I don't know if it's exactly what you're looking for but look at Dakota Digital.
Anyone know if there's someone out there who makes "build-'em-yerself" digital engine gauge kits? What I'm lookin' for are digital engine gauges that look just like a standard Autometer gauge, but with an LCD or LED digital readout instead of the needle.

Cyberdyne and a few other companies makes them too. Any of the hot rod/custom or import car magazines and they are full of adds for these things. Several companies also make all in one/multifunction digital gauges that fit into a single hole space and replace all of the seperate gauges. Lowrance, Seagauge, Nordskog, and it think Livorsi to name a few.
Or check out the EMO series...
