Wiseco ZRP 1400HD forged pistons for Toyota Supra 3.0L 2JZ Bore - 86.25mm 9.0:1

ZRP, in collaboration with Wiseco, has created a new and exclusive series of pistons manufactured in the USA using 2618 alloy. These pistons share many advanced features with the Wiseco HD1400 series for extremely high-horsepower setups.

They include upgraded wrist pins with a 5.34 mm wall thickness and Armor Plating to reduce the negative effects of intense heat in turbocharged and nitrous/methanol setups. Each ZRP piston for this application incorporates an ArmorGlide anti-friction skirt coating to minimize wear during break-in and reduce friction on the cylinder wall. Our pistons are manufactured using proprietary forgings, providing a lightweight piston with superior strength and optimal design. Additionally, valve pockets are larger and deeper than those of OEM pistons to accommodate high-lift camshafts. Furthermore, the pistons feature offset wrist pins and anti-detonation and gas pressure grooves to extend ring life.

What is Armor Plating?

Armor Plating gives them a bronze tone on the top and in the piston pin bore. This abrasion-resistant coating increases the hardness of the aluminum, improves ring groove durability, prevents piston ring micro-welding, reduces carbon buildup, and fights detonation corrosion. Additionally, Armor Plating reduces piston crown temperature by an average of 20 °C.

What is the ArmorGlide anti-friction skirt coating?

The ArmorGlide piston skirt coating is made with a molybdenum solid-film lubricant and permanently adheres to the pistons. One of its main features is scuff resistance and friction reduction, which ensures quiet operation. Of course, piston rock and noise are reduced, and horsepower is increased.
