Problems

Did not even waste my time to install

Tips

DO NOT, I REPEAT do not install this pulley

Thoughts

I have no doubts about a proven increase in performance, but at what cost? It's not worth the LONG TERM damage you will do to your engine especially the KA24DE and the KA24E family.

O.K. I know your reading this and want an explanation so here it is. I was gonna install this on my '95 but I checked with the guys a AEM and Jim Wolf Technology. They both strongly discouraged me against it.

--On the Original Crank pulley the Harmonic Balancer (VERY IMPORTANT) is built into the pulley. On the one from Unorthodox they don't even retain use of the harmonic balancer. You see Nissan is not stupid, that wouldn't have put a harmonic balancer on the car if it wasn't needed. And believe me ya'll that truck motor that we have under or hood does need a balancer because it has such a long stroke and high compression. But mostly because of the stroke. You risk Warping the crank, a lot of vibration on the crank back and forth, which will cause the rear main seal to leak, front seal to leak, which does damage to the relability of our cars. ---Save your money and reduce rotational mass on the other end of the engine. invest in an aluminum flywheel. Doing the flywheel will give you better throttle response and acceleration.

Hope that this bit of Info has helped.

Remeber not all Underdrive pulleys are bad, but this particular one is for Our cars
