dude, need ur advice. so i'm looking to adding UDP to the zetec and i can't seem to figure out which direction to go. such as, should i go with the steeda (crank and water pump pulley) set up, or the FSWerks (crank only) pulley, ooooor the CFM (crank and water pump pulley)? i haven't put the headers on yet for I'm in the process of getting a new alternator, water pump, oil pump, belt, etc. Kinda like a bigger tuneup from just your basic oil change. Want new parts before winter hits and before I start on major power gains. Also, the belts, the gator serp belt is cheaper then the regular ford belt. Advice or preference?
