Description

Product description

The era of direct injection engine overcharging is coming!

The 2.1L KIT for the FA20 has been added to the low comp specification for high overfeeding.

Many people have installed a supercharger on the FA20.

They developed the strong low comp piston that would be required for the next time they are going to high hyperhydration.

Features

POINT-1 Piston Kit

• Forged material for added strength
• The crown has a cavity for optimal atomization of direct spray.
• 3D shaping for continuous tumble flow of the crown
• Recessed shape assumes the use of HKS camshafts.
• Gasket selection has expanded the range of compression ratio settings.
• Uses molybdenum coat to reduce friction

POINT-2 Stovetop

STEP1

• With the long stroke, the dedicated cocking rod has been set. The engine side processing is eliminated, and the crank pin size has been specially sized.
  You will need to purchase a separate metal (for Nissan RB26 & SR).
• The high strength I cross section shape is optimized to redefine the conrod bolt size.

STEP2

• By using strength analysis, the thickness of the wall is optimized, and the weight gain is minimized and the strength is approximately 30%.
• Adopts an I-section shape that focuses on improving bending strength.
• The perfect shape without snag, and the surface is completely shaved to eliminate the starting point of damage on the surface, and the surface has been treated with a powerful shot peeling process to increase the fatigue strength.
• Optimal heat treatment for chrome-molybdenum steel provides both strength and toughness.

POINT-3 Crankshaft Stroke 90.0mm

• Forged material crank.
• Set your own pin journal size. This is a set with Con Rod.
