CSx8213x said:okie .... let me do some explain ....
4G91 = 4G91 conrod + 4G91 piston smaller than 81mm + 4G91 head with cam degree abit different ...
4G92 without mivec = 4G91 conrod + 4G92 piston 81mm + 4G92 head ...
4G92 mivec = 4G93 conrod + 4G92 mivec piston 81mm + 4G92 mivec head ...
4G93 = 4G93 conrod + 4G93 piston 81mm + 4G93 head with abit high degree cam than 4G91
this is why 4G91 change to 4G93 head got the power different ...
If i'm not mistaken .. the height of the head also got abit different between 4G91 and 4G93....
pls correct me if i'm wrong ...
