hehe... My favorite saying, S series for street, R series for race.....
I'd love an S15, but a 1994 R32 GTS-M is the one for me..
The SR20DET is a nice motor, but for reliability, and overall performance, the RB25DET is generally stronger all round... and when you're working with an R series, You've got an RB platform right out of the box, and then its just $5k to move to a RB26DETT
An RB26DETT putting all its power to the rear wheels is very impressive
Thanks H,
