Dump Valve Kompact Dual Port SmartPort – Kit Nissan Skyline GT-R (RB26DETT)

Dump Valve Turbosmart Kompact Dual Port SmartPort – Kit Nissan Skyline GT-R (RB26DETT)

Turbosmart is a leading Australian manufacturer specializing in turbo engine tuning, active since 1997 under the motto "Engineered to Win." A long-standing specialist in dump valves (blow-off valves), the brand designs, machines, and tests its products in-house to guarantee reliability, sealing, and performance.

The Kompact range is Turbosmart's entry point into the world of dump valves (BOVs): it targets stock or lightly modified vehicles used on the road, for power outputs up to around 400 hp. It directly replaces the original plastic valve with a body machined from anodized billet aluminum and a lightweight precision piston, which eliminate compressor surge and the boost leaks typical of aging OEM valves. Available in Dual Port (atmospheric sound + recirculation) or Plumb Back (fully recirculating, quiet, MAF-compatible) versions, with interchangeable springs to adjust opening pressure. It is the best-selling range in its category worldwide: a reliable, robust, and very affordable replacement, while the BOV5 and RacePort ranges target more intensive use (track, high power).

Set of two Turbosmart Kompact Dual Port SmartPort dump valves (BOVs) designed for the Nissan Skyline GT-R R32, R33, and R34 (RB26DETT twin-turbo engine). One valve per turbo. It improves boost response and eliminates compressor surge, preserving the efficiency and longevity of the factory turbos, while delivering the characteristic sound of a high-performance BOV.

SmartPort technology keeps the factory ECU and airflow meter (AFM) fully satisfied, a critical point on these AFM-controlled engines. 50/50 split between venting to atmosphere and recirculation to the intake: discreet operation at low boost, and the sound and performance of an atmospheric vent at high load.

Modular design: simply unscrew the atmospheric vent trumpet and replace it with the supplied blanking plug to convert the valve to full recirculation, with no loss of performance. Body machined from billet aluminum, black anodized finish, perfect sealing (zero leaks).
