hi
i wonder if there are variations in crank pulley sizes ?
it must be pulley sizes , either on the blower or the crank shaft
thats the only real way boost can be that much different ?
very interesting ,
maybe someone else out there can shed some light on this ?

AFAIK (and confirmed from Lexus parts technicians FWIW) all early 1UZ's had a 140mm crank dampner.
I did also confirm that the early 2UZ's, have a 157mm.
I don't have any information on the later 1/2/3UZ's VVTi motors.
