Hello I have a gtp sc 3.8 coupe and I was wondering if I wanted to change the pulley what size should I go for

hi.

you cant do anything until you read.

Put that pulley on and say hello to the mechanic or a junkyard motor and few hours of your time replacing the motor.

Are you saying changing the pulley will create problems

Yes.

If you only changed the pulley to one smaller, you will in a short time, chip a piston and need a new motor.

You have to mod safely so you can drop pulley size. Like headers, intake, plugs, then a tune with a pulley drop, while scanning to make sure it can take those mods.
