After looking at all the costs for building a 3t/2t hybrid, including an almost entire rebuild, what, if any are the difficulties in putting a 4agze into a ta22? bolt in and then wire up? or mount mods required? Also, would the power output be sufficient for a fun ride? The 3t just isn't quite cutting it...punchy, but just lacking the twin cam feel. mates want me to put a 2jz or a RB26.....but unless they want to pay for it they can get jammed....cheers.
