how much boost can you run on a stock motor before you need to upgrade the exhaust, injector, add on a blow off valve...etc....

 

u should run no boost if your not gonna upgrade all those items. Exhaust doesnt matter so much as long as u run open downpipe. You for sure need to upgrade injectors and you for sure need a blow off valve. You should do some research before u put a turbo on your car. Theres a lot more to it then just putting it on and going.

 

General rule of thumb, you can run 14.7 psi before needing to install a turbo.

 

i can see it now...

compressor surge here we come.
