I've seen pictures and read about these systems but never had one in my hands. I probably have pictures of early systems from 95-98 era saved on my desktop machine. I'll bet Dale Ulan has plenty of experience with them. As far as that Vortec engine, for a long time GM was selling 1.8 and 2.0 liter industrial engines that were descendants of European engines and surprisingly enough, they were the same engine family used in the Pontiac turbo Sunbird. I think they've stopped that now but I'm still curious. Any chance you snapped a picture?
