nobody ever claimed that you couldnt make an sr20 run fast. what people are rightfully claiming is that it is an inferrior engine and that is is not practical to replace the vg30dett with such an engine, expecially $$$-wise. the vg30 with easy to do bolt-ons will outperform sr20's that have gone as far as new cams, pistons, the works... and as far as reliability. how can you top a stage 3 turbocharged car like the TT car that will still run 150k miles without anything but timing belts?
