I am not, but I see no issues with that. Thats an 18.75% OD for the record.

At 6,700 rpm, the factory blower spins at approx. 21,440 rpm.
with a 9.5" lower, that will increase approx. 18.75% or 25,460 rpm. Your results will vary based on elevation and other mods... but you should be in the 11-12psi range. What else do you have done to the car?

Will be doing a 103mm TB, 5” cold air, have kooks full 2” headers green cats and kooks mufflers then the lower pulley. Or would a smaller pulley be better?

You're going to turn the blower into a furnace real quick and then power will drop considerably as the ECU pulls timing to keep the engine safe.
You're better off with Flex Fuel and a 2.3 upper. You really need some blend of E when you put a pulley on these cars.
