Thanks Guys I ordered a new stock pulley from Mazda Comp today and a racing beat aluminum just to be sure since I think we have a timing problem. I want then in hand when we hit the dyno.I found out about the pulley mis match possibility the hard way. I tried everything to get the timing right. I was convinced the crank angle sensor was not going in right. I got the mis matched pulley on a rebuilt engine. A friend had the racing beat one piece pulley that we used to find another pulley that would work.

Hmmm Stock Pulley arrived and I can't see any marks in the edge of the pulley??Without removing the hub (to see the keyway) there is really no way of telling if the marks are right compared to a "good" pulley. Do this in the shop before you head to the dyno. No sense in wasting dyno time.
