Your limitation is not boost per say or a certain amount. Remember 8 psi with a 60-1 is not the same as 8 psi with a T88. Your limit is cylinder pressure. Also your incoming air temp plays a large role. IAT's of 140+ vs IAT of 100 deg makes a big difference, since your density has changed. Their are to many variables to say X amount of boost is what the stock shortblock can take.

Why hasn't anyone made a 50 state turbo kit for the ls1? Seems like that would make an easy 500+ hp. Is there something about the California smog laws that prevent this? Also, wouldn't a turbo car be quieter?

well without the variables to consider, just plain out boost numbers, would you not go over a certain number on stock bottom end. i dont plan on throwing a charger on my stock bottom end. i am gonna have it built first, but i was just curious! and is there a certain charger that works better than the others out there. i am not to fond of the turbo's, i always like to pop the hood on a car and just see that super charger sittin there whining away! i am really like the magnacharger from what i have done my own research on, but what do you think of it?!?

4.5-6 psi on a turbo only.

6-9 psi if you are using an intercooler with the turbo.

I just recently got my car and was looking at turbo kits. which sts turbo did you get. and what do you think would be the best for a stock ta.

I got the upgraded kit with the GT35 and dual stage boost controller.

On a stock T/A if you don't plan on going crazy with the power then I would get their base kit and used the money you saved on a turbo upgrade and buy an intercooler or a methanol kit. You can make great power on the base kit (410-440 bone stock) and with methanol or an intercooler defiantely more due to MUCH cooler intake air temps. I would recomend bigger injectors and custom tuning though. The really cool thing about this kit is that you can start off small and add peices as you go to acomadate a budget. If you decide to go crazy later you can swap turbos, add intercooling, fuel system, forged motor etc.

We are doing my intercooler this Thursday and I will report on how much of a difference the going from 150deg IATs to 90 or below will make on 5-6psi

I am also leaning very heavily on getting the STS kit but I would like a little input from some people that know more about FI.

I currenly have a stock head, stock bottom end 02 TA, B1 Cam (221/558), Jet Hot LT's, Hooker ORY, built 4l60e, Vig 3200.

What I have in mind is getting the base kit with the turbo upgrade for the T67. My concern is will this produce too much boost for my bottom end? I also plan on getting one of the OBX FMIC's. I don't want to have to go through the bottom end for a year or so but I would eventually like to go lower compression & forged internals & go higher with the boost. Will the T67 be too much and or will the T60 be adequte for when I want to bump the boost up some? I know I will also need to upgrade the fuel system at some point as well. I already have tuning on my car for it's current setup & I have lifetime tuning at MTI for retunes so the tuning isn't an issue. Will I need to upgrade my fuel system since I already have some mods & will be putting the turbo on as well?

Thanks for sharing your knowledge!

Marc,
You can still just run 5psi with the t-67. It will come on a little later and hit a little harder though. The biggest difference with the t-67 is that it has the capability of making more power. The 60-1 will not be as efficient past about 500 hp where the t-67 will.

when i start seeing some big numbers from an STS kit ill consider it. For now im sticking with going with a 408 with alot of juice cause i need at least 700rwhp. Pesky KB cobras lol
