For the Op, I'm totally happy with what I've done so far, but then again, I never had any illusions or need to hit 300hp.

Good luck.

actually, yes I have, but I wasn't into naming every intake system. it was just to make a point about cell's.

Maybe I'm missing something here with the talk of bigger turbo's....
You can build enough boost with the STOCK unit to blow a piston with a poor tune...

right but flow drops off. essentially a turbo that flows more air at 16psi will perform better and SAFER than a turbo that boost 19 psi but doesnt flow as much.

just keep the tune around 18psi (which can be requested) and all should be reasonably safe. each time ive seen piston failure its been about 20-21psi with is too high considering the compression ratio.. unless you double gasket the head or add dished forged pistons or something
