Hello, My name is Keith, and I have a 89' hatch. I am currently building a Jdm zc motor, and I am a little confused about underdrive pulley's. My stock crank pulley was damaged in transit, so I thought I might upgrade to a lightweight underdrive pulley. After searching online some say not to use them due to excessive wear on the motor. These vechile is not going to be a everyday driver, and I have removed the A/C. Underdrive pulley's seem to be somewhat expensive. What do you guy's think. Should I try to get a stock pulley, or upgrade to the underdrive pulley?.

Also my other question is if I do replace the stock pulley for the 89 dohc 1.6L zc, does it have to be off a zc, or is there another honda pulley with the same dimensions?. Thanks

 

Underdrive pulleys are not an upgrade by any means, don't put them on your car.

 

Alright that's good advice. So if I'm going to replace the stock zc crank pulley, do I need one off a ZC ?.
