The team over at 4 Piston in Danville, Indiana make some serious powerful Honda engines. Take for example their 2.7 L K-Series inline-four built specifically for FWD drag racing. They reach 2.7 L by increasing stroke to 106 mm and bore to 90 mm. Inside you find a Winberg crankshaft, Wiseco pistons, GRP aluminum rods, and a 4 Piston CNC head capable of flowing 430 cfm. Once together you have an inline-four that is capable of producing 500 horsepower naturally aspirated and 10,000+ rpm (shifts at 10,600 rpm).
