Thread: Who are some companys that make quality turbo kits?

Like it says im looking for a few diffrent turbo kits. Ive got a 97GTp with 2.8 pulley larger injectors aftermarket computer TB conversion with 1in spacer. . The only prob is i spun two rods. So since its gotta come out i plan on upping the HP while it is. Thanks.

Im getting a feeling that somthing aint rite here.. These parts was on it when i bought it. I never gave it a second thought since it had bigger injectors,pump,and zz computer. The air fuel or egt gauge didnt show signs or lean. Ok guys take me shool on whats needed to not smoke this thing again when it goes back together. It ran good It went 8.52 in the 1/8. Thanks To all.

Put the supercharger pulley back to stock which is 3.8. Your running way to small of a pulley. I also read that zzp pcm's (your computer) are no good.

Start there^^^
then put your pulley back to stock.

and please, make sure you read that thread. everything you need to know about making more horsepower is in it. you might as well sell the 2.8in pulley unless you plan on putting a lot of money into your car. you're at least a cam and intercooler away, and even that's probably only good for a 3.25

zzperformance.com sells the best turbo kits. IMHO the Z3 is the best option cuz it's good for 500 hp and the only tranny chain available for our cars currently can only hold up to 450 whp. The discontinued GMPP chain held up to 800 hp back in the days. Avoid purchasing a new CT kit from 3800performance... I'll be lucky to get all the parts and have good customer service.
