I like s14 sr because it has VVT
and other than what it comes with stock thats about it.
VTC helps create tq at lower rpms... but once you go above a 256 cam or play with the retainers or springs you have to disable it.
s15 sr's are getting cheaper lately
wow s14 sr's i have seen run no more than 500 compared to a s13 blacktop
