IIRC it would bolt up fine, however the 13b tranny is a little beafier then 12a tranny.

hey, so i bought an 85 RX-7 with no engine for cheap,

and wanting to turn this car into a drifter what are the possible engine selections i have to choose from that are straight drop in, or close to it with a few little mods?

the 12a or 13b i believe both drop straight in, but if you go for a 13b you'll have to run your own harnesses and make sure you have the correct ecu to match the engine.

what about the other makes and models of engines, like 1jz-gte or like Rb20's or like ford 302's what other engines can i drop into an rx7

a mechanic friend told me something once, "you can do anything for enough money." in other words, you can put anything you want in it, but it's going to cost you more the more unique it is
