Piston Set Nord 2000 84.0mm HOLE SPECIFIC 12.5 APPLE BITE DISH DOMES
[JE84HS12.5X2]
$747.00 $697.00

BIG HP GAIN COMPARED TO UNIVERSAL PISTON SETS.

"I build my last 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 2 Hole Specific Apple Bite Dish Dome Design maximizes combustion efficiency and power.  SET OF TWO PAIRS (#1/2 AND #3/4) WITH dish located under spark plug offsets of each chamber.

  • Lite weight underhead milling reduces weight to 395g.
  • 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.  $133.50 extra.
  • Upgrade to Total Seal gapless top ring set for even more HP.  $169.75 extra.  (Check out HP gains at Total Seal HP Gains).
