Hey Guys,

I am in the process of building another 20v 4agte. I am still in the parts gathering and research stage so bare with me if i may ask some silly questions to get my answers. Ive seen alot of light weight pulleys on ebay and ive almost bought them but are they worth the money? will there be a noticeable difference in performance?

only if your revving it out to 10,000rpm. You would be far better of to get the engine balanced.

Be careful on how they lighten the material. If it involves alot of drilling, the pulley can break along the path of where the holes are.
We have experienced this before on a B16 (Civic) engine for the auxiliary belt pulley . Imagine the torque coming from a FI car would be much more.
