Default Greddy twin turbo

I haven't been able to find anything about power gains for the 350Z's Greddy TT, but any guesses on how much of a gain of HP and TQ I would get adding a Greddy TT and forged pistons?????

I've seen that site, but it doesn't say anything about how much more HP I would get after forged pistons.

Forged Internals will lower the compression ratio, and allow you to run more boost. However, there is only so much power you can make before you need to start replacing things like the tranny. There is only one way to find out I guess. I would guess you could run maybe 20 psi max with forged internals. The 18G turbos are most efficient in the 16-20 psi range. Time is the only way we will find out.

This is true. It's also kind of a good thing, because the stock VQ35 will probably only handle around 10-12 psi max, so having the 18g/TD05 turboes leaves room for more power if you decide to upgrade your internals/lower compression and you won't have to buy new turboes. You'll just have to turn the boost up.
