This is 150 dollars for oil and spark plugs and coolant. That and your 44 dollar thingey leaves 800 dollars for a turbo charger, fuel system, ignition system ,engine work ,inter cooler, fabrication of pipes and flanges.wiring ,solder ,shrink tubing, tape,electrical connectors, nuts, bolts, washers ,paint and a whole lot more.
