13b on 12a tranny?
I have an 85 gsl rx7 i just recently bought and earlier 13b motor. from what i was told it came off a REPU. Ive already got the gsl-se oil pan and wanted to know does the motor just go in to the stock 12a tranny? and can i use the 12a flywheel? or a second gen? (flywheel i have one sitting around)
thank you for reading

I'm not sure about the engine/tranny I think it should bolt right up tho. What I AM sure on is that you can't use the 12a flywheel on the 13b regardless of size because the rear counterweight is cast into the flywheel.

I got a tranny with the motor but it looks just like the one I already have on the car. About the flywheel I had a feeling. Thanks. I know the 13b is an older model 13b cuz it has an oldschool Mazda imprint on the housing. Any 13b flywheel should work?

It was rebuild before and then just sat for awhile. My friend rebuilds these motors. From what he saw he said it had GSL-SE. Rotors it also had a street port and the guy I bought it from mention a half brige port. We also where able to check the compression on the motor sound strong. So that's what I know. And I'm just trying to get this thing going. Thanks

If the internals (rotors) are from a GSLSE then you can use the 84-85 N/A flywheel but if it really does have a bridge port it would be a smart idea to go light weight for your flywheel. How did you check the compression, in the car or out?

My friend would rotate the rotors. By turning the bug bolt in the front of the motor and should good compression. And thank you guys for the help/info on the flywheel. I got a better idea of what to do.
