ummm...out of those, a 4g64 in my opinion, its a 2.4 litre sohc but a 4g63 head can be put on it and then you have all the 4g63 parts at your disposal to turbo it. if your going to attempt that, talk to a few people around here that have done it and get a feel for if you really wanna go through with it.

what car are you using for this btw? im still trying to understand what your wanting to do to what model.
