Hey Greg... the diff carrier you’re using is from a S4 (86-88) Rx7. The S5 (89-91) carriers are 2lbs heavier. The S5 has thicker webbing across the "beam" .475 vs .320 for the S4. The S5 also has been triangulated in the beam area as well as having the lower web of the beam merge with the output shaft saddle. All in all the S5 is a beefier unit.

Hi cmoore74, does it matter if the diff is from N/A or turbo, are they all interchangeable?
@benmarsh92364 жыл бұрын
I'm just talking about the carrier, not the whole diff.
@cmoore744 жыл бұрын
Ben Marsh the turbo diff carrier will not work as the case itself is larger and the bolt holes don’t line up to the diff casing. I have two extra carriers if you’re interested. We could discuss over PM.

Edit: I rebuild automatic gearboxes all day and you did a good install on that drive shaft seal. Perfectly done, you got RTV on the inside of the bolt holes too which is missed out by a lot of people.

They built these diffs to serve the 120-140hp these Miatas came with,and they meant it. I've read mixed reactions to the rx7 diff. Some wrote they were great to supposedly like 500hp,others claim 300hp or more and it'll explode. I'm thinking if anyone is looking for more strength on a budget,the rx7 is the way to go. Me personally,I'd do either the heavy 8.8 irs or the lighter getrag. Both have plus's and minuses. 8.8 it's,is heavy but are everywhere pretty cheap. Buku parts and ring sizes are available. The getrag,it's much lighter than the 8.8,but no where near the aftermarket support and ring gears.

Hey there, I've been watching your video for long time and a big fan. I have a few questions wondering you could answer cause I'm using cd009 transmission. 1st were you making over 450 to 500hp when you installed the rx7 diff if so do you think reinforcing the diff bracket would help? 2nd i saw you upgraded the rx7 diff to a Cadillac diff and it solved a lot of issues you were having. Do you think it was necessary cause you didn't explain if the rx7 diff was a temporally fix or if it broke as well? My opinion are staying with rx7, or ford 8.8, cadilic o 350z? The car will be making 500hp and wanted tour input. Thank you.
