Wiseco Nissan VQ37VHR 95.5mm Bore Std Oversize 86mm Stroke 2.7cc Vol 11.5:1 - Set of 6

If you're building a high-performance Nissan VQ37VHR engine for serious racing or demanding street use, Wiseco's Professional Series forged pistons are a solid choice. These aren't your average pistons; they're designed from the ground up to handle the extreme stresses of competition, offering improved strength and durability where it matters most. Wiseco machines these pistons in the USA from 2618 aluminum, a material known for its high tensile strength, making them well-suited for heavy-duty applications.

You'll find precision in every detail, from the anti-detonation grooves that help prevent pre-ignition to the specific ring groove design that ensures better sealing. They also feature an ArmorGlide skirt coating, which is designed to reduce friction and resist seizure, contributing to a quieter operation and longer piston life under load. The crown is fully machined for accuracy, and the design includes forced pin oiling to keep the wrist pin well-lubricated, a critical factor in high-RPM, high-stress engines.

This set includes six pistons, each with a 95.50 mm bore and a 2.7cc volume, resulting in an 11.5:1 compression ratio. This compression ratio is ideal for naturally aspirated builds aiming for maximum power, or for boosted applications where careful tuning can manage detonation. 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.
