I'm currently in the (very long!!) process of putting a 1G-GE into a KE35. I know that within a few months the power of the 1G won't be enough so I'm starting to do some research now. I've been looking all over the place but haven't really been able to find much info on what the differences are between the 1G-GTEs and the 1G-GZE (apart form the obvious!!)
What I need to know is what are the internal differences between the two??? what are their respective compression ratios?? are the pistons the same?? etc etc
