Mitsubishi 7-Bolt 4G63 Sport Compact 1400HD Pistons by Wiseco

Own a 7-Bolt 4G63 engine and plan on building a motor? Wiseco is proven to make some of the best pistons on the market!

Featuring valve pocket designs that allow maximum flow around valve, also allowing oversized valves and high lift cams to be utilized and piston crown shapes designed to promote maximum intake charge efficiency thru scavenging mixture "cross flow" during intake and exhaust valve overlap. More fuel and air equals more horsepower!

Their pistons are designed to optimize squish or quench during compression combustion cycle event, resulting in resistance to detonation and pre-ignition. The end product is longer engine life and increased horsepower potential.

Great Product

Exactly what you would expect, prompt shipping.

Best pistons money can buy

I know many people that have made some serious power on these pistons. I ordered the 85.5mm ones that way I can have the block bored out slightly to ensure a straight bore and I got exactly what I ordered very quickly.

Luis Vazquez

Was on back order but it’s alright . Wiseco 1400hd has been proven to be one of the best for this platform 🤟🏻
