FI 99 ls1 help
okay so I am buying a compete stock ls1 with 16k miles on it and planning on boost. my question is what has to be done to bottom end to hold 4-6 psi of boost, looking to stay in 400-550 hp range.. I know the heads that are on it are 853

Nothing, i put 20k miles on my stock engine with 12ish boost. 4-6 lbs is peanuts. If; no when you start upping the boost i would recommend adding a meth kit to cool down intake air on a stock engine. My stock heads were 799 i was around 550 ish with 1 7/8 kooks headers and full GHL exhaust. Don't worry about 4-6lbs you can run that all day.
