My new baby.. 13b clutch in 12a?
I know that all the rotory bell housings are similar in many ways. I was wondering if a 1988 TII Clutch would work on my new 85 GS? Would it throw off the weight/balance? Or are the clutches the same.
Also I have been reading over the faqs, what modifications I should do to it for reliability purposes. Coming from a fuel injected 13b to a carb feels completely different . But I love the car so much already lol.

Those are just the sizes for the N/A rotaries.
The TII clutch is bigger still,it wont work....and its not needed anyways.The 225MM clutch is plenty strong for just about any N/A rotary around.If the stocker cant hold,then upgrade to a performance 225MM clutch.
The engine balance is determined by the flywheel or rear counterweight.The clutch assembely itself is neutrally balanced.The TII flywheel would physically bolt up to your engine,but it would not balance correctly because of differences in the counterwieghts/rotors.

So to answer your question, no you would not be able to use a TII clutch without changing to a TII trans which is not straight forward.
The bellhousings are larger, bolt pattern the same. the starters are different and mount differently and some other mods are needed.
Your better off buying a good quality street/strip clutch for you year and model. Unless your up for the challenge.
The only difference in mods is the intake choice. The header is a header whether it is a 13b or a 12a just go with a quality system.
As far as carb/intakes. I have found good luck with the mikunis and others swear by the webers. The webers are easier to get and generally produce more Hp.
If you want a good quality carb with the best reliabilty then a sterling carb might be your choice. I have heard nothing but excellent things about his carbs.
Other than a lightened steel flywheel, upgrade of wires and maybe coils.
electric fan is a good upgrade to lessen the Hp draw. Just make sure it is a High Cfm onelike a fiero, Taurus or black magic. Be sure and install a t-stat control for it.

Just to be clear, I can buy an aftermarket clutch for a 86-88 NA rx7 and it would bolt up to my 12a without any problems? Because I currently am running a southbend clutch on my tII and love it, they make a clutch for the 86-88 NA engine as well and would like to use their setup if it would bolt on with no bad sides.

Thanks a mil. Are there any good books or sites for learning about carbs? I been searching on here about the different types and what not, but I think I should try to learn the basics behind it first before modifying.

I believe that weber has there own book on their carbs. As far as mikuni they had their installation manual but is no longer available. Someone may have one and be able to make copies. Sterling does his own thing.
You will find more info on this site concerning the carbs and their usages then any book that is out there though.
Sterlings carbs are a straigtht bolt and run situation as set up per motor. Mikunis and webers may need fine tuning but all the info is on this forum.
