I have the 10% Underdrive Pulley in Grey in my for sale thread mick. Let me know if your interested. But back on topic,i've used it in my car for at least 30,000-35,000km and never had a problem with it but obviously the 1NZ-FE/2NZ-FE version. Lots of Yarisworld people use it, so im sure the 2ZR-FE would be just as good. But there was a debate about the harmonic dampener etc on main thread on the other forum i think. But most people thought it was fine. I think.
