TMRacing

I currently reside in north america and am looking into doing an ej20 swap into my rs. I'm wondering how the versions differ form each other in terms of tunability, and reliablility etc. I've heard that the ver. 3 is best for high horsepower because of it's lower compression - is this true? Any information that can be given would be greatly appreciated (It's next to impossible trying to find information regarding the ej20's in canada.) Thanks.

I'm also from N.America and I'm going to do the same thing in about six months. E-mail me and we can compare notes.
