Product Description

The Turbosmart TS-0203-1026 Kompact Dual Port Blow-Off Valve is a direct OEM replacement for the plastic factory BOV on the RB-series Nissan Skyline R32 GTS-T, R33 GTS-T, R34 GT-T, and the Stagea WC34 -- covering the RB20DET, RB25DET, and RB25DET NEO turbo I6 engines. The factory plastic blow-off valves on these cars frequently crack with age, causing significant boost leaks that prevent the turbo from reaching full potential. The Kompact Dual Port replaces the OEM unit with machined billet aluminum construction that holds boost without leaking under any condition.

The Dual Port design vents 50% to the atmosphere and 50% back into the air intake. Sequential port timing keeps the valve quiet during low-boost cruising, then delivers the signature vent-to-atmosphere whoosh at peak boost -- ideal for owners of stock to lightly-modified RB cars who want classic BOV sound in a space-efficient OEM-replacement package. Direct bolt-on installation using the factory mounting location. Hand-assembled and quality tested in Australia, backed by Turbosmart's 1-year limited warranty.
