The Tomei 4B11 2.3 Stroker Kit is engineered to upgrade the Mitsubishi Evo X's 4B11 engine, increasing displacement to 2.3 liters for improved performance characteristics. Key components include a precision-balanced crankshaft with shaped counterweight edges and an X-type 2-line oiling system, subjected to high-precision quality control. The forged pistons are designed for light weight and high rigidity, featuring a thin ring design to reduce friction and compatibility with standard and 1mm oversized valves. They also offer optimal oil jet clearance. The kit also contains robust H-beam connecting rods, noted for their gradually slanted design to maximize rigidity. These rods are equipped with large diameter dowel pins and two oil ports on the piston side for enhanced lubrication. High-tensile ARP L19 connecting rod bolts are included for secure assembly. Detailed specifications include a bore of 87.00mm (STOCK +1.0), a stroke of 98.00mm (STOCK +12.0), resulting in a displacement of 2330.3cc. The CC volume is 49.0cc, with piston deck clearance at ±0.0mm and a piston compression height of 27.40mm (STOCK -6.0). Rod center-to-center length is 143.80mm (STOCK ±0.0), and the head gasket bore is 87.5mm. This stroker kit is specifically designed for the 2008-2015 Mitsubishi Evo X models. It comes with all necessary pins, rings, and clips for the pistons.
