62mm Throttle Body or 8.25 Rear Differential Swap.

[streetxj]

Yes, the 91+ XJ's came with a 8.25 unless ABS was equipped. Those had the Turdy5.
Since yours is a 96. before you swap a LSD carrier or locker, make sure you find out whether its 27 or 29 spline. Regardless, when you pull the cover I recommend installing lube locker gasket. Well worth the money and not having to spend time cleaning up gasket crap.
If you want it larger, I believe he will make up to a 65mm for no extra charge. Just have to let him know.

Oh okay. Thanks for clarifying that. Mine doesn't have ABS. Since mine is a 96', it's probably a 27 spline. The build date of my jeep is April 13, 1996. I'm staying with 62mm for the throttlebody since it matches the throttle bore of the intake manifold which is 62mm. Any bigger than that, then it will cause turbulence in the air flow due to having a ledge around the base of the throttle body. The bigger, the worse it is. Usually they enlarge the manifold throttle bore and use even larger throttle bodies for strokers due to larger displacement.

Ive bored my own TBs with great success to 60mm below the plate.....also sold a bunch of them and everyone likes the performance improvement.

I've just installed a 62mm throttle body. Thanks for the heads-up.

Disconnect your battery, and reconnect to let the heep relearn with the new TB.
