My basic transportation 280 is a 78 280 with a 83 turbo motor with a steel headgasket. It has a t3/t4 with a 62-1 turbo. A modified Grand National intercooler. Home made meth kit. It has a stock 78 trans. 3.70 posi out of a 300z. An ACT street clutch. Stock 84 300 replacement injectors. 79 distributer with a MSD. The car ran a 12.6 @110 last run on MT drag radials. It's fun running quick for low bucks. Turbozick
