Honda Tuning magazine's entry in the RSX Challenge boasts a naturally-aspirated engine built by After Hours Automotive. They started with a fully prepped K20 block from Benson's Machine and installed Darton sleeves and a Castillo-prepared CR-V crankshaft. JE pistons are connected to Cunningham rods. IPS camshafts enhance the i-VTEC operation, and the engine breathes through individual Hayward Performance throttle bodies. Hondata's K-Pro engine management ensures smooth running, while a Centerforce Cluch and OS Giken limited slip differential get power to the ground. Chassis modifications include Progress Group coilovers on all four corners, D3 Automotive Designs double X-brace and Wilwood brakes.The exterior is all business, with Flex-A-Lite rear windows and a Buddy Club body kit. Inside, Momo Cup seats and Crow Enterprise harnesses combine with a JD Performance cage for a racy look.
