    No actual experience with this swap I'm afraid but they're very simmilar engines with only 200cc difference. I'd suspect that just swapping over the long motor and sticking with the 5M-GE management will give a satisfactory result.

    For the same price, get a set of extractors, head work (port and polish), and a metal HG
    bobs your uncle!
    If your sick of the power, its just the auto box, its like a falcon auto a POS!
    Manualize it!
    I used to own a mx73 cressida with the auto, it was SHITE!!
    Manual was a totally differnt story though.. They are a good motor spend some money and you'll see.
    Thats my two cents anyways
