Ls1 STS Turbo?
I have a stock automatic 2002 Trans Am WS6. I was thinking of getting a STS Turbo system installed, but would like to know if this system is reliable on a stock motor. I see there are no intercoolers with this system and wonder about issues with access heat. I don't plan on putting alot of miles on the car and I also don't plan to race and abuse the car after the install. Anybody with this setup or knows anything about this system please give me some feedback. I know this has probably been talked about in the past, but I didn't see anything specifically answering my question. Thanks, Ken!

I have a STS turbo on my stock LS1. Your car will do just fine with this setup. I run 4 psi daily and 8 at the track or when I'm racing. I've had this setup for over a year and my motor is completely stock and running strong. I would suggest you upgrade your fuel injectors and fuel pump with this kit for better performance. Intake does not need to be done and what do you suggest he does with the exhaust? It is an exhaust driven turbo so the exhaust gets done with the kit. I will be happy to answer any questions you have. Feel free to PM me.

You wont NEED to upgrade the fuel with only 4lbs but just to be safe I would upgrade it. Besides...you say you wont, but we all know you'll want to turn the boost up lol. Might as well be ready for it.
The norm for stock engines is *roughly* 8lbs. They seem to hold up quite well at that level. If you want to play it really safe, upgrade the valve train and put some 6.0l (lq9) heads on. It will lower the compression and make the setup safer. There are a few people running 12+psi on the stock engine and well over 600 to the wheels and their cars are holding up fine. But you better make damn sure the tune is dead on.

No you wouldn't HAVE to upgrade your fuel system, I just suggested that you should. And once you get the turbo on, trust me, you won't just want to run 4 or 5 psi. It's addicting and you'll want to be running more.
