thanks man,

that helped a bunch. but are you sure the h23 and h22 use the same pulleys? i thought that the vtec model pulleys(aftermarket) and si pulleys(aftermarket) were not the same size.

also i looked at the grooves and ribs on the pulleys. the power steering pulley itself has 4 grooves cut into it and the alt pulley has 6. which means that the ps belt will have 3 grooves (4 ribs) and the alot belt will have 5 grooves (6 ribs) ribs being the part that is raised and grooves being...well, grooves inward.

is that what you meant? i get confused sometimes

thanks
