Make sure you run an agp s3 waste gate if you can still even get them. Here was my complete set up.
Ported S3 by bob from form and function. 42lb wheel
AGP S3 waste gate actuator connected to factory solenoilds
S3 pcm with toys. Used dab to control boost. Spiked 25 held 22 on and off hom.
Form and function ported intake manifold.
exhaust depot super beast fmic
maxxfab s3 o2 housing. S3 manifold was ported to match the 3.75 inlet of o2 housing.
needswings downpipe.
Kinetic Motorsports tb
Rage tek 10an fuel rail.
Aeromotive fuel pressure regulator with my own return set up.
Stock S3 injectors and fuel pump modified for return set up.
I had the mopar clutch. Was slipping a few months before I sold the car.
It had S3 coilovers
agp motormounts
ran it at the track on 114 octane in hom with micky thompson et street drag radials.
no big turbo or nitrous srt-4 could touch me from a dig or roll in hom. even off hom i was a big contender.
Never dynoed it. It was enough to run 10.70's @ 125mph on an amazingly prepped track.
My set up was pretty simple. No one could get how I did it with out an aem or any other fuel management. Its simple. Keep the pcm in the loop with boost and fuel. The S3 computer does wonders in hom. If you don't have toys its not worth it and might as well get an aem or hp tuners. Car drove like stock. Not one driveability problem. But for my real opinion. Sell your srt-4, get a daily driver and build your own car thats not fwd. I spun 3rd gear on the street and by the time I caught traction and was reeling in the other car and passing we were already at 140 +. Drag radials were a must all the time.
That was before my return set up and ported intake and tb on drag radials. I put a bleed in the vac line that went to the S3 fuel rail to get a better a/f ratio. That was an 02 z06 with a 100 shot. I accidentally left on the second honk, let off, then got back on to keep it as fair as possible.
