Wiseco Nissan VQ37VHR 95.58mm Bore .003 Oversize 88.39mm Stroke 3.5cc Vol 10.5:1 - Set of 6

If you're building a high-performance Nissan VQ37VHR engine, this set of six forged pistons from Wiseco is designed to handle serious power. These aren't your average pistons; they're built from 2618 aluminum, a material chosen for its improved tensile strength, making them well-suited for the demands of racing and heavy-duty applications. The bore size is 95.58mm, which is .003 inch oversize, and they feature an 88.39mm stroke with a 3.5cc volume, resulting in a 10.5:1 compression ratio. This specific compression ratio is a popular choice for many performance builds, offering a good balance between power and pump gas compatibility, depending on your camshafts and tuning.

Wiseco has packed these pistons with features to ensure durability and performance under extreme conditions. You'll find precision ring grooves, anti-detonation grooves, and other features designed to improve ring seal, which is critical for maintaining compression and preventing blow-by. The crown of each piston is fully machined for accuracy, and they include forced pin oiling to keep the wrist pins properly lubricated. Additionally, these pistons come with an ArmorGlide skirt coating. This coating helps reduce friction, making the engine run a bit smoother and quieter, while also providing resistance to seizure, a common issue in high-stress engine builds.

When you're putting together a severe-duty race engine, every component needs to be up to the task. Wiseco's Professional Series pistons are manufactured and machined in the USA, reflecting a commitment to quality and performance. They come with premium rings, ensuring a solid seal right out of the box. Keep in mind that these pistons are not CARB approved and cannot be shipped to California. For a robust VQ37VHR build, this set offers a strong foundation.
