Not much to report ATM. Dennis has been up to his eyeballs with other work, but the plan is to sort out the difference in compression from bank to bank, put a cogged belt system to drive the supercharger, fabricate some dyno headers, then have another go on the dyno.
We're also preparing a 2nd 1UZ, which will have a different set of cams and should put out some some interesting numbers. This one will also have 12mm head studs, piston squirters, Lextreme rods, Ross 8.75:1 pistons, etc.
I'm tempted to keep one motor supercharged, and build the other up as a twin turbo. Except for the FMIC piping, the car won't know or care whether it's a turbo motor or a supercharged motor, as long as the intake, fuel, radiator, and exhaust pipe(s) connect in the same place.
I honestly think a turbo motor might be a little easier on the drivetrain than a supercharged motor, as it won't have such a fat torque curve. 425 ftlbs of supercharged torque from the get-go might be too much for even the Supra's mighty 6spd, whereas the turbo motor's torque should come on more linearly with boost and RPM.
We're shooting for another dyno session before Christmas.
