NST recommends using the same belt when making both modifications, however, the marks on the auto-tensioner no longer line up where they are supposed to (page EM-13 in the SM) - about 1/2 inch off. Will this be a problem and does anyone know the number of a belt that is slightly smaller? Thanks.
Wow, you got yours installed quickly! Glad to hear that you have noticed a difference in your throttle response and acceleration. This is definitely a mod that helps in that department.

It is true that the auto tensioner will not sit in the same location as before, but this is not going to be a problem. Our local test car has been running these pulleys for about six months now, on the OEM belt, with no issues.

Thanks again for the quick post and the positive feedback. Good luck and have fun with all your future projects!
