1ggze is a 2.0 litre 6 cyl supercharged engine, good and strong but heavy.
personally a SR20 DET would be the go, with the right mod's it'd get close to what you want with out having to cut too much of the car up. all alloy engine as well,less weight=more speed.
could try a soarer(lexus) engine,quad cam 4.3 litre,alloy V8.
anyhow good luck with it,and if u need any info on the car this is the place you'll find it.
