Wiseco Nissan VR38DETT 3.8L 95.58mm Bore 1.232inch CH -6.3 Dome Dish 9.5:1 Stroker Max HD Piston Kit

If you're building a high-performance Nissan GT-R engine, this Wiseco forged piston kit is designed to handle serious power. These pistons are specifically made for the VR38DETT 3.8L engine, with a 95.58mm bore and a 9.5:1 compression ratio, making them suitable for stroker builds and demanding applications. Wiseco builds these with 2618 aluminum, which offers improved tensile strength for the stresses of racing and heavy-duty use.

You'll find precision ring grooves on these pistons, along with features for additional ring seal, which helps maintain compression and prevent blow-by under extreme conditions. The anti-detonation grooves are there to help prevent pre-ignition. Wiseco also applies an ArmorGlide skirt coating to reduce friction, resist seizure, and help keep the engine running quieter. The fully machined crown ensures accuracy for optimal combustion chamber shape. These pistons also feature forced pin oiling to ensure the wrist pins stay well-lubricated, a critical detail for longevity in high-stress engines.

This kit includes everything needed to outfit a complete 6-cylinder engine. Remember, these pistons are not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper fitment and assembly procedures.
