Engine Question
So...I'm a new owner, and I know very little about this car (as of right now). I do know that this car has a lot of miles on it, and I would like to keep it and improve it as time goes on and all that. I was wondering...about the engine. Are there any compatible engines I can put in my 1988 mazda? (for example, I had a 92 dodge stealth, and that engine, the mistubishi 3000gt and certain eclipse engines were compatible with the car). Thanks!!!!!

Will a 3rd Gen RX-7 (FD) twin turbo engine (13B-REW) fit in my 2nd gen RX-7?
The simple answer is No! The motor mounts are in different locations as well as other issues; however if you have enough time and money it can be done. Much of the project will be custom fabricating all the systems that attach to the engine such as the exhaust, intercooler setup, cooling system and wiring. A standalone EMS is almost required and it is very difficult to control the sequential turbos. Most people go to a single turbo because of this. In general this swap is not worth the time and trouble unless you plan on making more then 450 HP.

There have been many past threads covering swapping the 13B-REW into an FC:

Can I put the RX-8 engine (Renesis) in the 2nd gen?
Well, technically yes. But it is not a simple bolt-in swap. The Renesis uses different mounts, and an entirely different ECU and wiring harness. Anything can be done, but this is much more complicated then swapping any 2nd gen engine into the car. Lots of fabrication, wiring and other things must be done to support this engine. It is generally easier (and probably cheaper) to swap in the 20B three rotor, or the 13B turbo from the Turbo II.
I want to replace my rotary engine with a piston motor, what can I do?
Some people have done that, but it is generally not covered or even recommended to be brought up here in the 2nd Gen Sections, but rather in the Other Engine Section of this board. There are also other websites out there that cater to helping conversion issues.
Yes, check these links:

There are many engines you can swap into these cars. I know for sure that you can swap V8 engines such as an LS1 from a corvette or a 350 chevy. You can also swap a 4g63t from a talon with a wide block and with a bell housing from a mighty max pickup truck, the engines with bolt up to the stock transmission in an FC. I am currently putting an LS1 in mine.
