Wiseco Nissan VR38DETT 95.50 mm Bore 34.30 mm CH -1.20 CC Piston Set

Starting with a 2618 aluminum forging, these Wiseco pistons are built for the demands of serious racing and heavy-duty performance applications. The material choice here is key, offering improved tensile strength over standard aluminum to handle the extreme pressures found in high-performance engines like the Nissan VR38DETT. Each piston is fully machined, including precision ring grooves, an anti-detonation groove, and other features designed to enhance ring seal and prevent detonation, which are critical for durability under severe duty. The ArmorGlide skirt coating further contributes to longevity by reducing friction and resistance to seizure, while also helping to quiet operation. This set is designed for builders who are pushing their engines to the limit and need components that can withstand severe stress and heat.

This set includes six pistons, each with a 95.50 mm bore and a 34.30 mm compression height. The piston crown features a -1.20 cc dish, which is a specific design choice that affects compression ratio when paired with your cylinder heads. Wiseco also incorporates forced pin oiling to ensure the wrist pin receives adequate lubrication, a small but important detail for maintaining the health of the rotating assembly under high loads. These pistons are a popular choice for builders looking for a well-built, reliable foundation for their performance engine builds, offering a robust solution for those who need their engine to perform consistently under extreme conditions.
