i dont see how does a tranny from 1.8l is goin to fit 4g63 engine. from what i see F5M22 tranny is used in the 1.8l and 4g63 N/T , and FM533 for the turbo models. but than , if the FM522 mounts to a 4g63 N/T than, y wouldn't it fit a turbo model. i dont know, probably i'm wrong but u need to do some research. also i'm sure that the gear ratios are different, so find out how would this affect the whole thing. the 1.8l tranny might not be strong enough. just my 0.02$
p.s. here some specs...
