Water pump pulley
 

I just got a set of lightweight pullies for my 7m engine. It came with the alternator, crankshaft, and power steering pulley. Does anybody know if the sell a lightweight pulley for the water pump in a 7mgte engine?

If your replacing a the crank pulley with a cheap ally one, you run the risk of damaging your engine. The heavy stock pulley is there for a reason, the weight of the pulley absorbs vibration from the crank. Links crankshaft torsional vibration. and resonance. If something rattles/vibrates place a heavy weight on the end of it.

im not worried about that...do you know anybody that sells lightweight water pump pulleys?

Ive heard because our cranks are so long, a lightweight crank pulley can accually break the crank

ok this is about the water pump not the crank

Unorthodox Racing 4th one down in list.

Edit: Just noticed, it listed as for 2.5L 1JZ-GTE

so no1 makes it for the 7m engine?

dont buy crap obx racing crank pulley

Uh-Oh!
 

I already purchased obx =| whats wrong with it?

On the crank pulley it does nothing to dampen/control vibrations. As Bill already mentioned, there's a reason the OEM units are heavy.
