New Turbo System
The original turbocharger for this car was an "E-flow" Rajay unit. It served well but an unfortunate demise killed it. A piece of foreign material entered the compressor and broke the impeller.
I had spent virtually no money on the orginal system and at the time that was one of the unique aspects of it. I wanted to build a more potent setup and utilize more technology that I couldn't use at the time I built the original setup.
The links on this page detail different aspects of the buildup, and explain the components used. Click the highlited heading of each section below for details of that area.
