O.S. Engines 12XZ Speed Spec II and 30 VG (P)

New from O.S. Engines:

By redesigning the 12XZ (P) Speed Tuned Spec II and 30VG (P) ABL, O. S. Engines® raises the bar for 1/10 and 1/8 scale racing engines. While the enhancements appear to be subtle, they can make all the difference when it comes to taking the checkered flag!

12 XZ (P) Speed Tuned Spec II:

  • Boasts excellent mileage and an improved bottom end
  • Holes machined into the aluminum outer head minimize overall weight and improve cooling
  • The crankcase and liner port have been designed to increase torque at low- to mid-range speeds
  • A special coating on the crankshaft reduces friction and wear
  • Tungsten weights offer better balance at high rpms

30VG (P) ABL:

  • An upgraded 21E slide-valve carburetor means easier tuning and more muscle for 1/8 scale monster trucks and truggies
  • Retrofits easily into .21 – .25 and .28 spaces with no modifications
  • Features virtually perfect bore-to-stroke balance with a rear-exhaust configuration
  • Designed with a 3-port Advanced Bi-Metallic Liner (ABL) cylinder liner for better compression and longer life
  • Oversized SG (pilot)crankshaft with rubber-sealed front bearing, plus an oversized rear bearing to handle high-torque loads

OSMG1991 12XZ (P) Speed Tuned Spec II $449.99
OSMG2076 30VG (P) ABL $259.99
