After reading these, and all the other supra, forums for a couple years, it seems that the OBX are the choice. You'll have to splice in longer wires for the 02 sensor (no big deal).
I just talked to a guy last week that was building a street racer, and he told me he installed a little box that eliminated the 02 sensor. He said the box simulated the signal of a perfect fuel mixture. It was fairly cheap. He and his dad have built many streetrods, and he has been in the parts business for a long time.
I will try to find out more and let you know.
