I finally pulled the trigger on a new starter motor for the 1GRFE V6 in the 120 series.
Settled on a Bosch BXD039N. Now this baby cranks! @ 2kw compaired to the Denso original boasting 1.6kw.
Had some conflicting info as to wether this was a direct replacement.
The bosch is a bloody lot heftier unit, and a very precise fit.
The main battery cable mounted up to the solinoid lug without to much hassle, but the ignition wire plug is in a lower location on the starter so this wire had to be extended.
