Hey Hey this summer I plan on swapping out my 12a for a 13b rew 1992-1995 motor into my 1985 rx7 anyone know wheres there any good reading material out there that will help me The rear end and the tranny are being swapped to I will be using the ecu and wiring out of the 1992 -1995

 

You will need the trans from the 1992-95 due to the thicker back plate. I would go with the TII motor/trans. It is cheaper overall.

 

Go to the 1st-gen section - there are a couple stickied articles on T2 engine swaps.

Why bother with the REW engine? It sucks... if you care about power you'll be throwing the stock turbos away for a signle anyway.

Also beware that "1992" technically means FC in the US, not FD.

 

Go with the TII it won't break you like the REW will and you don't have to deal with the million vacume lines and tubes and carp. the TII easier and less fiddling with stuff you don't need.
