Well other than the fact I just love the RB26, I live in an area with alot of snow so AWD would make it into a daily driver. Don't think I'd want RB30 head though, although thinking about it. Also, my goal is around 500hp and Ive heard the RB25 is less reliable past 400hp while the RB26 is still good to 500 before forged internals.
Would it be the same difficulty putting in a RB26 into a GT or a GT-T?
