I have a set(Crank and Alternator Pulley) of Unorthodox Underdrive Pulleys for a 2004 Civic Si. I would assume like most parts that this would also fit a '02, '03, and '05 Si. I purchased them for $220, but would sell them for $150 and include free shipping. Email Rick.McCarty@heritagepackaging.com if you are interested.
