Ebay or
www.homemadeturbo.com/forum/ classifieds. Search for Vortech FMU. Honestly, you're better off using something electronic. FMU's are cheap but it's really a "band aid" way of controller your fuel. The boost transition sucks. Get a Hondata, AEM EMS, or GReddy E-manage if you plan on a "race" set-up. FMU's will not give you the tuning that capability of a race set-up. Trust me, I've done it using the FMU set-up with a 12:1 disk. It was horrible compared to my VAFC hack. Goodluck
