Can you guys tell me what kind of pulleys are installed on the water pump and alternator? My engine did not come with a air pump and these pulleys don't look stock so I'm assuming they're for deleting the air pump the correct way. I'm looking to get the correct belt for the water pump/alternator. Thanks!

 

those would be a set of re-colored Greddy pulleys. Wether or not they are the correct way to delete the air pump can be the start of a nasty debate, but check the banzai racing website, they have a chart on there that has what size belt you would need for most applications.

 

those look like Greddy to me.
