Well, I had posted before about a problem that I'm having with the Unorthodox Crank pulley. Turns out, there might not be anything wrong with the specs of my particular pulley, nor do I think anything is wrong with my crank/crankcase.

I think they sent me the wrong part!!! If anyone can help me, I'm trying to see if the part # that was shipped is compatible. I have a b13 sr20 (obviously). The outside edge of the crank pulley reads P/N 0210107 REV E. On UR's website, nothing matches that exact part number. Also, the part number recommended for my vehicle is P/N 0210007__. Notice the added 1 in the 5th digit of the part number. The "closest" matchup of part numbers belongs to the crank pulley for the ga16 (P/N 0210108) but nothing is really a perfect match.

If someone could please confirm the existence of P/N 0210107 and confirm that it is a viable crank pulley for an sr20, that would be great.

Thanks,
Chad

P.S. The pulley is "wobbling" once mounted to the crank. We've got it torqued down a ton and it still wobbles terribly. The inside diameter of the UR is within a thousanth of the stock pulley and I'm even more confused about where it is wobbling...

If you like your engine, take the pully off yesterday!!! Something like a crank pully that is "wobbling" is bad news!!! When I worked with BMW engines, anything odd like that spelled trouble down the road for an engine so it was replaced. Take it off and sort your part number problems then. I wish I could help you more. Maybe some one at JWT can help.?.?
