EASY 20 HP STREET PERFORMANCE GAIN!  MUCH MORE FOR RACE!

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 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 150 HP with no compromise in reliability/drivability.  Good headwork, cams, Weber 45’s and headers can easily make 160-185.  Full race prep can be “Astounding.”

Available at this low price because parts in this overhaul kit are collectively discounted 10%. SORRY, NO DELETIONS, SUBSTITUTIONS OR RETURNS ON KIT COMPONENTS.

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  (FULL RACE PREP 11.5:1)
