Mike Fehler built his 1990 Honda CR-X with a 1.8 L B18 inline-four. The motor features Eagle rods, Wiseco pistons, GSR camshafts, FIC 1000 cc injectors, and Skunk2 radiator. Boost is generated by Precision 5558 Gen2 turbocharger on a Ramhorn exhaust manifold cooled by a Go Auto Works fount mounted intercooler. Power is sent to the front wheels through a Competition Stage 4 clutch and B16 S1 manual transmission with a MFactory differential. Mike sent the car to Mad Scientist Auto for a dyno tune where it made 407 hp (303 kW).
