Wiseco Mits Turbo DISH -17cc 1.378 X 86.5 Piston Shelf Stock

If you're rebuilding a Mitsubishi 4G63 engine, especially one destined for turbocharging, a solid set of pistons is crucial. This Wiseco piston is built for that purpose, featuring a -17cc dish volume and an 86.5mm bore size, designed to work with the 4G63 platform found in vehicles like the Mitsubishi Eclipse, Galant, and Lancer.

Wiseco is well-known for its forged pistons, and this one is no different. Forging creates a stronger, more durable piston than casting, which is important when you're adding boost. The -17cc dish helps to lower the compression ratio, making it a good choice for forced induction setups where you need to control cylinder pressures. The 86.5mm bore is a common size for these engines, and it fits right into the 4G63 block.

This piston is sold individually, so you'll need to order the correct quantity for your engine. Remember to check your specific engine's requirements and consult with your machine shop to ensure proper fitment and clearance during your build.
