I suggest you put a 2zz into it. 12years more modern and not too hard to install into the aw11. You could get it completely installed for under 4 grand.

A 2zz would be an awesome motor in these cars, I have not seen much written up on the subject tho.

Silvertops, smallports and late gze all have the same rods, so they are fine for boost. The comp is why you cant get away with running much boost.

This is what I have heard as well. I think if I was to be serious about boosting the motor id drop the compression and get better pistons with an aftermarket ECU to save on hassles down the track.
