i was woundering if the pulley from the 2.2 is the same as the 2.0 sc???

 

If you mean a smaller diameter crank pulley, you don't want that on an SS/SC. It'll do more harm than good. Here's why:

#1 UD crank pulley will drive the supercharger slower. That'll hurt power.

#2 Most of the gains from a UD pulley usually come from driving the water pump slower. In the case of the LSJ, the water pump is not driven off that belt, so a smaller pulley won't help you there. All it'll do is drive the alternator and AC compressor slower. Alternator won't really give you much gain. Driving the AC compressor slower will help out a touch (only when the AC is on). But either way, it won't make up for what you'll lose in driving the SC slower.

 

not a smaller diameter a lighter pulley instead???

 

You don't want smaller diameter on a supercharged vehicle. Smaller diameter will hurt your performance whether it's lighter or not.

If it were the SAME diameter so as not to underdrive the supercharger, but a couple pounds lighter, then it couldn't hurt. But I really doubt it'd be worth your time to bother with it.
