Can you mount the ATTESA pump in other locations?

So here's the deal, my wife picked up an S2 AWD Stagea. Super cool, clean car. Looks like the owner in Japan went track spec as it's got some heavy modifications including Exedy twin disk, tension rods, coilovers, GTR brakes, oil cooler & a Nismo 2 way rear diff. Now, cool mods for sure. But, she is just using this as a casual daily driver.

The 2 way rear is AGGRESSIVE. It also has solid subframe bushings & poly diff bushings. So that doesn't help either. So far I've tried changing the diff fluid to the correct fluid. Even tried a little friction modifier. No help. This thing clunks, skips the tires & has some slight whine/NVH when driving. Might sound like I'm being picky, but just trying to find a better solution.

Here in the states, it's impossible to find a Stagea rear diff. No luck. I do have a 300zx non-turbo diff. Same ratio, 5 bolt axles. On the Stagea, you need both front & rear diff ratios to match. This car is a 4.083. I'd like to just swap a normal rear diff into this thing. Nothing fancy. Even open diff is fine. She's not tracking the car LOL

The difference is that the ATTESA pump mounts to the top of the rear diff. There are 3 total mounting points for the pump on top of the diff.

With all this being said, what would be the best way to go about this?

I could remove the Stagea diff & see if I could get somebody to possibly weld the 3 tabs/mounting points onto the 300zx diff so we could mount the pump on the 300zx diff.

I could swap the internals from the 300zx into the Stagea diff but this is not in my comfort zone.

Is it possible to mount the ATTESA pump to the underside of the car?

Sorry for the paragraph. Just trying to figure out how to go about this. Any help is much appreciated!

Stagea Differential - Note two top tabs, one bolt hole for ATTESA pump mounting

 

300zx Diff - No mounting tabs

Also found this mounting kit ??

Id just remove the solid subframe bushes. 
you are over complicating things. 
on a side note make sure you do some research on the skyline shed before buying from them.

So, I'm not a diff swapsies specialist, but I am pretty sure the 300zx ran an R220 not and R200 like the C34 Stagea, so I think it is of no use to you.

As you said, all you need to do is get the centre swapped in the diff you have, which might be best done by a diff specialist. The current centre is probably desirable to someone to track so an easy path might be to swap your mechanical centre for someone with a standard centre (which is a viscous LSD, and almost certainly won't have any limited left). The only thing you have to watch swapping R200 internals between diffs is that the number of splines on your car's stub axles has to match the donor car, or you need the centre+stub axles and make sure they have the same number and pattern of bolt holes as your rear axles.  You swap your current ratio onto the new centre so you don't have to worry about matching the front.

Alternatively, centres like the Nismo pro are much gentler (and have adjustable "tightness") so you could buy on of those from somewhere like Jesse Streeter or Nengun (noting it may cost you 1234% extra in tariffs by the time it lands)

Pay diff/trans workshop to do this.

Nope. Z32 turbo ran R230 with 6 bolt GTR style axles. All other Z32 were R200. Basically same same as other R32 stuff. All were a viscous waste of space.
