Available with the holes machined into longer slots to compensate for extra slack when using a 5SFE oil pump with a smaller pulley. This is how we do it at KO Racing on all of our engine builds. The holes are slotted to allow an additional 4-5mm of travel when setting timing belt tension.

Select the KO Modded option if you don't want to skip any teeth on a built engine with larger lift camshafts and oversize valves (read: interference motor).
