Re: difference between 4G63 in the Eclipse and EVO
The only performance related internal differences I am aware of is the compression, pretty sure about cams, and I am sure the heads all flow different. Stock 6 bolts all have 7.8:1 compression ratio where the 2g has 8.5:1 and the Evo is 8.8:1. 1g cams are a step above 2g's and Evo cams are a step above the 1g's I'm pretty sure.
