Takes over where the factory regulator stops
GO FAST BITS FX – S 8051 BOSCH REPLACEMENT FUEL PRESSURE REGULATORS FEATURE
* Direct fit replacement for Bosch clip in regulators
* 1/8″ NPT gauge port
* More than double the flow of the factory regulator, allows increased pump capacity without having to replace the factory fuel rail
* Gasoline, ethanol, and methanol compatible
* Double layer/double reinforced diaphragms with a burst strength exceeding 1000psi
* Teflon co-polymer seat with stainless valve to retain fuel pressure longer after shut down
* Spring pre-load adjustment platform is o-ring sealed and does not leak vacuum/boost
* Static pressures adjustable from 1.4-5bar (20-72psi – subject to pump flow and factory return line restriction)
* Completely serviceable
GFB’s popular and compact FX-S Fuel Pressure Regulator is now also available as a direct drop-in replacement for the common Bosch regulators that clip into the fuel rail.
If you increase the performance of your engine, you need to ensure your fuel system can deliver the goods or you’re going to have a bad day! Upgrading the fuel pump is the first step, but doing this alone will usually result in excessive fuel pressure, especially at idle. This is because the factory Bosch regulators typically don’t flow enough to support larger fuel pumps, especially with turbo E85 setups that demand high fuel flow rates.
Rather than replacing the entire fuel rail, or using an adaptor with a separate fuel pressure regulator, simply clipping in the FX-S 8051 will allow you to run a much larger pump setup even with the factory rail. And if you need to adjust the fuel pressure, that’s no problem – unlike the fixed-pressure Bosch regulators, the FX-S can be adjusted from 1.4bar to 5bar.
Like all GFB FX regulators, the FX-S 8051 is compatible with pump gas, Ethanol, or Methanol, and also incorporates a soft Teflon valve seat (rather than metal on metal) that will always positively seal and hold fuel pressure on shut down for reliable engine startups.
The double layer diaphragm has twice the reinforcing material of the single layer type used in most regulators, and as a result the burst strength exceeds 1000psi!
The 1/8” NPT port can be used for a fuel pressure gauge or electronic pressure sensor, or it can simply be plugged using the port plug provided.

What makes GFB blowoff valves different and better?
Our new TMS Turbo Management System don't throw your BOOST away but INCREASES IT BY up to 40%. GFB's Turbo Management System (TMS) parts offer multiple performance benefits over factory diverter valves. We looked at the concept named ‘blowoff valve’ and took this to a whole new level! Basically the main benefits are:
MORE POWER - BETTER RESPONSE - BETTER DRIVE ABILITY - GET THE SOUND OR NOT.
How to choose a BOV
With the vast range of GFB blow-off valves, questions rise 'Which blow-off valve is the best?' and 'Which blow-off valve should I use?'
The first question is easy to answer: There isn't actually a 'best' in terms of quality. All GFB blow-off valves use the same high-quality internal components. So, provided the right BOV is fitted for your particular vehicle, they all offer the same performance benefits of improved throttle response and reduced lag. The real question is: How do you select the valve for you?
The first step to decide on 'your' BOV, is whether or not you want to hear it, and if so, how much? The following chart lists the “noise ratings” of our blow-off valve range. The final decision will then be based on how much control you want over the blow-off volume level.
GFB boost controllers use a more consistent needle-valve bleed system, which brings boost on just as fast as any ball-and-spring system, and generally more quickly than a factory boost control system. On the productpages you can find a comparison of the GFB controller to other major brands, guess who wins this standoff? GFB!
A GFB boost controller will give you the added benefit of not only being able to adjust the peak boost level, but in most cases will bring the boost on earlier, resulting in more power throughout the rev range.
The reduction in rotating inertia (we've removed about 2kg by using 6061 T6 aluminum billet) means that the engine can accelerate much quicker during the times it is making very little power before the turbo spools up. The result is better drive ability off-boost and better acceleration, which is especially useful for those with large turbos that only make power in the upper rev range. The smaller size of the crank pulley under-drives the power robbing accessories so that the upper end of the rev range is less burdened, while still allowing them to operate properly.
Short Shift Kits
The GFB Short Shifter is the same height as the factory shifter, it is the actual distance that the gear stick moves between gears that reduced.
Very simple to install. All of the installation is done from inside the car, without having to jack it up and crawl around underneath. Only a few basic hand tools are required, and the necessary hex keys are supplied.
The maximum throw reduction varies for different models. Early WRXs had a particularly long throw, so the maximum reduction with the GFB kit is around 50%, whilst on later models it is closer to 40%. In either case, it is possible to reduce the distance per gate to about 30mm. Whilst it can go shorter, the shifting force becomes too great for comfort, and some of the shift feel is lost.
