Went to the Track last time and my diff started to whine. Went to the track last night and my 2nd run went Boom. I was expecting the diff wouldn't last long.

My question is... Will the RX-8 pumpkin drop right in the FD3S? There is one for sale but Im not sure if its a direct bolt on. I've read that other people take out R/P and put into FD3S Diff but haven't heard of a direct swap.

I'm also thinking of rebuilding it myself... 4.3 gears with Kaaz 2way lsd. Kinda expensive though. What exact tools do I need? Parts?

Anybody who has experience with diffs please help.
