HKS BCD Piston Kit RB26 2.8L 86.5

This is the HKS BCD Piston Kit, specifically designed for the RB26 engine to bring it up to a 2.8L displacement with an 86.5mm bore size. If you're looking to build a more powerful RB26, forged pistons are a critical component for handling increased boost and stress. HKS has a long history with performance engine building, and this kit is a testament to that experience, offering a well-built solution for enthusiasts pushing their engines beyond stock limits.

The BCD (Big Capacity Displacement) series pistons are forged from high-strength aluminum alloy, making them significantly stronger and more durable than cast pistons. This strength is essential when you're increasing displacement and planning to run higher boost pressures, as it helps prevent piston failure under extreme conditions. The 86.5mm bore size is a common upgrade for the RB26, allowing for a larger displacement and the potential for more power. HKS includes all the necessary pistons in this kit, ready for your engine build. Remember, these pistons are designed for performance applications and require proper engine tuning to match the increased displacement and airflow.

When installing these pistons, it's important to ensure your engine block is properly machined to the correct bore size and honed for optimal ring seal. You'll also want to consider other supporting modifications like upgraded connecting rods, a performance crankshaft, and a robust engine management system to take full advantage of this displacement increase. Please note that this kit is not CARB approved and cannot be shipped to California.
