Tomei Stroker Kit EJ25 2.6 CP Pistons - Subaru Models (inc. 2004-2021 STI / 2006-2014 WRX)

The Tomei Stroker Kit for Subaru models (including 2004-2021 STI and 2006-2014 WRX) is engineered to significantly boost your engine's performance. This kit includes a fully forged crankshaft, along with forged stroker rods and pistons, designed to increase both bore and stroke. This enhancement results in greater torque and higher RPM capabilities, providing a substantial improvement in power.

Precision Engineering for Optimal Performance

Engine stroker kits involve modifying the crankshaft, connecting rods, and pistons to achieve increased stroke and, in some cases, bore. The Tomei Stroker Kit is crafted to offer these upgrades with precision, ensuring that your Subaru engine can handle more power and deliver superior performance.

BENEFITS OF A STROKER KIT:

• More torque throughout the entire RPM band
• More low-end torque if employing a larger turbocharger on an otherwise factory displacement engine
• Faster response with a conventional or mid-framed sized turbocharger
• More upper-RPM range and higher-revving due to increased bore and displacement
• Increased piston speed
• Maximizes the efficiency of your valves with increased volumetric efficiency and more surface area at higher RPM
• Improves the overall combustion efficiency and volume
• Allows for less surface area available to reject heat in the combustion area
• Improved combustion burn duration by burning the air/fuel mixture faster improves the efficiency

2.6 LITER STROKER KIT INCLUDES:

• Fully forged CP pistons
• Fully forged connecting rods
• Fully forged crankshaft

NOTES:

• Professional installation required
• Professional machining of your engine block required
• Professional assembly required
