How much boost pressure can a built VQ37VHR withstand?

Boost your stock engine first. Get it tuned well and stop at 550-600rwhp. Done right, it will last. If doesn't last, its very likely that whoever did it wasn't going to have better results from a built engine either. Except you would have spent twice as much and not had your car for 3 times as long just to end up with an empty roller and boxes of parts. Yes there are exceptions to every word I say, but we all know not to plan on being an exception.

Use the boosted stock engine as your "feeler" before you dive into the deep end. Your experience through this will help you make better decisions on your full build if *IF* you still think you need more power.

The 370z is no GT-R... past 600rwhp starts to get a little pointless unless you are going to make commitments towards traction that take away from why you purchased a Z-car rather than a Mustang to begin with.
