i have yet to find good revies about this setup...4.63 final drive with NA KA? there are a bunch of reviews for turbo'd cars but not really much for NA KA. this setup would be for a track car, so MPG is out the window. how big of a difference is there going from 4.08? how much faster does it feel?

 

I have had 4.63's for about 6 years with a Nismo 1.5 lsd.. Highway driving at 3500rpm lets me drive in the slow lane. 4000 if you want to stay with the flow of traffic. I have JWT cams and ecu. The cams sweet spot comes a lot quicker .
