Jarred Willey received his Great-grandmother’s 1966 Mustang when he was 16 and cherished driving it with its 289 ci Windsor V8 for many years. But he also had a passion for Honda vehicles and engines. So, he combined his two loves into one unique creation by adding a Turbo Honda K24 engine to the Mustang last year.

Jarred swapped out the 289 ci V8 engine with a turbocharged 2.4 L K24 inline-four engine, mounted on modified S2000 mounts. The engine boasts a JDM K24A block and head, with modifications including a K20 oil pump, a KPower intake manifold, a 44 mm wastegate, and a GTX3485RS ball bearing turbocharger.


A S2000 radiator and hoses maintain the engine’s temperature, and 2.5-inch piping lowers air temperature through an intercooler. The engine runs on E85 fuel through Bosch 2200 cc E85 injectors, powered by a Deatchwerks DW400 E85 fuel pump. All components are managed by a Hondata KPro V4 ECU.


Jarred paired the K24 engine with a Nissan CD009 six-speed manual transmission using a PMC Motorsport adapter and a 250 mm flywheel. A custom driveshaft transfers power to an 8-inch rear end, fitted with a Yukon limited-slip differential and 4.11 gears.
