thanks for the info looking for around 12 to 14 psi going to tuck blow off on inlet somewhere outa sight where do i find these crank pulleys

yep - mines running the os crank pulley @11psi

Due to the electric clutch making it fairly hard to swap out the pulley on the charger, its much more common for 4AGZE owners to swap the crank pulley for a larger diameter one, which has the same effect as putting a smaller one on the charger. I used to have a GZE in my corolla, and back in those days the 175mm crank pulley made by Nevo was all the rage, the kit was pretty cheap too.

Its a complete replacement pulley, but only the splines for the charger belt are oversized.
From a 175mm crank pulley, you can expect about 14~ psi of boost, which is what most people Ive known run. Makes a fair bit of difference!

HTH

Great motor and awesome little s/c as well. I love how the clutch for the blower pulley is electric - means that a switch can be added to the circuit... Perfect to watch Commodore driver's jaws drop as you flick it and wave as you sail past lol
