I dont think so... part of what they do is change the cam to increase effective compression (i assume) and the exhaust is a major part of it too i think. Also keep in mind a "hot"cam is bad for turbo charged cars. the best charistics for a turbo cam is similar to a economy cam. very little overlap (if any) and higher lift. I'd go with just a TT setup. I am also working on a custom ground turbo cam set. Darkstar -----Original Message----- From: Scott Gardner [mailto:gardners14@xxxx] Subject: [DML] Stage One 197hp kit and twin turbo? Does anyone know if the 197 horsepower "Stage One" kit from DMC in Texas would be compatible with the twin turbo kit from Turbo Manifold Company?
