hell i'm single turbo and around 400-425.. and i got pushrods..
I could make 500HP right now if I wanted to, but I'd break my engine. 350Z's are known for 10.3 stock compression and weak rod bolts and the VQ35DE was never meant to be boosted. Once internals are done they are fine making about 500+ at 15 psi or less.
