Sorry Frank,
   Gotsta dissagree.  But I do like the addtiional instrumentation.  oil
Temp, pressure, boost, A/F ratio, stuff like that is good to monitor, but
you don't need a big gauge with a needle like a tach or speedo.  I wiil
probably use this in my subie conversions.
    But I will retain the stock speedo and tach.  I like the vanagons
instument cluster.  For experimental or not quite perfected stuff, some
additional monitoring is nice.  Once that is perfected, I prefer idiot
lights.
     I think a totally perfected engine conversion would have stock idiot
lights and be totally stealthy.
