i know that v8s are so different from a 4g63 but what i see alot is a billet aluminum under drive crank pulley on the v8s, so i want to know why cant you put the same ones on the 4g63 ( OBX BILLET CRANK PULLEY ECLIPSE TALON GST GSX 4G63 SILV : eBay Motors (item 390185127369 end time Apr-26-10 12:50:20 PDT) ) because if the stock one doesn't have fluid, why wouldn't the ebay one be the same as the stock ones???

 

i dont see any real reason you couldnt.
but im sure someone is gonna tell us

 

The stock one is a dampener, it has a rubber ring inside to dampen vibrations. I would stay away from the ebay one.

 

DSMs technically do not run a full harmonic balancer - it is a vibration damper really, the rubber ring provides insulation to accessories as vibrations transmit easily though tensioned belts. For example excessive crank vibrations could accelerate the wear on water pump, steering, and A/C bearings. However both turbo and non-turbo DSMs have ran billet aluminum crank pulleys for years without issues. Even after tear down there is no visible accelerated wear to main bearings due to lack of OEM damper.

Either way, it is your decision. In my experience, I ran a billet AL crank pulley on my stock motor for 100,000 miles with no issues.

 

Don't do it unless you want to possibly destroy your engine...
