What are referred to as quote "redtop" and "blacktop" motors are all essentially the same s13 motor with some minor revisions; blacktop being newer.

As far as NVCS, only the s14/15 motors came with that despite being in production at the same time as 'blacktop' s13 motors.

All that being said- I highly preferred what the Jim Wolf Technology s3 cams offered on what was essentially a stock blacktop SR over tomei, personally. and I'm a HUGE tomei guy.

I too am debating a new set of cams on a recent redtop sr20 install. This time I might go with JWT s4 despite having a gt2871r again. I might eventually want to go to a t3 turbo, so having a slightly more aggressive cam now is better than another purchase or an under-performing cam down the road.

for future reference, this is a good place for small questions:
