I have a mate parting out a R33 in nth qld if anyone is looking for bits.

Hey Box ask him if he still has the diff will you please ?
And if its a manual or an auto. I happened to score a 3.5 diff for mine but wouldn't mind a spare.:MECOOL:

There are heaps of them Rog. The only way to be sure is to count the rotations. Earlier thread helped me sort out mine: http://www.clubcobra.com/forums/show...rential+ratios

Merv the smart way is to pull the back cover off and see what's stamped on the crown wheel-the Japs ALWAYS stamp the crown wheel with the number of teeth on crown wheel AND pinion. It also helps that you can have a quick look at the internals to make sure your not buying a dud too :MECOOL:

True Rog Mine was 4:1 after counting revolutions of the drive shaft relative to the wheels. Can live with that for the time being.

Good idea to list out the different ratios...

R32 GTR is 4.11

We used a GTR diff as it has a couple of advantages over the standard GTS-T, clutch LSD, stronger driveshafts, aluminium uprights etc.

Purchased a spare centre when we could find one for a reasonable price as the downside is that they are much more rare than the GTS-T.

We also used R32 aluminium front uprights, brakes etc.
