What LSD Fits
Hey everyone, what Mazda LSD fits the REPU? For example will a LSD from a serirs 3 Rx7 fit? Any help would be great. Thanks.

Why don't you look into the Amigo rear-end Klaus?
You get disc brakes (nice vented ones) and keep the 6x5.5" pattern.
I'm fairly certain its the right width.
If it is, then you just grind off the suspension mounts, weld on those from the REPU in the right place, have a new yolk put on your drivaeshaft and you're in business.
I know it sounds like a lot of work but:
1) Grinding and welding (the easy part).
2) A new master cyclinder and an adjustable propoertioning valvae should run you less than $100.
3) Take some careful measurement and have a driveline shop fix up your driveshaft.
If I have the money when I get to that point, its what I'll likely do. I want the LSD and the brakes. If it were just one or the other I wouldn't bother, but the package makes it more attractive.

No money for anything right now...
...but now I'm curious about the details, Martin... like what gear options exist in those Isuzu 'ends, and how heavy-duty they are, relative to our REPU's... or not...

Gear ratios should be available on the web easily enough.
As far as strength goes its got to be at least as strong as the REPUs rearend, but they back up a V6 (I don't think the I4 comes w/ the disc brakes) so they got to be able to withstand a decent amount of torque.

The late 80's to late 90's Isuzu Rodeo and Hombre truck V6 didn't make much torque. I'd guess 180ft/lbs.
But that is MORE than what REPU makes!
I recall thre was a real short 4.56 ratio in the old Isuzus, but NO idea what year or model truck.
Gotta search the web!
