TURBOSMART FPR KOMPACT FUEL PRESSURE REGULATOR – BOSCH/BARRA (SLEEPER)

The factory in-rail regulator is a common bottleneck on mildly modified turbo cars. The Turbosmart FPR Kompact (TS-0404-1005) is an all-black, billet fuel pressure regulator built to replace it, offering adjustable, class-leading fuel control in a small footprint for builds up to around 800HP.

A CLEAN UPGRADE FOR OE AND MILD BUILDS

Where the stock regulator is a fixed, non-adjustable unit, the FPR Kompact is a direct bolt-on replacement for the factory Bosch in-rail-style regulator fitted to VAG (Volkswagen Audi Group) vehicles and the Ford 'Barra' inline six found in the Australian-delivered Ford XR6 Turbo. It's the simplest way to gain accurate, adjustable fuel pressure control without a full aftermarket fuel rail conversion.

PRECISION WHERE IT COUNTS

Inside, a stainless steel valve seat and Mil-Spec diaphragm deliver a true 1:1 pressure ratio and fast response, so your fuel pressure tracks boost accurately from idle to full throttle. It's compatible with all fuel types, including E85.

Key Features:

  • Adjustable 35–80psi Range – Suits OE-level and mild bolt-on upgrades to 800 HP
  • Stainless Steel Valve Seat – Suitable for all fuel types, including E85
  • True 1:1 Ratio & Response – Class-leading accuracy and boost tracking
  • Milspec Diaphragm – Built for consistent, reliable long-term performance
  • 1/8 NPT Gauge / Sensor Port – Mount a mechanical gauge or pressure sensor
  • Unique Locking Collar Design – Secure, tamper-resistant pressure adjustment
  • All-Black Billet Finish – Suits Turbosmart's current FPR aesthetic
