If you're building a high-performance Mitsubishi 4G63 or 4G64 engine, CP Pistons offers a forged piston set designed for serious power. This set, part number SC7265-4, is specifically made for the 4G63/4G64 2G and the Evo 8/9 platforms. It features an 87.5mm bore, which is a +1.0mm overbore size, and a 100mm stroke. These pistons are built to handle the demands of boosted applications and aggressive engine builds.

CP Pistons are well-known for their strength and reliability in performance circles. These pistons are forged from high-grade aluminum, a process that creates a much stronger and more durable component than cast pistons. This makes them ideal for engines that will see high cylinder pressures, high RPMs, and significant heat. The 87.5mm bore size is a common upgrade for these engines, allowing for increased displacement and improved airflow. The included rings are also selected to complement the piston's performance characteristics, ensuring a good seal and efficient operation.

This set includes four pistons, rings, and wrist pins, providing a complete solution for rebuilding or upgrading your engine's bottom end. It's important to note that these pistons are not CARB approved and cannot be shipped to California. Always consult with your engine builder or refer to manufacturer specifications for proper installation and assembly details, including required clearances and lubrication.
