i bought a 1990 naturally aspired rx-7 and i'm wondering aside from teh 13bt block, what else would i need to complete the swap. thanks.

 

ECU, wiring harness, tranny, driveshaft, rear end... search around their are write ups.

 

go to the FAQ for 2nd gens > click engine > browse the two links listed under "engine swap"
