very nice. we did the stage 2 GTM kit and we were pushing up around 530whp at like 7.5-8psi on a stock block. twin GT28s. we have an interesting build story though. short version is we filled up with bad gas and it destroyed the motor. we took the insurance money from it and put it towards a stroker and full build lol. i posted some of the main stuff in my intro thread somewhere. by the time he cheated on me it was up over the 700whp mark on an aggressive tune with 92 octane.
Hey if you have any questions about items for your 370z when you get it let me know. I have built two now. One for my wife, and still working on mine. Im no expert but have a good grasp on what is available out there.
