IF YOU HAVE THE R150 OR R151? BOX IT WONT FIT! 
and sorry there is NO bellhousing that will either (unless you cut and weld two together!)
Well... in this case "Don't raise the bridge... lower the river..."
As an example of what can be accomplished:
Pic 1: Bellhousing from a 3.0L Supra Turbo attached to an 89 Jeep AX15. The input shaft is 7.82" in length but 6.55" to the edge of the threads.
Pic 2: Toyota Supra Turbo R154 next to Jeep AX15. Input shaft is 7.25" in length but 6.65" to the edge of the threads.
It is obviously possible to swap the 91 and earlier Jeep input shaft into an R150F\R151F and use the Supra Turbo bellhousing to hook it up to the 7MGTE.

Here's a less troublesome way. Possibly less expensive too.

http://members.ozemail.com.au/~jonhel5/I learned that Marks makes an adapter to mate the R150F, and/or R151F (both with 165 mm or 6.5 inch long input shafts) to a G52/54 or W56/W58 bellhousing.
See
http://members.iinet.net.au/%7Eozrunner/AdapterR150.html . I am waiting on the Marks part number. This unit should be available in the US via Advance Adapters - Marks agent in North America.
So just take your turbo Supra 7M-GTE block, use a 5M-GE flywheel - clutch assembly - and (W58) bellhousing assembly, this adapter, and mount your trusty R151F to the engine. No more trashed G52/G54 or W56's!
