BMW S54 3.0L De-Stroker Kit by 5150 AutoSport

The 5150 AutoSport BMW S54 3.0L Destroker Kit is engineered for racers who need high RPM capability and precise engine response. By reducing the S54’s displacement from 3.2L to 3.0L, this kit optimizes the rod-to-stroke ratio for sustained high RPM applications, allowing the engine to safely rev to 10,000 RPM while maintaining exceptional balance and reliability. Each kit includes our 4340 billet steel crankshaft, forged CP pistons, and SP Components connecting rods (with an optional upgrade to CP-Carrillo rods for the ultimate in strength and precision). The reduced stroke design minimizes piston speed and stress at high RPM, delivering faster revving characteristics and improved throttle response—ideal for race, time attack, and high-performance street applications. Every component is precision matched and balanced to 5150 AutoSport’s strict performance standards, ensuring long-term durability even in extreme operating conditions. Why De-Stroke an Engine? Common for track cars Some class restrictions limit cars to 3.0L displacement More top-end horsepower (at the cost of low-end torque) Increased RPMs Reduced friction Greater longevity at high RPMs Improved Crank-Rod Ratio for high RPM applications: De-Stroked = 1.65 Factory = 1.53:1 Stroker = 1.43 Kit Contents  5150 Autosport 4340 Billet Steel Crankshaft, 84mm Stroke Professionally turned, polished, and coated with anti-wear coating Fully balanced SP Components Connecting Rods (Rated for 1,000HP) Optional Upgrade to Carrillo Pro-Xtreme Connecting Rods (Rated for 2,000HP) CP-Carrillo Pro-Xtreme Forged Pistons (rated for 2,000HP) CP-Carrillo Piston Wrist Pins CP-Carrillo Piston Rings CP-Carrillo Piston Wire Locks Final displacement depends on selected bore size: 87 mm bore size for 2996 cc displacement 87.5 mm bore size for 3030 cc displacement Have more questions?
