I know it has been discussed before, but no one has really made any progress with this idea. I've been boiling the idea in my brain about some possible ideas. Something that struck me as a sick upgrade for our axles are corvette style axles.

then I started thinking, well why not just find a way to swap the DANA60 out of a C4 Vette. Stock torque numbers of the C4 are ~330, you could practically throw anything at it. And I mean, have a look at the pictures, with a spare subframe and some metal working time, 2 brackets could possibly be fabbed up to fit back there, with custom axles welded onto the gutted part of our CV joints and a new yolk.

The axles are mini drive shafts, imagine what they would hold?

(not all pics are of c4, but corvette subframes are present)










(older gen vette diff)





I know Pituala was working on something a long time ago, but I never saw an update. If memory serves, it was a ford or Lincoln IRS diff. anyone know?

I don't know. But I do know that would be a sick upgrade! What would be the cherry on the cake, would be to put an LS1 in the same car. Good lord if someone does this I want vids for sure.

With any swap you should also consider the gearing. Just fabricate a custom cradle to mount it to the MK2.

Good for you Jamie, I look forward to seeing you results. After destroying two stock diffs over the years with just slightly modded 5Ms I know this is a weak point. Then again I usually do really pound my daily drivers hard whether it be a city or country roads to the dismay of the local authorities.

Pretty much any IRS diff will work, but anything which isn't an MA61/MX73/RA65 diff will require custom mounting and driveshafts.

Personally I'd go for a MkIV B-series diff, but that's mostly because I want the 3.2:1 ratio.

Nice, I'll look into that too as an option. What did you end up running on your car anyways? Its been a while since I read your build thread

This would be absolutely awesome. My goal is to make my car completely bullet-proof one day, and this would be absolutely necissary. I see no reason why it wouldn't work.

I've been thinking about doing a swap like this recently but was thinking more along the lines of an S13 240sx diff and rear subframe. The R200 diff will take a hell of a lot more abuse than a toyota F series or even G series diff. There's a pretty wide array of readily available coilovers and adjustable suspension parts and they're pretty straightforward to adjust unlike some other multilink rear suspension setups. And as far as parts cars go to source a subframe and suspension from they're a dime a dozen.

you want to do subframe swap? its too big to fit under the car. did you consider this?

Almost anything that was once in a domestic vehicle will require some sheet metal hacking or your going to encounter ground clearance issues. A Dana60 is a 9.75" R&P, so a full 2 inches larger than ours. To make brackets and mount to our stock points will sit it much lower than our 7.5". To raise it up is going to require sheet metal cutting.

My point of view on it is once you start cutting, you might as well go straight axle and mini tub.

I'm down 100% with Norbie, the B series is 8" and can easily fit into the car. Making brackets will not be to hard. Its would just need new yoke or drive shaft and new axles. MKIV guys toss 1000+hp at these things when coupled with a TRD LSD they hold fairly strong.
I have an SC300 rear cross member and diff setup, which is the same as a MKIV NA but 10x cheaper to get. If I ever do get to the point of doing the work, then its just a simple diff swap away from handling big power.

The thought did cross my mind. I'm not exactly new to the concept of making things fit. I'm a machinist and have done a decent amount of welding and custom work on my other cars. I would expect to need to do some pretty heavy work to fit a Nissan multi-link IRS setup in my '85 Cressida but it would have advantages. I'd probably end up just stealing the hubs, control arms, diff, axles and geometry, then fab up my own subframe from there. It wouldn't be a weekend project, but with enough time and effort anything is possible.

I know this is mostly irs stuff, but I'm seriously thinking about a ford 7.5 with a locker or lsd. the '92-'97 or so mustangs are very close to the same width, and the tires are even pretty much the same diameter. plus they are common and have lots of aftermarket support.
the only thing is I would have to do a front 5 bolt swap anyway(for that generation mustang), but I want to anyways.

I would go big 8.8 or bulletproof 9", but I'm trying to keep the weight down.

the MK2 is IRS, mustangs are live axle.

subaru diffs are just as fragile as our cars
