This might be a silly place to ask i dont know, but what motor would best suit a r32 gtst with standard diff ratio (4.3)
I have a standard bore rb30 bottom end waiting to be built into a 3.1 but always wonder if i would be better off with a 2.6,7 or 8.
Both motors would be fully built with 9.0:1 comp ratios
Thanks guys
r33 racer what diff ratio are u running and how do u find it etc.
