Power Goal.

It's guaranteed that in the future (sooner rather than later hopefully) I will purchase a twin turbo kit for my Z. I've been looking all over the place and finding all sorts of different cars with TT kits making different power.

Most of them are making somewhere in the 450Whp range, a few are making more. I know for example there is a white nismo Z for sale on the site making 490whp at 7 PSI with the stage 2 GTM kit. It also make 560whp at 11psi.

From what i gather this is all on stock internals, even stock clutch!
My goal would be more similar to the white Z, I would be perfectly happy with those numbers. But if I were to go that route eventually, what kind of supporting mods am I looking at? Would the 600cc injectors that come with the kit support that much power? If i'm not mistaken, it comes with a wallbro 255 fuel pump, I am wondering the same about that.

An aftermarket exhaust is obviously a must, I had one custom made here with 3" piping, and I am running test pipes already. Boost controller was thinking about the greddy profec, but not 100% yet. Have a clutch on order from zspeed already, (southbend stage 4, with flywheel and heavy duty CSC)

Anyway, any and all input is appreciated, I would love to put down similar numbers in my Z!
