Ok good, i got the LSD, are bigger numbers better? Do they sell any aftermarket ones??

Well, the bigger numbers normally give you bigger accleration, but you lose top speed in each gear. Also, there are aftermarket ones...KAAZ makes very nice high quality ones that will drop your 1/4mile time an easy second or more. They are about $700 to $800 though. Are you sure that the GTUs was the only 4.3? I could have sworn that 89+ T2s had them too! Oh well...

you can get an after market LSD like the kaaz but that won't change the ring and pinion. you can get a 4.33 , 4.77 whatever you want the higher the ring and pinion the better the acceleration but lower top speed

Here in America the 4.33 was only available in the very rare GTUs. Just about all 5 speeds have 4.10, except the 88 vert, they put the 3.909 in there. The 3.909 is what came in the auto :frown:

So the Kazz one isn't better than 4.1?

Well according to Rx-7.com only the turboII in Japan had the same 4.30 as the GTUs in US. But they are saying its your final Drive gear, not your differential, the last gear in the tranny, I'm not saying u guys are wrong, but what wrong here? And also how would i put that in my tranny, i know they are extremely hard to work on. ??? I think there is also a fluke on this page too, NON-Turbo top ends??? :newlaugh: i wish.... https://www.nopistons.com/forums/pub...>/rolleyes.gif Rx7.com

you are getting confused here. the ring and pinion is in the differential in the rear of the car. this has nothing to do with the transmission. final drive gear aka ring and pinion in the differential.
