René Köchli has competed in Swiss hillclimbing for several years in his Honda Civic EG6 hatchback. The car has seen three iterations and several engine swaps. The current engine is a 2.7 L K24 inline-four built by Veicomer in Loures, Portugal. The engine features a Darton sleeved block, 4Piston stroker kit, billet 106 mm crank, 4Piston rods, and Wiseco pistons. It made 390 horsepower thanks to a tune by Marco Zoa and his company R-Performance Switzerland. Power is sent to the front wheels through a Sadev ST82-14 six-speed sequential transmission.
This video is a recap of Rene’s 2018 season running a 2.4 L K24 inline-four
