Honda/Acura K-Series Twin Scroll Turbo Manifold
Full-Race has spent years working with Turbo VTEC engines – one thing weve clearly learned is that these engines love to breathe through properly executed twinscroll turbo setups! We believe the K-series twinscroll to be the ultimate high power turbo manifold for the K-series RSX and EP Civic or K-swapped EG / EK / DC. Twinscroll systems seperate interfering exhaust pulses, allowing for faster spool while eliminating high pressure reversion. We designed the K-series twinscroll to take full advantage of this on all size turbchargers. Whether fitting a 3″ or 4″ inlet street turbo all the way up to a massive 6″ compressor inlet drag turbo – carrying torque throughout the entire powerband, not just ‘peak power’ — translates into a faster car. This broad increase in area-under-the-curve produces an exhilirating experience for a built street/road race car or a high-boost drag race application (same manifold & WG setup, just varying turbo size).
Ideal for demanding applications which require huge power output without sacrificing spool or response, this turbo manifold is engineered to break horsepower and ET records. It represents the state-of-the-art in high power turbocharged K-Series performance.
