We have a ion with a stock pulley I have a 2.8 pulley i want to put on can i just put the pulley on the car and get a new belt prob going to have to add fuel dont know. Anyone know anything about these things i have no clue

ok, for the 2.8 you should REALLY look into dual pass and a Front mount..... you will also need to upgrade to 60# injectors and get a custom tune for the entire thing. You can only get the stage 2 belt for smaller belts, so get that. I think they are like 50 bucks though
