Honda EG K-Swap ProStreet EFR T3 IWG Turbo Manifold

Honda EG K-Swap ProStreet EFR T3 IWG Turbo Manifold

Full-Race’s K-series Single Scroll EFR Internal-WG turbo manifold evolved as an option for those looking to have fast spooling, reliable HP without the complexity and weight of dual external wastegates, BOV, and boost controllers. Ideal for road racing and street/strip setups, this proven design will spool faster, last longer, and produce more reliable power across the entire RPM range than any other manifold on the market. EFR internal wastegate requires ‘C-housing’ 0.92 A/R EFR turbochargers and maximizes firewall and brake master cylinder clearance.

Single Scroll systems separate exhaust pulses, allowing for faster spool while eliminating high pressure reversion. We designed the K-series Single Scroll to take full advantage of this and spool medium to large turbos faster than any other design on the market – carrying torque throughout the entire powerband. This produces an exhilarating experience for a built street/road race car or a high-boost drag race application.

T3 EFR Turbo Options: EFR 7064, EFR 7670, EFR 8374, EFR 9174, EFR 9180 with 0.83 A/R Undivided IWG
