Get a way to scan it aka aeroforce scan guage and headers. And by next size smaller pulley you mean 3.6 right

As stated, I'd scan it before anything seeing as how you dropped a pulley size w/o knowing what your KR is. These cars knock in stock trim, so dropping a pulley w/o the supporting mods can be a recipie for a new motor. These motors can make some good power on stock internals IF they are tuned for it. Just depends on how deep your pockets are and what your goals are.
