Hey guys I am curently doing a B20 Swap into my EF chassis and ran into a clearance issue using innovative mounts. I cleared the alternator pulley just fine but my pulley is rubbing against the firewall. I know it is a heated debate wheter to use the CTR N1 pulley because of harmonics or whatnot, I am going this route however because the B20 pulley is just too big in diameter and extends far because of the 3 belt areas. I was wondering what size serpentine belt should I use to make it line up with the stock alternator on the B20?
