HKS SUPER SQV 4 GT-R BNR34/BCNR33 RB26DETT 1995-2002 Skyline GT-R
The HKS Super SQV4 GT-R sequential blow-off valve replaces both stock primary and secondary valves on twin-turbo RB26DETT engines in Nissan Skyline GT-R models. This dual-valve design manages high boost during hard driving for immediate pressure release and sharper throttle response. It safeguards turbos against compressor surge while matching the GT-R sequential turbo system.
Key Features
- Dual Valve Construction: Primary valve opens at low boost secondary valve at high boost to sync with GT-R sequential turbos for accurate pressure control
- Titanium Nitride Diaphragm: 50% thinner and lighter than standard to resist fatigue corrosion and extreme heat pressure
- Progressive Spring System: Four included springs adjust boost from 5 to 35 psi for street or track setups
- Swivel-Type Adapter: Matches GT-R intercooler piping flanges with 360-degree rotation for simple hose routing and tight seals
- Hard Anodized Aluminum Body: CNC machined for durability and resistance to wear through 100000km of use
Product Notes
- Direct bolt-on replacement no cutting or modification needed to stock GT-R piping
- Requires stock solenoid valve operation for full sequential function
- Secure in original HKS box for protection during transit
Installation Notes
- Professional installation recommended.
- Bolts directly to OEM blow-off valve mounting points on intercooler pipes
- Includes gaskets O-rings and hardware for GT-R specific flanges
