Second, get a 13BT, not a 13B-REW. It's not going to make a difference for you except to you wallet. Get a complete TII - any year will work (87-91). I would suggest getting the 87 as the car will cost you less. S5's get expensive and have more electronics. The TII tranny and rear end are bulletproof.
You will need almost everything from the car. Put all of the stock stuff in first, you can upgrade and build later.
If you use the stock ECU for now, you will run just fine. With that, you can add a FMIC, some larger secondary injectors, a SAFC and boost controller, and make a good bit more power.
I can get it up and running and tune it easily.
So can you do the wiring? Like I said, I can get the motor bolted up and make it fit in the truck but wiring is gonna be the biggest issue for me. I dont know shit about the rotary. Im gonna go with the 13bt, I might buy it for my wife for christmas, haha. Also, you think I need to buy an entire RX-7 and not just the motor, tranny and ECU? I saw alot of listings on Ebay for "entire swaps". Ill start looking for an 87 model. I will have the car by the time I come home for good in March and thats when Ill get on the swap. With a good amount of mods to the engine, how much power can I expect to get from it? And one last question, does the 87 RX-7 have a 5 or 6 lug pattern. The truck I have has a 6 lug and the selection of rims for a 6 lug is limited so Im wanting a 5 lug conversion.
