im going to be using the t2 engine and tranny in my rx3, i was planning on using a 83 gsl rear end ,do i need to take the t2 drive shaft and have it modded to fit the gsl rear end or is it cheaper to just get a custom driveshaft made?

 

you'll need a custom drive shaft no matter which way you go. the spline on the gsl wont match the t2 tranny. Youll need a yoke from the t2 tranny and have it made to fit what ever rear end your going with. Also you cant use the rx3 drive shaft on the gsl rear end, the flange wont match.

Heads up on the tranny there's a few issue that I came accross with when using the t2 tranny, one is the tranny is longer that means the shifter is pretty much next to the parking bake handle. The way to get around this is to shorten the tail end "13btnos" explained how you can shorten your tail section I also posted some pictures on how it looks after I had shorten the tail section. The other is the tranny mount, you'll have to fab something to mount the tranny. I made a new mount using the t2 rubber bushing. and last (ok 3 issue) is the tunnel, it wont fit the tunnel with out shaving the two bolt pilars on both side. What I've done is shave the pilar and weld a new plate so that its strong enough to hold the tranny when bolted in.

hope this help

 

Yes it will. 81-83.5 GSL only. In fact, you can install the stock RX-3 diffy flange on the GSL. Keep in mind that Im only referring to those with RX-3 SP driveshaft (short pinion shaft). Non SP version has long-pinion so the driveshaft needs to be extended.

 

Right you are about the short pinion. no argument there.

 

**** so a 84 gsl rear end wont work?


it needs to be 83 ?

 

mid-83 to 85 came with larger axles so it wont work. What you need is an 81-83.5 GSL 3rd member. The axles are the same as the RX-3 and RX-2.

 

alright, damb i had i mint 84 gsl for less than a grand i was going to buy

 

I might have an extra small axle 3rd member (LSD). I will let ya know.
