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

Engine Power and Displacement Upgrade

The Tomei Stroker Kit for the EJ25 engine is designed to significantly enhance the power and displacement of your Subaru. This kit includes a fully forged crankshaft, stroker rods, and pistons, all meticulously engineered to handle high-performance demands. By increasing both the bore and stroke, this kit improves torque and allows for higher RPMs, leading to greater overall power output.

 

Precision Engineering for Maximum Performance

Although the technical details of an engine stroker kit can be complex, the essential components include an upgraded crankshaft, connecting rods with an extended stroke, and pistons that may also feature an increased bore. The result is a more powerful engine with improved torque and higher RPM capabilities, making it an ideal upgrade for those looking to push their Subaru's performance to the next level.

 

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 Tomei 99.75mm pistons
• Fully forged connecting rods
• Fully forged crankshaft

 

 

NOTES:

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