Yeh, i'd back the TO4E. Thats just from what i've read out of an article Reg Reimer produced:
Over the past few months I have Dyno tested three different Turbos on the Supra GTE. See the Dynojet printouts in this article. The best turbo tested to date has been the HKS Sport Turbo Upgrade turbo kit for the 7M-GTE. This Turbo spools very fast and has a very wide power band, about 3300 rpm to well past red line if required. The Dyno runs show this turbo still pulling hard at 6500 rpm {see printout below}. This HKS turbo produced 339 HP and 398 ft/lbs of torque at the rear wheels. This turbo required an upgraded clutch to hold the power. The clutch I installed when I put the 7M-GTE engine in would not hold any more than 300 HP and 340 ft/lbs of torque at the wheels
