Yes,lots of fabbing
If you are good at fabrication and know some wiring very doable,if you have to hire someone to do the work,it will cost more than you'll expect.
Engine/Transmission adapter(then indicating runout and locating dowels so you don't blow clutch up)
Engine mounts
Peripheral mounts-Fuel filter,Coolant ball(if you keep the enclosed system)intercooler etc.
Then comes the wiring.
