SR Crank pulley options? OEM, ATI, etc... - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

Apparently my crank pulley is done, it's got a groove in it that chews up a front main seal about every 3000 miles now, it's time to replace it.

I am considering a brand new OEM Nissan one, at about 200 bucks and also considering an ATI balancer at 450 bucks. My car is about 300whp, with no plans to make more than 365wp, and all I care about it dead solid simplicity and absolute reliability. This is a total street car that gets tracked every month pretty hard.

Anyone using an ATI? What did you notice? Good bad? I am less interested in the ATI because of price, and not running a factory belt size. But if someone has enough info to make up for that, I'm all ears.

Anyone have any info on why to get an OEM instead of an ATI?

Thanks in advance guys!
