Did all the FC models come with a 4.1 LSD except for the convertable?

 

Only the following USA model 2nd gen RX-7s had a LSD from the factory:
86-88 GXL
87-91 T2
88 GTU
89-90 GTUs (however not the 89-90 GTU)

The 2nd Generation FAQ at the top of the forum has more information.

 

also gxl autos have a 3.9 LSD not 4.1. All Autos had the 3.9

 

GTUs was 4.30.

 

thanks but that wasnt the question.


is the 4.1 prefered for the turbo II?

 

The 4.1 is preferred over the 3.9, generally. But the 4.3 is rarer, and will net better acceleration. Downside is it's hard to find, and if you're doing a lot of highway driving it might bring your revs up where you don't want them to be at for cruising speed.
