Are any of you guys running 164/175mm crank pulleywith factory ecu. What I am wondering is whether there have been any fuel issues once an oversize pulley has been fitted to drive the SC. I am aware that the IC will need to be improved to use these pulleys but if you guys had any problems with fuel how did you fix them? Advice from someone that has actually done this mod would be appreciated.

Factory management can handle up to 14-15psi on the MAP sensor versions, as the MAP sensor is a 2-bar type.

cooling is at its limits with the 164mm pulley, and with the 175mm pulley a cooler upgrade is required.

if you have an AFM type GZE, i really dont know what the factory management can handle.

Mr mr2 used to lean out down low with the big pulley, but, was fine up higher in the rev range.
