CUSTOMER COMMENTS

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)

Paul, I am working on my 1870 conversion rebuild and admiring the quality of your overhaul kit. The JE Apple Bite pistons are absolutely beautiful and I would like to share that specs were spot on. The Hole Specific liners with beefed up walls are amazing. Head with oversize valves and cams ready to bolt on. So Happy for this. Cannot wait to take it to the dyno! EE USA

 

Available at this low price because parts in this overhaul kit are collectively discounted 10-15%.  SORRY.  NO DELETIONS, SUBSTITUTIONS OR RETURNS ON KIT COMPONENTS.

LINERS:  HOLE SPECIFIC….  These are machined from CENTRIFUGALLY CAST IRON that improves elasticity and reduces distortion caused by cylinder pressure.  The CYLINDER WALL THICKNESS has been greatly increased  for maximum strength. This lets the rings stay seated, maintains cylinder sealing and prevents drop of compression ratio at high rpm. Unlike soft still cast OEM liners, these NEW COMPETITION GRADE centrifugally cast iron alloy liners greatly increases strength and reduces bore distortion and decreases wear.

  • JE piston/liner set includes conventional rings, standard pins and wire locks. (SEE UPGRADE LIST)
