I have been experimenting with a n/a 4g63 2.0 engine in my 92 eclipse gs manual. built a 6 bolt with
.20" over bore
b/s elim
stock new 9.0.1 comp pistions on big 1g rods
tri metal clevite bearings
stock 2.0 polished crank
2g head milled .15 (compression should be around 9.5.1)
1g cams
2g intake
1g 60mm n/t tb
It runs real strong up to 5500 then falls off quick. I found out that the 4g67 head that came on 93-95 1.8 dohc hyundi alantras is basically a 4g63 head exept it has 42 cc combustion chambers instead of 47cc. So with it milled .15 it should be close to 10.0.1 compression plus this is a 1g style port head thus giving me that top end power I was looking for not to menchion the larger plenum 1g intake & larger tb option. I think this is the best solution for n/a applications. I am in the prosses of building this head so, I will let you know how it goes.
