I am a owner of a 87 turbo 2 rx7 and i am considering a engine swap, now i know it would be simple bolt up if i were to buy a s5 motor turbo and tranny and my swap will be complete obviously with the harness and ecu. But what about a possible FD motor? is it just as easy to swap my engine out for the twin turbo FD? i am thinking that its alot of reconfiguration such as oil cooler lines custom and mounts custom and radiator custom but is all that worth the swap? i would really like to hear some imput on this idea cause i am not sure as to what is the smartest way to go.

Im doing this swap right now and the biggest thing other than the mounts is the wiring.. pain in the ***.. your going to need the whole ignition setup from an fd unless your running an stand alone. Custom oil lines, radiator, intercooler, bigger exhaust,and fuel pump. The s5 t2 is prolly a better swap, I just came across this engine pretty cheap. If your not goin to run over 400hp I'd go with the t2..
