I have a 1989 GTU, 13b NA ofcourse(manual).
I want to swap a 90+ TII into my rx7.
I was wondering if there are any complications I should know about before I start this swap.

I will be buying TII motor/tranny/clutch/driveshaft/exaust/new motor mounts
The engine will come with everything, including ECU, wireing harness, intercooler.

I there anything I might be missing? Or common problems during these swaps?
I would appreciate your help alot.
Thanks
