My bad guys I didnt red it all the way I was thinking LS VTEC for some reason you HAVE TO USE THE B16 belt Due to shorer Deck heighth if your doing an LS Vtec Follow my previous Directions the belts are the same between all the B18's and B20. You basicly replaced the Pump with a B16 pump as the ITR and B16 Pumps are almost identical actually there alot of similarities bewteen the B16 and the B18C5 and B18C4.
