14 HORSE POWER GAIN!

This 10.5:1 oversize bore kit increases displacement from 1570 to 1690cc. This 7.4% increase in cylinder volume increase HP 7.4. The increase in compression to 10.5:1 adds another 5 HP, bringing the total gain to an estimated 14 HP. This makes a huge difference in performance. This kit comes with standard rings and pins. No modification to block necessary.

• My personal Giulia Super was converted in 1985 and is still running strong when it gets out on the road. Euro 1750 cams recommended.

These liners are rebored from good core 78mm liners. They are true to .001" for taper and out of round. They are fitted to our 81 mm pistons at .003" to .0035"

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
