There was also a Japanese domestic market only Civic Type-R, that was only available as a hatchback and 5-speed manual with LSD. This model was equipped with a powerful B16B (185 PS (136 kW) at 8,200 rpm) (AKA PCT), which is essentially a destroked version of the Integra Type-R B18C engine. The chassis was given the designation EK9. The EK9 was very special as it was essentially based on the JDM EK4 SiR but taken out of the production line and given additional reinforcement to the chassis and body shell. Weight was also meticulously removed to create a light weight racecar feel.
Other additions over the EK4 were bigger brakes, quicker steering ratio, specially tuned suspension, Recaro seats, Momo steering wheel, titanium shift knob, front lip spoiler, rear wing, smoked headlights and a hand built engine that embodied the racing spirit of Honda. This engine featured a hand polished cylinder head, lighter flywheel, redesigned cam profiles, high compression pistons and balanced crankshaft. The gearbox was fitted with a helical type limited slip differential.
