13b engine,
13b turbo
13b tt
Of the internal parts, rotors, rotor housing and side housings. Are any of these interchangeable?

some things are somethings aren't.

if you do change rotors u have to change the counter weight/flywheel.

The big changes are compression ratios (for rotors).

side housings between na/turbo are quite different (6 port and 4port) and are not interchangeable.

housings have different spark plug spacing but i think it is negligable (trailing-emissions?).

basically it's not a straight forward as a direct swap.

post a combination and some of the other guys could tell you if it will work.

I have a 93 Rx7 and have the engine apart. I am waiting on a manual and some micrometers and the like to do some measurements. I likely will have the engine built out side but I would still like to explore a bit. I was going to buy James Paventi's motor/car but I missed it to someone else. That was too bad but shi* happens. The machining and part fitting is where everything is so critical. I am a piston guy and with a rotary the cylinder walls are laid out like a pie tin, flat and large. truly a rocket engine. I am so shocked to see 300 horse power come out of one of these so easy.. Managing the turbos, timing and fuel mixture is where you can turn an engine into trash. I also would like to go ceramic again I would like to be 20 again. John
