I am putting in an 8.8 in my truck! I already broke 2 rear ends and I am not even turbo yet! No more broken rear ends for me!

 

Make sure to buy quality parts for the 8.8, they can also break if you're planning to use stock parts, there's no cheap junkyard miracle unless you're planning the car show circuit or Sunday cruising lol, I remember when guys actually raced their rotary powered cars.

For the other guys trying to put a big axle rx7 rear end, don't waste your time with that, look into other options for replacements, it doesn't always have to be Mazda with Mazda

 

Yeah I actually building it up and not using any of the stock stuff. I am putting Moser 9" Axles ends on it that way I get rid of the c-clips. This will also allow me to use the bigger 9" outer bearings and run the bigger 9" axles. I am replacing the Clutch style LSD with a Torsen style LSD and buying aftermarket Axles as well. Goal is to build something stupid strong that won't break and can handle the abuse.

 

Does anyone know the exact width of the RX3 stock rear?

 

I know I'm late to the party but I just took the 3.90 FB LSD diff and installed in my RX-3 housing and bolted everything up . Stock body so no issues with width and could keep using my 15 X7 Riken Mesh with 4 X 110 bolt pattern .
