So I have a short list made out for things to upgrade on my R32 GTR. This list as of now is as follows:
Power FC
Deatschwerks low impedance 1000cc injectors
Walbro fuel pump
Nismo twin plate clutch
2860- 7 OR 5?!
Car already has an exhaust and intake system (HKS).
My question is to go with the -5 or -7?! I have read soooo many forums and ppl saying different things so I’m feeling it comes down to preference. I would like to make 450-500 hp at the wheels. I understand that the 7 more or less spools like my ceramics do now but will have more top end, where as the 5 comes in higher in the rpm range but have a ton of top end and can make serious power. I just want to make sure that what I do be safe and reliable at the same time if I go with either route. Any recommendations are appreciated.
Thanks!
