im using a b16 unorthodox racing pulley. so i tried a gsr & b16a2 alternator belts but they dont work?!?!? the gsr one is way to long and the b16a2 is just short by maybe a inch but i already adjusted the alternator to the farthest it can go. Got any idea what alternator belt i gotta use...im using a stock gsr alternator w/ b20 alternator backets. thanks in advance

 

Go get a piece of string and wrap it around all the accessories in the middle of the adjusting range. Then measure it and go to the parts store and tell them how long of a belt you need.
Or tell the guy at your local part store that you want a belt an inch longer and play the guessing game.

Quite simple.

 

i didnt know they did that thanks
