After years of record-setting success with our N55 and S55 Lift Kit camshaft upgrades, Dorch Engineering is proud to introduce the B58 Lift Kit — a ground breaking fuelling upgrade for Gen1 B58 engines. This innovative kit features a billet OEM-spec exhaust camshaft, custom-engineered with a high-lift fuel lobe that delivers an additional 40% fuel flow capacity when paired with your Dorch HPFP, dramatically increasing the fuelling limits of the direct injection system.
The B58 Lift Kit exhaust camshaft retains the OEM cam profile, meaning there’s no need for upgraded valve springs and no complex tuning adjustments required. Installation is straightforward, and the camshaft works seamlessly with the factory valvetrain and DME, preserving OEM-like drivability while unlocking the fuelling capacity needed to support big turbos, ethanol blends, and high-boost setups.
With the Dorch Engineering B58 Lift Kit and Exhaust Camshaft upgrade, Gen1 B58 owners can achieve higher power levels without compromising reliability. Designed for BMW 340i, 440i, 540i, 740i, and other Gen1 B58-powered models, this kit ensures your fuel system keeps up with your performance goals, making it a must-have for serious B58 enthusiasts.
Combining OEM fitment, cutting-edge fuelling technology, and proven performance gains, the Dorch Engineering B58 Lift Kit and Exhaust Camshaft upgrade offer the ultimate fuelling solution for B58-powered builds — whether you’re aiming for record-breaking horsepower or future-proofing your high-performance street car.
*Billet machined camshafts are not to be confused with compromised regrinds of the stock camshaft.

ADDITIONAL INFORMATION:
| Brand |
|---|
PREPREG is a common term for a reinforcing fabric such carbon which has been pre-impregnated with a resin system. This resin system (typically epoxy) already includes the proper curing agent. As a result, the prepreg is ready to be laid into the mold without the addition of any more resin. In order for the laminate to cure, an autoclave production process is used, a combination of high pressure and heat.
- Maximum strength and performance characterictics. In a hand layup production process, it is difficult to achieve 50% fabric and 50% resin content. Typical hand laminates, even when vacuum bagged, end up with a significant amount of excess resin. Excess resin increases brittleness and reduces overall strength properties. On the other hand, most prepregs contain around 35% resin. This is ideal for maximum cured properties and generally impossible to achieve in normal hand lamination.
- Uniformity and repeatability. The prepreg is of uniform thickness and each part coming out of the mold may theoretically be the same. Vacuum bagging technology may have some errors in processing, but prepreg ensures production consistency.
- Reduce curing time. After the thermal curing cycle, no need to wait for the standard 48 hours can be fully cured.
- Aesthetics. Although prepreg processing still requires mold preparation and demoulding, prepreg processing eliminates air bubbles, makes it easier to obtain a smooth, glossy surface as well as eliminates any seaming lines.
