I've been looking to swap the very heavy front pulley/damper on my 200SX with VG30 engine for a light weight aluminum piece. I'm assuming I'd have to make my own since I've never seen commercial version, but that's ok.

However, when I see the stock piece - heavy and with a rubber ring included, I worry that the VG30 has a major torsional vibration problem. So my question - does anyone know whether the stock-style damper is necessary for engine reliability? I'd like to lose the weight and slow the water pump, but not at the cost of shortening the engine life. Anyone have experience with alternate pulleys on this engine?

Thanks
