Quantità

Bigger displacement, more TORQUE and more POWER.

Our 5150 Autosport Bully Stroker kit is specifically designed for BMW S58 Engines.

Utilizing CP-Carrillo Pro-Xtreme Forged Pistons and Pro-Xtreme Rods, as well as the 5150 4340 Billet Steel Crankshaft, our stroker kits have stood up to the tests and trials of high horsepower applications time and time again.

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

5150 stroker kit offers displacements ranging from 3325 cc to 3404 cc, depending on the selected bore size:

84 mm bore size results in a displacement of 3325 cc
85 mm bore size yields a displacement of 3404 cc

The engine block needs to be clearanced. A professional engine builder is required.

A special thank you to our partners at RK Autowerks, who were an integral part of this project and worked tirelessly with our engineers to create this kit, as well as being the first to test this kit in their world-record G80 M3. Without them, this truly unique, ultra-high quality kit would not be possible.
