I was wondering which trannys of rx7 from any generation have LSD? if u cud please list them, and i was also wondering if the se tranny is the same as the NA/FC tranny?

 

This is not the Honda board...


7s dont have 'LSD' trannys 7s are RWD

 

To answer your question, albeit with a caveat, the 81-85 GSL cars had a LSD DIFFERENTIAL, not tranny. Look for cars with rear disk brakes, as they came with the LSD. THe '79 to '80 cars did not have rear discs or LSD offered. The GSL-SE transmission is identical to the earlier 12A cars, except for taller 5th gearing. The FC tranny is a different animal altogether, built stronger than the earlier ones, obviously because of the higher output of the FC 13B's.

 

On RWD cars the 'LSD' comes separate from the tranny. the D in LSD stands for differential.... that is where it is located. FWD cars have integrated differential and tranny. So in the RX-7 there is a differential (in the center of the rear axle) aslo known as the third member.

the GSL and SE trim levels of Gen I have LSD's, as do serveral Gen II's (ask them, I don't follow what has what in Gen II's) and all of Gen III's.

 

Uhh haha.......... my bad, i know that they dont have Limited Slip differential trannies i meant diffs just by them selves, it was my mistake for saying tranies with lsd im out of it today.i meant trannies becuz i was wondering which were different like the FC and so on. so thank u Moses and fatboy for actually answering my questions

 

Did GSL's come with LSD as a standard or was it a option?

 

The GSL came with LSD standard. BTW the GSL-SE transmission is not identical to the 12a cars. The fifth gear is different and also the SE trans. has a vent in the bell housing.

 

My GSL is the first car Ive had that had a LSD and is just seems to make all the diference. I love it.

 

Here's a list of final drive ratios. I know what FC models had LSD, but I don't remember where that info is. If I find it, I'll post it.
