OVER 50 HP GAIN?

This 2mm overbore increases displacement from 1779 to 1870cc.  With this 5% increase in displacement, raising compression from 9.5 to 10.5:1 and HOLE SPECIFIC APPLE BITE domes makes a huge difference in both street performance and race engines.  With stock head, cams and exhaust, a Weber carbureted engine typically steps up from 132 to about 145 HP with no compromise in reliability/drivability.  Good headwork, cams and headers can easily make 155-165.  Full race prep can be “Astounding.”

APPLE BITE DISHED DOMES offset from piston center makes more power with flame front travel distance absolutely minimized.  With compressed charge concentrated directly under spark plugs, the conbustion efficiency is vastly improved.  Also, the fat sides of the dame “squash” the mixture at TDC creating a hurricane to distribute the flames.

  • Lite Weight
  • Compression of 10.5:1 is measured with standard head of 112mm height and 1.4mm Reinze gasket.
  • Deeper valve relief to accommodate most performance cams.
  • Larger diameter valve reliefs will accommodate oversize 42.5mm intake and 38mm exhaust valves.

We also offer these as Piston/Liner Sets.

CUSTOMER COMMENT:

Hi Paul, This 1900 kit is astounding,.  Just like you said, it performs like a 2L.  The guy at the dyno could not believe it made 190.  I really appreciate you walking me through this two year race prep project.  BG, CA
