BMW S14 2.7L Stroker Kit by 5150 AutoSport

Bigger displacement, more torque and more power. Our 5150 Autosport 2.7L Stroker kit is specifically designed for BMW S14 engines.

Utilizing CP-Carrillo Forged Pistons and Carrillo or SP Components Forged Connecting Rods, as well as the 5150 Billet Steel Crankshaft, this kit has stood up to the tests and trials of high horsepower application time and time again. We only sell you the products that we have used and tested ourselves.

Other teams have applied this kit in Hill Climb, Road Racing, Endurance Racing, Rally, Time Attack, Drag Racing, Roll Racing, Drifting, and Street applications, all with powerful results.

Benefits of Stroking an Engine

- With higher displacement, your engine will produce greater power and torque, thanks to increased cylinder volume and improved air-fuel mixture combustion
- The longer stroke in the crankshaft increases the leverage on the connecting rods, resulting in increased torque output at lower RPMs
- Improved throttle response
- Increased horsepower
