Manley Performance Forged Engine Internals at JXL Performance

When building a forced induction engine capable of handling massive boost, relying on factory cast internals is a guaranteed path to catastrophic engine failure. Founded in the USA, Manley Performance has decades of motorsport heritage, supplying championship winning engine components for everything from high horsepower drag cars to dedicated circuit weapons. By upgrading your rotating assembly and cylinder head with Manley forged pistons, connecting rods, and uprated valve springs, you provide your engine block with the ultimate mechanical foundation required to safely deploy extreme horsepower.

Forged Pistons, 4340 Connecting Rods and Valve Springs

Standard mass production engine internals are highly brittle and simply cannot withstand aggressive ignition timing and huge cylinder pressures. Manley solves this by machining their connecting rods from premium aerospace grade 4340 forged steel. Whether utilizing their incredibly strong H beam design for fast road builds or their legendary Turbo Tuff I beam rods for extreme drag racing, Manley rods ensure your rotating assembly remains entirely bulletproof.

To complement their rods, Manley forged pistons are crafted from high tensile 2618 aluminum alloy, perfectly engineered to handle immense thermal stress while running tight piston to wall clearances. Furthermore, pushing big turbo setups to a higher redline easily overpowers factory cylinder heads. Manley uprated valve springs and titanium retainers completely eliminate valve float, ensuring precise valve seat control and preventing piston to valve contact at absolute maximum RPM.

Targeted Strength for Audi, BMW, Ford and Toyota

While we carry a highly curated and specific range of Manley hardware, it covers some of the most capable modern tuning platforms on the road. For the fast Ford market, dropping Manley forged rods and pistons into the EcoBoost platform is a mandatory step for big turbo conversions.

In the European and JDM scenes, Manley internals provide critical strength for Audi and VW platforms running the high output 2.0 TSI EA888.3 engine, such as the Audi S3 and Golf R. For BMW enthusiasts, Manley supplies the heavy duty hardware required to push the N55 engine in the M135i well beyond the 700 horsepower mark, alongside vital strength upgrades for the FA20 engine found in the rear wheel drive Toyota GT86.

JXL Performance supplies genuine Manley Performance components to engine builders worldwide. Please check individual product listings for accurate availability, as lead times can vary significantly for custom compression ratios, specific rod lengths, or special order engine sets.
