Umm.. I really think that would entail ALOT of work.. and cost would be similar of buying the 2JZ cam gears and having those machined to fit... tho thats only a guess... I could be very wrong.
They don't fit directly. You need to bore out the ID another mm to fit. I had to do this on my HKS cam gears. You could even machine the 7M gears to fit. You also need to convert the early 5Ms to the later round tooth belt to use the cam gears. Stupid thing on Toyotas part is that the 5M/6M, 7M, & 1JZ/2JZ cam pulleys all have the same outer belt pulley part. Just each one has a different bore diameter. Kinda stupid on their part to redesign it for each engine.karaki said:The 7m cam gears won't fit the 5/6m...but the 2j ones will. Plenty of selection for those:

Exactly what i was thinking Dave!Dave A. said:What about drilling out the dowel pin hole in the stock cam sprockets and inserting a eccentric bushing to advance or retard the cams.8)
