Hey everybody, as im wanting to start a project with my gen 3 3sge 1993 st202 Celica and I have hit a pickle. Im just wondering how easy (as easy gets when swapping motors) it is to put a red top gen 4 3sge motor in? Also could i just buy a gen 4 head and put it on my gen 3 block? I know the compression ratio is different (gen 3 = 10.1:1 and gen 4 = 11.0:1). Hoping you guys can help, thanks
