the greddy kit will allow you to run about 15 psi max before the turbo gives up. there's some people making 300 whp here on stock internals, but I'm not sure the greddy turbo will get you there, but it may be close. about the only internal mod that would give you more power would be some turbo specific cams.

 

oh okay, so running like 10 psi with stock internals would be safe? and with turbo specific cams would be safer? turbo would definitely decrease the reliability of my motor right

 

Go here.

Also. Avoid the Greddy Kit. You will not produce 250whp on a b18b with only 7psi. I recommend drag kits + a good tune if you want to keep things simple... else just go custom and package your turbo setup to your goal.

 

stay away from the greddy kit? why? you think building a turbo to produce 250hp would be cheaper than the greddy kit?

 

I'm rocking basically a greddy kit on my LS....i think 250whp would be feasible given the right upgrades...but by then, it would have equalled the price of a non-CARB exempt kit.

at 6 psi....my b18b1 is making about 9whp/9wtq per pound of boost....with the stock 2" Greddy downpipe, 2.25 exhaust, 2.25 cat...if i get an e-cutout and up the boost...i'm very confident i can break that 250whp.

 

How long do you a turbo is good for? Like say this guy with his LS...just stock motor...good EMS... injectors all that crap...what do you think like miles wise?

so at 6 psi your making close to 200whp right? what is an e-cutout? and 6 psi is pretty low dont you think? is your LS motor stock? and what are the "right" upgrades you think that would allow the greddy kit on the LS to reach around 250whp?

I love you.

 

you should buy my LS turbo kit
