2.3L 16v - Duratec

FORD's 2.3 16v Duratec is the same block as Mazda's MZR: the parts below fit the Focus and the Mazda 3 alike. The range covers the bottom end and the valvetrain.

  • WOSSNER and WISECO forged pistons, bores from 87.5 to 90mm
  • SUPERTECH valves on a 5.48mm stem: 35 to 37.50mm intake, 30 to 32mm exhaust, in black nitrided stainless steel or Inconel
  • COMETIC reinforced head gasket, 89.5mm bore

Enough to make a naturally aspirated or a boosted Duratec build reliable.
