D-Series Single Pulley

Anyone know of a Single Pulley for the Crankshaft on the D-Series? I know you can get the Type R pulley for the B, but don't know if its interchangeable. I'm planning on building a 12.5:1 D16Z6 later this year and looking to free up any extra HP I can.

You mean like the Unorthodox Racing pulley? I had one on my d. It was a single pulley with no A/C and weighed about a pound. If you mean something else than never mind...

Yep, thats what I'm talking about. The Civic Type R came with a 1.8lb single pulley on them, much cheaper route if your working on a B-series than getting an Unorthodox pulley for twice as much. I just haven't seen a single pulley for a D series yet, and don't know if the B-series will interchange.

I found some underdrive pulleys on ebay, but they still have a A/C pulley on it too....plus they are ebay POS.

I'm sorry I never got a pic of the pulley. I could've sworn it was without the A/C but I could very well be mistaken. It was put on the crx like 5-6 years ago so even if it is a single it may be out of production. GL

You could take a oem pulley to a machine shop and have them put it on the lathe to cut it down, and then have it balanced to 8,000 rpm
