syphon, on a US model, if you change from a auto flywheel to a manual flywheel you must also change the balance weight behind the front cover. they are different!

sorry. changing the front counter balance when going from auto to 5 sp or vice versa.

Hey,

So I just have to change the flywheel counterweight, as the flywheel weights will differ from automatic to manual.

That's understandable.

No big deal there, Thanks for the advise though.

Also, where can I find a decent clutch for the motor (I don't want to re-use the one I have). I was thinking centerforce I or II.

use an ACT they're reasonably cheap and have a good track record

ACT?

Have a link for that one?

I was just gonna trade the OEM balance, and flywheel.

Thanks,

Brendan

I just discovered that my 81-rx7 got also a 12a 6-port.the previous owner has fitted it on the car but he made it work as a 4-port.the engine came from a 1984 cosmo HB and mazda used to call it 12a\spi.if you gonna make it work properly as a 6-port it produces 130hp(all stock).
