Started up the gray 92 SER today after a long hiatus...it is now naturally aspirated, and everything sounds good. Prepping my red 91 to get towed with any junk parts I have laying around. It was a Looooong week of wrenching dropping a full turbo set up car engine, trans, exhaust, IC, piping, etc....then pulling my NA engine, trans, exhaust, etch and throwing it into the grey chassis. I hate working on my back in the driveway but it was rewarding and it occupied all time I had outside of sleep and work.
