Does that turbo kit you guys are talking about have a thicker head gasket by any chance? to lower the compression? I know that when I had my 350z I saw a bunch of them blowing up with the stock greddy turbo kit which was 5.5 psi so thats y im really concerned about the VQ37 lol

I've personally seen a 350Z that had gone through about 3 engines running the Greddy TT... Sounded like it was about to go through its 4th when I heard it running... He'd never gotten it tuned tho so that's where he messed up big time... I've had a 350Z running the same Greddy TT Kit pull on me like if I were sitiing still... So yeah, when you TT, BE SURE TO DO IT RIGHT!
