Have been posting a lot about parts. In process of doing a b20 vtec swap in my 88 crx si and bought someone else's incomplete swap with huge box of parts. This is suppose to be able to be used on a B series but not sure and couldn't find any info on it or part #. It has 4 grooves so I'm thinking it may work but since the b20 vtec is frankensteind enough already wondering if it would cause a problem. Any help would be appreciated.

No. That looks like a one piece design with no mass to it and no vibration damping.

It also has no good way to hold it when you try to remove it in the future.

What are your plans with the car?

 

A lot of c.pullies are one piece designs and would assume (yeah I know) that it's balanced also what do mean "no place to hold it/remove it in the future?" it fits on my stock b20 crank and there's plenty of clearance with the main belt pulley for the cam pulleys. Been trying to find a website for it and came across this:https://honda-tech.com/forums/all-motor-naturally-aspirated-44/anyone-here-running-srd-crank-pulley-879895/

Sounds like a decent piece. Anyone run one?

 

Yes, a lot of pulleys are one piece. And all of them offer no vibrational damping for your motor. The factory one is heavy and designed the way it is for a reason. Without getting into a whole discussion about absorbing frequencies and whatnot, know that that mass is a good thing. It doesn't matter how balanced your motor is, it will always be exposed to a ton of vibration.

The absolute best option is a fluidampr or ati damper, but if you're just street driving the car a factory three ring pulley is a great and affordable option.

As far as the issue with getting the pulley off, that one only leaves you with the option of using an impact gun to get the bolt out. The Honda holder is a great tool and never fails. Also those aluminum pulleys tend to be a real pain to get off of the cranks nose after they have been on there for a couple of years.
