THE HKS

At the heart of DimensionY is the K20C, paired with an HKS SPECIAL FULL TURBINE KIT using a GT5565_BB prototype turbocharger and dedicated adapter. Cold Air Intake THE HKS spec, LEGAMAX Sports centre pipe, HKS metal catalytic converter and Super SQV IV form a breathing system designed for strong mid‑range and a smooth climb to roughly 450 ps, while SUPER FIRE RACING MR45HLZ plugs ensure stable combustion under sustained load.

Engine management is handled by Mastery ECU Phase3, supported by Power Editor R, an additional injector driver, AF Knock Amp 3 and EVC7‑MR boost control. A fuel‑pump upgrade, HKS regulator, OEM injectors plus an additional 750 cc kit, and a surge tank with a 295 L/h pump provide the headroom required for repeated hard lapping.

Cooling is secured by an HKS R‑TYPE intercooler, S‑Type oil cooler and the factory radiator with sub‑radiator, keeping intake and oil temperatures in check during long sessions. Power reaches the road through an ATS carbon twin clutch, the stock close‑ratio six‑speed and an ATS 1.5‑way carbon LSD, allowing clean, predictable traction out of slow and medium‑speed corners.

Chassis tuning centres on HIPERMAX R dampers in THE HKS specification and a carbon brace, working with ADVAN Neova AD09 265/35R18 tyres on 18×10J ADVAN Racing GT BEYOND wheels to sharpen turn‑in and stability. Braking is delivered by ENDLESS Racing MONO6 TA front calipers with ENDLESS rotors and pads, paired with the OE rear setup. BODY KIT TYPE‑S with HKS front diffuser and TYPE‑S rear wing refines aero balance without compromising everyday usability. Inside, BRIDE ZETA IV 2025 fixed seats, HKS harnesses, a NARDI Sports 34DEEP wheel and bespoke HKS interior details create a cockpit ready for both commute and time attack. This is the Civic Type R brought to its optimum HKS balance—DimensionY.
