#3980, "RE: Need some help building a reliable 4g63 in the 12's." In response to In response to 0 Dec-26-03 06:45 PM by weepul
Mine's getting to that point....here are a few things to consider:
Big 16g turbo lightened flywheel remove balance shafts 1g throttle body and ported elbow gasket match exhaust manifold port o2 housing injectors pump s-afc
those are some of the more "damaging" mods I have done to mine. It's not tuned just yet (afc not installed), but I'm told it should be able to do 12's easily
