Product Details

The Wiseco K625M86AP is a 1400HD forged piston kit engineered specifically for the 1st Gen 6-bolt Mitsubishi 4G63 turbocharged engine. Featuring an 86.00mm (3.386 in.) bore with a -14cc dish, this kit is purpose-built for high-horsepower forced-induction builds and is compatible with E85 fuel.

Key Specifications:

  • Bore: 86.00mm / 3.386 in.
  • Stroke: 88mm / 3.465 in.
  • Compression Height: 35mm / 1.378 in.
  • Pin Diameter: 22mm (0.866 in.) — .225" wall tool steel wrist pins included
  • Head Volume: -14cc dish
  • Block Height: 229mm
  • Material: 2618 aerospace-grade aluminum alloy
  • Application: Mitsubishi 4G63 1st Gen 6-bolt, stock stroke

Key Features:

  • ArmorGlide® Skirt Coating — reduces friction and noise for improved efficiency and power output
  • Gas Nitrided Top Ring — optimized for turbocharged, high-boost applications
  • Napier 2nd Ring — provides excellent oil control under extreme conditions
  • Precision ring grooves with anti-detonation groove and enhanced ring seal features
  • Forced pin oiling for superior lubrication at high RPM
  • Specially designed valve pockets to accommodate oversized valves and high-lift camshafts
  • Optimized piston crown promotes intake charge efficiency through cross-flow scavenging
  • Engineered, forged, and machined in the USA at Wiseco's Mentor, Ohio facility

The 1400HD series was developed specifically for extreme high-horsepower 4G63 applications. The 2618 aluminum alloy forging delivers superior tensile strength and impact resistance compared to cast or billet alternatives, making it the preferred choice for heavily turbocharged DSM and Mitsubishi builds. The kit includes pistons, rings, and wrist pins — everything needed to complete your bottom-end assembly.

quick and easy

Quick and direct to my part

Best pricing I found for the K&N filter I needed and the order process was quick and easy. Shipping time is reasonable and I have absolutely no complaints.

Great prices!!

Recommended by a fellow RegalGS member. Cheaper than Amazon. I haven't had the opportunity to put them on yet, but everything looks good.

Website was super easy. Shipping remains to be seen.

My truck bed cover arrived today. Everything looks okay. Looking forward to installing it this weekend. <br> Thanks for the quick shipping.

Thanks

Excellent service - thank you!

Its amazing the prices Autoplicity is able to offer some of their products at. The product i ordered was consistently msrp on every site i searched through, yet autoplicity had it for $10 less. Lowest price along with a attractive and intuitive website is a win in my book. Having it shipped in less the 24hrs is another bonus

First experience so we'll see. So far it has been easy.

This was my first order with Autoplicity. I was pleasantly surprised when my order showed up quickly and was exactly what I wanted. I will be buying from this company again. Thanks for the quick service and fair pricing.

Great site! Just what I wanted!

a lot of their parts are the lowest price you can find. they will always be on my list of autopart dealers for every build
