Today we'll be installing the 034 Motorsport High Pressure Fuel Pump Piston Upgrade Kit for the 2.9L and 3.0L EA839 engines. I'm going to be installing it in my 2018 B9 S4 as part of my Stage 3 build to support a larger hybrid turbo from The Turbo Engineers. You'll definitely want to stay tuned for the rest of this video series!
This solution from 034 is a drop-in replacement for the factory HPFP piston. It delivers 37% more fuel flow over the factory pump design. This allows for added fueling for e85, race gas, and pump gas. The system will support hybrid turbos and 034's range of + (Plus) tunes that take advantage of the extra fueling to make a bit more power on stock turbos.
