Actually, it isn't truly a "factory" turbo. DMC had farmed this out to a sub-contractor: Legend Industries. There were supposed to have been two prototypes with twin turbos and intercooled. Nice setup. DMC just sent them a couple of the first cars off the line to work with. So the factory never did anything with the turbos. It was all done at Legend. I heard once that Legend went under when DMC went bankrupt. Supposedly too much invested in the project and they never got paid by DMC. This part is just hearsay, so if anyone knows differently I'll be glad to find out. :) There is a picture of the Legend setup in Stainless Steel Illusion. I'll scan it and post it on the Mid-State DeLorean Club site today. Look in the Gallery section.
