Product Description
Details
The Tomei SR22 stroker kit for the SR20 engine increases the Engine capacity and strength for increased torque and potential power output.
The engine displacement increase is made possible with the forged full counter crankshaft that has an extended 5mm stroke design abd also comes with Forged Pistons.
Tomei has made an option to include their Competition Bearings. All the engine internals are brought to static temperature (20 degrees Celcius) and blueprinted with 0.040~0.060mm clearance bearings. This eliminates the measuring and blueprinting process for the customer, so the kit can be installed with less hassle.
