theres 2 diff types, one is just smaller pulleys which ='s in ******* up ur car, then the other type are same OEM size just made from a lighter material so ='s in more rotations also not damaging the car. and the aems n onorthodox are both the lighter weight pulleys

It's not the size that you should be worried about, Ail45. It's the fact that if you replace the Crankshaft pulley, you're eliminating your Harmonic Balancer, which will produce increased wear and tear. And, you won't see more than 3whp, guaranteed.

Bingo, a LOT of damage has been done to many a honda engine by replacing the OEM crankshaft pulley with an after markey one. harmonic balancer is there for a reason.

whats going on here? there are only 3 replaceable pulleys as far as my knowledge. aem makes tru-power underdrive pulleys which replace the power steering and alternator pulleys. they are lighter and larger on the power steering pump and smaller on the alternator to help reduce drag. you see 1-3 hp increase with these in the HIGH rpm range. however, the only damage you'll see from these are usually due from straining the alternator.
unorthodox makes crank pulleys which are the same size as stock, just made out of CNC aluminum which makes them a lot lighter than stock and doesnt have the harmonic balancer. THIS IS THE PULLEY THAT WILL MAKE YOUR MOTOR TEAR ITSELF APART FROM THE INSIDE OUT. but it will usually yield a good 15-25 hp. if you like rebuilding motors regularly, this is the mod for you.

Re: (skipbarber)
Guys, let's not go overboard with the pulley urban legends. On a motor that has a true harmonic balancer, like older domestics...a different crank pulley will screw up the motor.
But on a Honda motor, I have YET to see a good quality pulley do any damage at all. I've been running the full unorthodox setup on my ITR since 2000, and there is nothing wrong with my motor. Same thing goes for my RSX, my EF Si and same thing for my old GSR. A ton of people I race with also use them on their Hondas and none of us have seen any damage that was directly related to a crank pulley.
Most of the pulley myths happened because people were installing inferior quality non-balanced crank pulleys on their cars (generic unorthodox copies). The good quality ones are all milled to standards.
If you want to be safe, then buy the AEM setup that just replaces the pump pulleys. But these don't account for much HP. The crank pulley is where its at.
Also, someone name me a Honda motor that is not internally balanced...

exactly thats what im sayin because i know A LOT of people that have pulleys b4 on their car n ect n nothing ever happened to them only thing i could say people blew thier engines cuz they didnt know how to drive or for one of my friends cases, he ran too much boost on his vw vr6 gli
