I was looking at my friends Mustang 6 speed tranny. It looks like it would fit. Does anyone know if I could put the Mustang 6 speed in my RX turbo 2?

 

My guess is that the bolt pattern doesn't match.

 

I've thought about this before with the older (Fox body?) Mustangs. Built transmissions for those things are a dime a dozen and parts are available everywhere.

Essentially you would need to machine a custom bellhousing to match the rotary, and then deal with modifying the input shaft to fit the eccentric. I have not actually looked at one but it seems to be easy work (shrink the diamater on a lathe if necessary and then cut off the excess). If the shaft is too small, use a thicker pilot bearing/bushing. Mix and match clutch parts so the RX-7 flywheel and clutch plate are used but the appropriate clutch disk is substituted. Driveshaft from any driveline shop for a few hundred dollars.

 

Aren't the input shafts hardened steel? Good luck turning that.... You'd prolly be better off buying a mustang race flywheel without the mounting holes and drilling it to bolt onto the E-shaft. (I know you can buy dodge race flywheels without the mounting holes) ~rich

 

They're not really that hard. I've ground them for various reasons before (for example making broken input shafts into clutch alignment tools) and it's easily done. A machine shop should have no trouble turning it.

 

and what's wrong with the T2 transmissions? the only real weak point in them is the synchros, i would much rather have a synchro out than a bearing or gear. 6 speeds does not mean it is better than 5 speeds.

 

Another question for one who has never driven a Mustang before. How high or low are the Stang trannies mounted. Also, how are their gear ratios?

 

You can get any gear ratio you want for these things...That's sort of the beauty in aftermarket support.

 

I thought fox stangs had swappable guts with TII trannies.


Are you sure this isn't the case?

 

What kind of money are we looking at for making a custom bellhousing?

 

Depends on your machine shop. It may be as simple as just machining a bellhousing adapter, in which case several hundred dollars. If you actually have to fabricate an entirely new bellhousing, then a lot more. It's likely possible to modify a stock bellhousing by cutting off the flange and then welding on a custom flange to fit the 13B.

 

since when did mustangs have 6 speed tranny's besides cobra's?

 

yeah, my mom owns a Mustang (V6) when she bought it, I looked up everything about the Mustang family. The 2000 Mustang Cobra R had a 6 speed, then in 03 the street legal cobras saw their first 6 speed transmissions (the only other stang to ever recieve a 6 speed). So the cobras had a six speed in 2003 and 2004. Also the 2006 Model year Shelby G.T 500 is planned for a six speed, but that's it. A 4.6 to 5.0 Liter V8 is WAY too different from a 1.3 Liter Rotary that doesn't seem like it could match up anyway. i'm not technical so I don't know if it is matchable but I mainly posted to back up tjeter's point on stangs having 6 speeds.
