Piston Set Nord 2000 85mm FOUR-HOLE SPECIFIC 12.5:1 APPLE BITE DOME LITE WEIGHT
[JE85HS12.5X4]
$987.00 $797.00

HUGE HP GAIN OVER UNIVERSAL PISTON SETS.  FULL RACE PREP CAN MAKE OVER 200.

CUSTOMER COMMENT:

"I build my last race race 2 ltr Engine with your JE 12,5 apple bite pistons.  I'have never seen a engine before, which have such an amazing Torque curve on dyno graph.  J.E., Germany

Our new 4 Hole Specific Squish Dish Design maximizes combustion efficiency and power.  SET OF FOUR CUSTOM FITTED PISTONS, with both valve reliefs and spark dish located to the valve and spark plug offsets of each chamber.

  • Underhead milling reduces weight to 350g.
  • Flame front travel distance is minimized and charge is concentrated directly under spark plugs to improve combustion efficiency.
  • Tall shoulders of dome "squash" the mixture at TDC creating a hurricane to distribute the flames.
  • These hole specific domes clear heads with up to 1.0mm removed.  
  • Deeper valve reliefs accommodate most race cams.
  • Larger diameter valve reliefs will accommodate oversize 46mm intake and 41mm exhaust valves.
  • Compression of 12.5:1 is measured with standard head of 112mm height and 1.4mm Reinze gasket.   WARNING:  25mm milling = +.25:1 increase in compression.  Also, be aware that valve shape/size, seat height and reshaping chambers can make a big difference.  For absolute accuracy, customer should submit head chamber volume.

This piston set includes standard wrist pins (100 grams) and conventional Ring Set. 

YOU SHOULD CONSIDER THE FOLLOWING UPGRADES.  (Specify Upgrades in "Customer Comments Box" when ordering on line from website):

  • Upgrade to light weight pins (80 grams) for an additional $80.00.
  • Upgrade to Total Seal gapless second ring set for more HP.  $133.00 extra.
  • Upgrade to Total Seal gapless top ring set fo even more HP.  $166.00 extra.  (Check out HP gains at Total Seal HP Gains).
