Hello, I recently purchased a mazda rx7 1983 12a and i'm new to the world of rotari engines. My 12a is not in it's best shape and I don't want to spend money on this engine (lack of power). I thought it would be nice to swap in a sr20det redtop in it to keep its a good compromise between weight distribution, power and price (rotari parts are hard to find here). I already started to look for some information to do it but if someone has some clear instructions or parts list it would be great if you could share it here!

Thanks alot and don't kill me for putting a piston engine in a rx7!

 

there is someone on the 1st gen rx7 group on facebook who already has one up and running, still needs to finish it i think but it works. you might want to join and find him.

I'm doing a 2jz. What questions do you have?

 

Well, it's my first swap and i'm just trying to get as much information as possible before the swap. For now, my plan was to order an sr20 engine/tranny and wiring. To sit the motor I found that the simple way to do it was to get a 240sx crossmember and engine mounts, i'm going to do some modifications to them for the shifter to get exactely at the same place as the original one and the engine should sit at 1-2inch from the firewall leaving me enough room for the rad and intercooler.

I was trying to find out if the stock headers and piping from the 240 would fit in the engine bay and will the engine clear all the stock steering parts?

 

That video is my car.

Check out my youtube channel for a lot more. Its a pretty easy swap if you have a welder.
