If you're rebuilding the engine in your Nissan GT-R, especially if you're looking to push its performance further, a strong set of pistons is key. This Manley piston is built for the 3.8L GT-R engine, featuring a 95.5mm bore and a 9.8:1 compression ratio, designed to handle the demands of a performance build.

Manley uses domestic 2618 alloy forgings for these pistons, which means they're well-built and strong enough for serious engine work.
