I realize this thread refers to the R&P/final drive.
The actual diff itself is interchangeable, correct? I've been told it is, but am looking for those who have actually done it. thanks.

Interesting. I've wondered about putting a 4.3 in myself, and the 4.44 might be an interesting swap as well. I think the 4.77 gears would be way too short. Though at 500+ HP the stock 4.1 might be just as well. So many choices. If the rx8 guys want our 4.1 for gas mileage then might be able to find some direct trades. could be a cost effective way to get new gearing.

Folks reading this thread may find this of interest.
Several model years of the Kia Sportage have Mazda 4.77 gears in the front diff.

Of note to folks that want > 4.77:
Aftermarket Sportage gears are available in 4.875, 5.25 and 5.38

These are 7" ring gears and the FD uses an 8" ring gear.
It seems reasonable though that there are other cars using R&P in the correct size for an FD, and possibly desirable gear ratios.

So I bought a complete rear end from a automatic 2004 RX8 to use the gears and bearings, I wanted to try the 4.30 gears that someone said in this thread came in the automatic rx8s. So I just took it apart and counted the teeth and its a 4.44, and I just called and verified it was a automatic, so this sucks I wanted the 4.30 gears and dont think I want the 4.44 gears for drag racing. I also bought it cause I am pretty sure my pinion bearings are bad cause it makes a loud noise so I was gonna use the bearings from it too.

So... I'm not disputing whether the Rx8 and FD r&p's are interchangable. Several people stating they are.
So... my question is: Is the FD 7" or 8"? Because both the FD and Rx8 MUST be the same size for this to work, hence they are both either 7, or both 8. I suppose it doesnt really matter... I'm just curious.
Anyone got one sitting outside of the case and care to measure? Measuring either one should be sufficient for both since they are interchangable.

I have an RX8 diff assembly in a box in the garage, I will measure it when I can get back out there. ( have work to do here first)
The RX7 diff case will get cracked open real soon now, it's sitting on a tranny jack.
The RX8 diff with 4.44 gears will be for sale BTW.
Bought 4.77 gears and Carbonetics diff instead.
