i have a ls with stage one crower camshaft, toda camgears, crower springs and retainers, blox intake manifold, fuel pressure regulator, fmu, 440cc injectors, safc controller, chiped ecu and a greddy turbo. people told me that i can boost up to 12 and be safe without blowing my motor. but is it tru?

 

Why do you have an AFC, FMU, and a chipped ECU? You only need one of them, so ditch the AFC and FMU and stick with the chipped ECU/larger injectors for fuel management.

It's sounds like you need to do a little research too. You could boost as much as you want (10-15psi or so) with a good tune up to around 300whp, although the rod bolts suck on the LS, so if your motor has a lot of miles on it and you plan on boosting a lot you might want to change those. Don't pay so much attention to "psi" because it will vary with different turbos, pay more attention to whp.

 

here is the ls turbo thread. its currently 14 pages of peoples setups, who is doing what, who is making what power, what works and what doesnt and so on. its definately a good read and will help clear up some of your questions.

Just to make is quick and short your fine. I have stock everything running 9 lbs and i have been good for a year drive hard. But now im looking for more so the whole set up it getting throw out in with the new. This is on a b16a2 though little different not much

 

its not how many psi the motor can handle its how much hp . Some turbos make more hp per pound than others . ls's can handle around 300 hp stock
