If your gonna rebuild a 4g63 might as well go turbo.

But, if you want to build a N/A motor. Go High Comp- 10.5:1 - 11:1. Port and polish head. Bore .040 over. 1mm oversized valves. Cold air intake. 100lb shot of Nitrous.
 
Can you run compression that high on a Non Turbo 4G63 2.0 liter? Also where would you suggest to get the oversized valves for the DOHC 16 Valve? I am also doing a rebuild on a 2.0 Liter NOn Turbo 92 eclipse. I know mine is a 6 bolt but later years are a 7 bolt.
