water pump and alt pulleys are more cosmetic.. they are lighter, yes. but not enough to make a difference.. i got the 10% crank pulley and the waterpump/alt pulleys as well. i barely can tell the difference from the oem.. but they look cool!
I am a bit on a budget, would it be worth just getting the "NST 10% Underdrive Crank Pulley 1.5L" only?
