We have been working with the people at JE on our pistons since 1978. Through our racing engine research and on track experience we have continuously modified our designs for better performance. We won four SCCA National Championships developing the same piston designs you can now buy off our shelf. Professional engine builders all over the world use our pistons.

Our 2000 Twin Spark piston is popular in Europe for both race and street. It fits all 8 valve engines and makes 10.5:1 compression and runs well on 93 octane pump fuel. The intake valve reliefs are enlarged for oversize 46mm valves and 3mm deeper intake & exhaust to clear performance cams.  The set includes standard wrist pins (109 grams) and rings.

• Compression of 10.5:1 is measured with standard head of .35mm height and 1.4mm Reinze gasket
• 3mm deeper valve reliefs accommodate most performance cams intake and exhaust
• Larger diameter intake valve reliefs will accommodate oversize 46mm intake valve.
• Standard 38mm exhaust valves are the best combination for power so exhaust reliefs are standard diameter

This piston set includes standard wrist pins (109 grams) and *Deves rings.  You should consider the following upgrades:

• Upgrade to light weight pins (77 grams) for an additional $60.00.
• Upgrade to Total Seal conventional ring set with ductile compression ring.  $27.00 extra (*the standard Deves cast compression rings can fail in high rpm engines that rev to 7500 and above).
• Upgrade to Total Seal gapless second ring set for more HP.  $129.00 extra.
• Upgrade to Total Seal gapless top ring set for even more HP.  $159.00 extra
  (check out HP gains at Total Seal HP Gains).
