Under the hood, a B20B four-cylinder from a Japanese market SMX micro-van is nestled in the engine bay. The B20 retains its stock 84mm x 90mm bore and stroke, but has been fitted with a VTEC head from a Type R Integra. This swap, known as a Frankenstein engine, gives the engine the advantages of variable cam timing at the top-end and the advantages of additional displacement in the form of torque on the bottom-end. V-Spec handled the engine swap and shocked the Frankenstein motor to life. The head was fitted with Top Fuel turbo-spec cams, but was otherwise left stock prior to being secured via ARP hardware. The intake tract is a Type R affair from the throttle body to the manifold. A set of 534cc Blitz injectors, a Top Fuel high-flow inline pump and an AEM regulator and rail make up the fuel system.
