You can't use cams right? Keep your headers, run a Hotshot CAI and up your fuel pressure by 5 psi. I would put a clamp on K&N or JWT POPcharger on it because the Hotshot filter is not so good for filtering. Get a JWT ECU. Run a 2.5" exhaust with stargith through peforated core mufflers.racersd2 said:Questions for the sr20 motor gurus. Im building a 91 Se-r STS contender. and im looking for suggestions for the best intake/exhaust combo for SCCA STS class. This is not my first go around with se-r and autocrossing.
While Horsepower is king I think that throttle response and efficiency would be better in this application.
I do have a HS genII header and UR pulleies
ported intake and throttle body with a bored maf maybe?
Will a GTir quad throttle body work with N/A motor?
Now as for suspension I'm all ok there.
All suggestions are apperciated and welcomed just remember it must be STS legal.
Bored throttle bodys, MAF's etc, are not effective until you get over 180 whp.
