Just wondering, is there any of you using tomei pulley? Is it good? I heard its made in Japan. How does the quality compare to the summit or GTspec pulley?

 

Never heard of it. GTSPec here, it's good, but how good it's never been dynoed in the USDM fit yet, and the vendor RavSpec and also importer/supplier of GTspec does not seem interested in funding the Dyno since they are a retail not garage/performance.

 

I didn't know they did any tuning with Hondas. They make very nice cams for the Nissan SR20 motors.

 

I heard those were known for cracking under stress, around the shaft, due to the soft metal. Other manufacturers have addressed the issue by
placing a steal bearing around the shaft or by using a stronger alloy.
