250mm 300zx Turbo Clutch on S13 redtop SR20DET

Anyone know of this? Has anyone tried this. I googled and searched the sh*t out of it. Also did quite a bit of research.
Was just curious if anyone has done this or if anyone knows of somebody who has done this.

EDIT: POSTING THIS FOR FUTURE REFERENCE AND FOR THOSE INTERESTED:

THE FIRST and most obvious problem you run into when trying to bolt the 300zx TT p/pl to an s13 redtop SR flywheel is NONE of the bolt holes line up. The SR flywheel's bolt holes are spaced smaller/in a smaller diameter. The 300zx TT p/pl bolt holes are in all the right spots, but are spaced farther out/ in a bigger diameter.
You would have to drill and tap NINE new bolt holes into your S13 redtop flywheel to bolt on the 300zx TT P/PL. I also noticed.... Even if you are equipped to handle this and DO decide to drill and tap, the holes would be REALLY close to the edge of the flywheel. Leaving little material on the outside radius'es of each bolt. So I would probably question strength/integrity. I do think, however, that if you did a perfect job, you would be okay. Just something to keep in mind..

THE SECOND problem that people have mentioned (I have not verified this myself) is that the 300zx TT P/PL is too bulky and will rub/contact the bellhousing of an SR20DET, preventing you from mounting up the transmission.
After comparing a pressure plate that came on my redtop S13 SR to a pressure plate for the 300zx, I noticed added material between the wings. The SR's P/PL does not have this added material so I am assuming that is where the problem lies.
Pictures referring to said problem:

Old Redtop S13 SR Pressure Plate:


New Z32 300zx TT 250mm Pressure Plate:


Again take notice of the ears or the pressure plates. Again, notice the added material/bulkiness of the 300zx P/PL compared to the SR's.
I believe you could remove the material and be fine/okay. But on that same note, I think the exact same amount of material better be removed from each ear perfectly so as not to throw the P/PL out of balance.


THE HYPOTHETICAL SOLUTIONS:

Problem #1 is easily solved with a custom flywheel. The TT Z32's P/PL external diameter measured 11.875". So I'd say a 12" diameter flywheel would be perfect.

Problem #2 is not so easily solved. I think you'd either:
A) Have to remove some material from the 300zx's P/PL
or
B) Remove/grind some material from the SR20DET's bellhousing to gain clearance to run the TT Z32's P/PL.
or
C) and maybe the best option --> A little bit of both A and B.

the 300ZX pressure plate is too bulky and will hit the SR20DET transmission bell housing. if you want to run a 250mm clutch disk we have the JWT Flywheels that have both the OE SR20DET and VQ35 clutch pattern drilled on the flywheel along with the 250mm friction plate. so you'd be able to run any clutch made for 03-06 Z33. we have the flywheels ready to ship if you are interested.

NOO shit!? That SUCKS... Any way of modifying the bellhousing?
The reason I am reluctant to your option is the cost for a '91 300zx TT clutch kit and a 350z clutch kit is night and day.
