Piston Liner Set 74mm 1290cc Kit 12:1
[753074]
$985.00

FIA Legal 1290cc for 1300cc class limit.

5 HORSE POWER GAIN!

This 12:1 oversize bore kit increases displacement from 1290 to 13.  The increase in compression to 12:1 adds another 5 HP, bringing the total gain to an estimated 9 HP. A stock 1300 twin weber engine goes from 112 HP to 126 HP. This makes a significant difference in performance. This kit comes with standard rings and pins. No standard pins available. No modification to block necessary.

These liners are new74mm 1300 liners. They are true to .001" for taper and out of round. They are fitted to our 74 mm pistons at .003" to .0035"

This piston set includes standard wrist pins (84 grams) and *Deves rings.  You should consider the following upgrades:

  • Upgrade to light weight pins (62 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).

If we do not stock the appropriate compression piston for your engine needs, we will be delighted to help you with a special order set. We also sell single pistons and pins if you damage one and need a spare.  Please call us for more information. 1-800-552-ALFA.
