Rear End Swaps
Ok guys got a couple of questions about rear end swaps
for a 86 non turbo my gears are 4.10 right, the gtu's have 4.30 gear i think, those two rear ends can be swap right. or are all non turbo rear ends the same besides the gears

GTUs is an actual model, very rare it is like an autocross ready n/a ....good luck finding the differential, easier to find a differential from an 89-91 T2......they have a different posi then the 87-88 T2

This is confusing, so let's see if I can clarify.
Pretty much all automatics had the 3.90 gear.
Pretty much all of the manuals had the 4.10 gear
The ONLY cars that came with a 4.30 gear, that I know of, are:
88 GTU
89-90 GTUs
The 88 GTU and 89-90 GTUs are the super NA RX-7, stripped, with all the go fast goodies.
the 89-91 GTU is the base model for 89-91.

88 GTU has 4.3 ratio?
Sorry, bro. Wrong answer. No US delivered 1988 Rex's came stock with 4.3 gearing. 4.1's in all '88's except Automatics (with exception perhaps of GXL's) and the Vert.
Some thought that that S4 and S5 Jspec Rex's with Manual Tranny's had 4.3 though.

god damn i got a ******* piece of **** gxl hiding in my rollup windows and manual lock doors **** that.... hey man i still love my car
SHAUNB all na trans and diffs are swapable to your car and all turbo trans and diffs require that you get the whole turbo driveline or or or get a t2 trans clutch flywheel and an automatic driveshaft and that will connect to your na diff...As for the starter do you need a turbo starter???? anyone

You will need the Automatic N/A driveshaft or if you want to use a TII driveshaft you wil have to use the TII rear end b/c the bolt pattern is different. The reasoning for the automatic driveshaft is bc it is shorter as you will have to use a shorter driveshaft.
