Ok, il answer ur Q coz probally noone else will - Nexty time check the st162 thread in general discussions or do a search
The gt4 engine(3sgte) can be fitted but it will need a bit of modding. engine moutns wil need to be changed slightly i believe, its best to probs upgrade them to HD items anyway. Also with the gbox ul have to block off the rear transfer to effectuvely make it FWD only. u'l also have to mod the CVs and change somethin elsde - i cant rememebr what it is. other than that ecu will have to be changed and yeah...
