1999 Saturn SC2 Problem
I have already replaced the secondary air injection system, ERG or EGR
valve (don't remember), the manifold converter, and have checked the fuses
and fuel pressure. Thoughts? BTW it is an automatic tranny, so no clutch.
And at points you may hear a high pitched "whailing" kind of noise. That is
actually my car around 4000 to 6000 RPM's...
Who races a saturn 4 door car?
My 1997 saturn SL1 converted. I took out the sohc and put in a dohc,
header, 2 & 1/2" Exhaust with Dynomax muffler. High voltage
MSD coils, 8.8 wires. It had a bored throttle body and true cold air
intake. I installed an egr block off plate and I used fuel injectors from a
Pontiac grand am gt. The transmission is the original 5 speed from the sohc
setup which has lower gearing. The car was dropped a little by cutting the
strut springs. The wheels are 16" aluminum. The guages were changed as well
with the motor swap as can be seen at 4:57 in the vid, so the readings are
accurate. Note how it pulls from 60 to 90mph. Pretty decent for a naturally
aspirated 4 cylinder.
