If you have a track car a 4.3 is probably essential for most tracks

The KAAZ is amazing on the track. Helps traction AND cornering

I really want to swap my 4.3 with KAAZ for a 3.9 with KAAZ or 3.9 with Cusco.

Probably impossible but you never know

Not really interested in selling the 4.3 Kaaz outright as the Kaaz alone is $1500 plus fitting.

But I would listen to offers starting with a 2 and its not $200

If a jdm ser7 comes with a 3.9 then i have the gear set for you. I put a 4.77 re amemiya instead with my kaaz. You can have for free, just freight from Wa. Then you could swap out for your 4.3(Keep spare or sell) Around $500 to build, just a thought...

Unless it was an auto, in the S7, it won't be 3.9. Have the rebuild kit for a bathurst 3.9, cwp bolts, front and side seals, crush tube - no bearings.....$50....was sorta saving on the off chance a housing turned up, but won't be happening anytime soon I suspect. The the last diff was somewhere in the $300 range to build by a well known rotary racer and ex Borg Warner guy. Should be right up Terry's alley too.

Thanks Bill. Any chance you could take it to Mortdale? Will be there in the next week.

It's all over there....just have to pull half the place apart and perform a few double pikes and somersault to find it! If bigfella can't come through, have a 3.9 ratio too - again, not sure where it is, but with FOSC seemingly dead and Trackcorp a bit rich for the blood, not sure there'll ever be a need for it.

I am about to strip this out and replace the CW and P with a 3.7 or 3.9

If you want it now is the time
