Well I'm currious if my starter motor will work on the engine.

I have a 12a 5spd tranny hooked up to a 86 13b block.

The starter is from an 89 motor.

It seems to bolt up fine... but I havent tried it yet.

Will this combo work or will I need an FB starter?

Try it and find out!

There are two different 1st-gen starters, one with an 8-tooth gear and one with an 11-tooth gear. Since the flywheel diameters and starter cases are identical, the difference must be in the transmission case. FWIW my '80 had an 8-tooth, my '85 has an 11-tooth, and I don't know which year brought the change.

I think it may work. My friend's 87 GXL's starter screwed up, and I gave him the one from my GSL-SE, and it worked. (I have a TII starter now)

Then again, they were both 13B's with the larger flywheels than the 12A cars...

An 83+ 12A would have the same size flywheel too.

All '74-up N/A have the same size flywheel.

I've got an RX4 starter in my 7 right now.

What year RX-7?

Specifically, what year transmission?

would the 12a tranny bolt up to the t II 13b?

peejay

Yes it would.

The T2 flywheel won't fit in the N/A bellhousing, though. You'd need to get an N/A flywheel for it (use stock flywheel from same year, or get a N/A lightweight flywheel).

Make sure to have a good stock of transmissions on hand. The N/A RX-7 trannies are fairly weak, especially the later ones which have bearing problems and fine-pitch gears.

ok good, i just wasnt sure because of the 12a tranny if the 89 starter would reach the flywheel from the 86.
