what belt am i supose to use on an h2b set up?....i have an alternator pulley with 4 teeth and a crank pulley with 5 teeth..

 

I think you prolly have the JDM h22 pulley.. I think there are 4 teeth but its a five rip pulley.. If you have the stock alternator bracket.. I think you should be okay with a 38 inch 5 rib pulley... or if im wrong about the teeth get a 4 rib 38 inch...

 

I took some zip-ties and made a belt to size I needed and went to the auto store. Then I matched up my homemade belt to real belts and found the best size. Worked fine, yee.
