If anyone is experience in general with transmission swaps etc, feel free to critique as I only obtained this through reading and the materials that cover this info are few and far between, so I have just deduced some of the info from reading alone, and I am sure there is a hiccup or two in what I said. I think all the above parts minus the bellhousing, mount, and shifter relocation would transfer over no? T56 is also 26 spline and I dont see why the clutch wouldnt work, maybe the throwout bearing would need to be a different part number but otherwise I dont see any issues? Now there is also the option of a t56 with straight cut gears or dog engagement. Trans mount - easy for a competent fabricator Shifter relocation - Gforce offers their "road race" shifter with chromoly shift rods, and you can just custom make a bracket to move it, but I know gforce offers different adapter plate sizes but unknown on the supra specific dimensions needed. driveshaft - decent driveshaft shop can do this
32 spline yoke for output shaft- well you can find these all day - mark williams, spicer, strange, etc. Really - Im about to drag my iroc vert out of mothballs and get her up (hopefully) in time for summer. any 7.25" clutch with 1-1/8'' x 26 spline configuration - RAM, quartermaster, Tilton, ACE, and the list goes on - You can buy used nascar tilton triple disc clutches for sub $1000 in good condition. Transmissions and Drivetrain - 600 hp G-force T-5. xcessive manufacturing seems to make a flywheel adapter for the 2jz to 7.25 clutches bellhousing (no need to use factory v160 bellhousing) RTS sells this
