21XZ-B Speed Spec II Gold Edition Engine


The 21XZ-B Speed Spec II has set the gold standard of 1/8 scale racing engines. Now, it’s available in a special Gold Edition to commemorate O.S.’s 80th anniversary.

A gleaming gold cylinder head and carb insert makes it extra-attractive for collectors, while the legendary O.S. performance makes it a must for high-octane racing!

  • A lighter crankshaft, with DLC coating, Tungsten weighting and silicone-filled intake passage
  • Modified piston and con rod that reduces overall weight
  • Outer head with V-shaped fins for lower CG and more efficient cooling.
  • Dual-adjustable 21J carburetor for smoother acceleration and better fuel mileage
  • Available with or without the T2090SC pipe set.
