Product Details

The Wiseco 6655M89 is a forged performance piston set engineered for the Nissan SR20DET turbocharged engine. Featuring an 89mm bore diameter and a -17cc dish dome, these pistons are designed to work in conjunction with a K1 Technologies 92mm stroke crankshaft, making them an ideal foundation for high-displacement, high-boost SR20 builds.

Wiseco forged pistons are manufactured from aerospace-grade 2618 aluminum alloy, offering superior strength and thermal resistance compared to cast pistons. The forging process results in a denser, tighter grain structure capable of withstanding the extreme cylinder pressures generated in forced-induction applications.

Key Features:

  • 89mm Bore Diameter — precision-machined for consistent ring seal and reduced blowby
  • -17cc Dish Design — reduces compression ratio to accommodate forced induction and high boost pressures
  • Compatible with K1 Technologies 92mm Stroke Crankshaft — engineered for stroker SR20 applications
  • 2618 Forged Aluminum Construction — high strength-to-weight ratio ideal for turbocharged use
  • ArmorGlide Skirt Coating — reduces friction and improves piston-to-wall lubrication
  • Fully Machined Ring Grooves — precision tolerances for consistent ring seating and sealing

Designed for builders seeking a reliable, high-performance bottom end for Nissan SR20DET stroker applications, the Wiseco 6655M89 piston set delivers the durability and precision required for street, track, and competition builds.

They have the best prices on the net hands down. I saved 40 bucks buying through them and not only that but my item was shipped promptly. I would recommend using them i know im coming back.

This was my first purchase from Autoplicity, I bought a HyperTech tuner for my truck, they had absolutely the lowest price of anywhere I looked by far. Only thing I could fault them on is that it took 3 days for the product to ship, a little bit long I feel for something that was in stock, but Ill overlook it since it was such a great price.

user friendly site good price

Super quick and easy ordering through Amazon!

Recieved exactly what i wanted and and it only took 2 days to get here! will do business with again! A++++++

Autoplicity had the exact part I wanted at the best price upfront with no gimmicks or hidden conditions. Prompt shipping at a fair price. Simply excellent!
