The company moved to a new location in Rancho Cordova, CA in the mid 1980s, then to El Dorado Hills, CA. The original Comptech closed its doors in February 2007.

Comptech started Honda North America's race efforts in mid 1980s by preparing the first Honda Race Car in North America (1985 Honda CRX). Starting in 1991, Acura reached an agreement with the Comptech Racing to use the V6 motor of the all-new Acura NSX in Comptech's Camel Lights Spice prototype. Acura would go on to take the Lights championship in its initial year, including a class win at the 24 Hours of Daytona. Acura and Comptech would take the Lights championships again in 1992 and 1993, as well as another Daytona class win in 1992 and a class win at the 12 Hours of Sebring for 1993. Comptech engines performed well in the 24 Hours of Daytona Race in the World Sportscar Class in 1994 and 1995.
