SpeedFactory Racing Engine & Billet Performance Components

Performance Engine Components for Honda B-Series, D-Series & K-Series Builds

SpeedFactory Racing offers specialized engine components and billet performance parts for Honda and Acura enthusiasts, professional engine builders, and competitive racers.

Our product selection includes high-strength head studs, performance head gaskets, connecting rods, piston kits, billet aluminum components, timing system upgrades, and valvetrain hardware.

These components support a variety of engine-building applications, from naturally aspirated street and track builds to high-boost turbocharged racing engines.

Head Studs & Performance Head Gaskets

Cylinder head sealing is an important consideration when building a high-performance Honda engine, particularly for applications involving increased cylinder pressure.

SpeedFactory Racing offers specialized head fastening and gasket solutions, including 4140 steel head stud kits, L19 head studs for supported applications, and B-Series VTEC fire-ring and copper head gasket kits.

Selecting compatible components requires consideration of the engine platform, cylinder head and block configuration, surface preparation, and intended operating conditions.

Connecting Rods, Pistons & Engine Internals

SpeedFactory Racing offers performance connecting rods and piston products for selected Honda engine applications, including components for D-Series and B-Series builds.

These products support different engine configurations, from naturally aspirated performance combinations to turbocharged applications.

When choosing engine internals, consider compression ratio, bore size, connecting rod length, piston compatibility, engine clearances, and the intended operating environment.

Always verify individual product specifications before purchasing or installing components.

Billet Engine Components & Specialty Hardware

Billet aluminum engine components can provide application-specific features, precision-machined construction, and improved serviceability or packaging, depending on their design.

SpeedFactory Racing's engine and billet product lineup includes specialty fittings, billet engine hardware, engine accessories, and selected valve cover components.

Our billet products are designed for specific applications, so customers should review product descriptions for compatibility, dimensions, and installation requirements.

Timing System & Valvetrain Upgrades

SpeedFactory Racing offers timing system and valvetrain components for supported Honda engine platforms, including heavy-duty timing belt tensioner springs and upgraded valve spring and titanium retainer combinations.

These components may be relevant when modifying camshafts, engine speed, or other aspects of a performance engine build.

Proper component selection and installation are essential for maintaining reliable valvetrain operation and engine timing.

Choosing Components for Your Honda Performance Engine

Building a high-performance Honda or Acura engine requires matching components to the engine platform, intended power output, fuel type, compression ratio, operating RPM, and vehicle application.

For example, the component requirements of a naturally aspirated B-Series street engine may differ significantly from those of a dedicated turbocharged drag racing engine.

Browse the SpeedFactory Racing Engine and Billet Parts collection to explore available products and review technical specifications, fitment information, and installation requirements.
