I searched and read some different threads trying to pretain to my question. I DID find some interesting facts about how the tranny's blow up. but nothing really useful about the tranny swap i am thinking about doing. Basically, i see that the flywheel's are compatible from fd's-fc's. just need the corresponding counterweight. so, i would ASSUME that the trannys are compatible. but, i wasnt sure if the mounting bolts matched up, and the tranny shaft being in the correct place for the shift **** to pop through the stock '88 Turbo (which is what it would be going into) shifter bezel. sorry if i wasted your time and such. its just my tranny has got some interesting, "kinks" (theres this "notch" between 1st and 2nd gear. its like i have to go around a little bulge to shift from 1st to 2nd. and my 5th gear synchro is gone. so, needless to say, i know how to double-clutch upshifting!!) and i like how the fd gearing is a bit longer.

Thanks alot guys,
Ryan.

 

bell housing bolts are are not the same and i dont think the mount is the same either. besides, i read the FD tranny is nearly identical to the TII tranny.

 

From what most say on here. Internally they're basically the same. It's not a direct swap because the FD uses a pull type clutch instead of the push type of the FC. Also I saw it mentioned that the input shaft is shorter on the FD so even if you swap the Bellhousing it may still have problems matching up.May not be worth the trouble to make it work.

 

Why is it that everyone thinks because of its an "FD" its better than whats on your "FC". I mean **** they are swapping out the rear ends for the FC clutch type. An FD transmission is NOT and upgrade for a TII.

 

Tii transmissions are the best just go with that, find one in decent condition and have it rebuilt or try to just find a good one in general, they take quite a beating it seems never heard any complaints about them, just N/a trans like mine ( peice of Sh!+)

 

Actually thats a great assumption. Why? Becuase mazda had that much more time for R&D on a very similar engine! Thats why the FD intake is better, the actual engine is stronger etc cause its newer technology. From complex things like that, to the friggen radiator cap housing, most parts ARE better on a newer car of the same series, ie rx7.

 

From Brian Long's RX-7: Mazda Rotary Engine Sportscar
"The five-speed transmission was a development of the Type R unit, and feature double-cone synchronizers on the lower gears to enable the 'box to handle the engine's extra torque and inprove change qualify.'"

So it does appear to be "better," but do a little research on how people who's FCs have more power/torque than the stock FD, to see how their trannys hold up. I imagine there would also be a premium to pay for the FD tranny.

 

FD owner bitch about the 2nd to 5th gear shift.
They claim the shift pattern is too close and allows you to do this not on purpose.
Try and do this at WOT at redline, and you're pretty much going to blow up 5th gear.

With that said and done, the FD gear box is basically the same as the Kouki FC turbo gear box.
Ratios are the same.
With the exception of better synchros and maybe some miscellaneous parts, it's all the same.

The bell housing is SHORTER on the FD tranny - this means you cannot swap them not without going to the FD pull-type clutch.

lol man I dont need to ask anyone, I have 1st hand expierence. I for sure am making much more power an a stock FD. My transmission is perfectly fine. Plus that **** you quoted is probably not a transmission that comes on some regular FD.
