ENGINE BLOCK COMPONENTS

For RB users that require more low and mid rpm torque, the RB26DETT 2.8L kit is ideal. Step Zero, Step 1, and Step 2 are available to suit the specifications of each user.

STEP ZERO

  • Piston: Used the forged material from high specification.
  • Connecting Rod: Used the forged material from high specification with H-beam design for maximum strength and durability. WPC shot-peening also contributes to strength as well as preventing metal fatigue.
    * Stock rods can also be used.
  • Crankshaft: Used the forged material from high specification and fully counterweighted for best engine response. Intended rpm can be optimized for selected turbine.
  • Ideal kit when overhauling from standard internal parts

More information of STEP ZERO

STEP1

  • Piston: Used the forged material from high specification
  • Connecting Rod: Used the forged material from high specification with H beam design for maximum strength and durability. WPC shot peening also contributes to strength as well as preventing metal fatigue.
    * Stock rods can also be used
  • Crankshaft: Forged form high specification material and fully counterweighted for maximum balance at high rpm.
  • Best used with GTIII-RS (Target rpm is 8500rpm).

STEP2

  • Piston: Forged piston with Nickel plating for anti-knocking properties and top piston ring stability. Piston Skirt is molybdenum coated for friction reduction, clearance optimized and smoother bedding in new.
  • Connecting Rod: Used the forged material from high specification with H-beam design for maximum strength and durability. WPC shot peening also contributes for strengthening as well as preventing metal fatigue.
    * Stock rods can also be used.
  • Crankshaft: Used the forged material from high specification and fully counterweighted for maximum balance at high rpm. Pin journals and center has been hollowed to lighten the rotating mass to improve the throttle response.
  • Best if used with GTIII-RS, GTIII-4R etc. (Target rpm is 9000rpm).
