Jdm Type R Pulley?

[Slimtadder]

Is there any difference between a USDM and a JDM Crank pulley or even better a JDM Type R crank pulley? I really want to stay away from the under-drive pulley's.

Thanks Guys

ctr pulley is designed to just run the alternator belt.

powersteering and ac are eliminated.

i'd stay away from aftermarket pulley's because it will throw off the harmonic balance of your engine. honda designs the motor to be perfectly balanced from the factory which means a lightened pulley will change that balance.

theoretically, the ctr pulley would do the same, as other honda motors are designed to run all three pulley's.

i'd keep it stock and make power elsewhere.
