Engine OH Kit RACE/STREET 2000 TWINSPARK PERFORMANCE BOTTOM END 85mm (See Details for Compression)
$1,550.00 $1,295.00

NEW!  ASYMMETRICAL DESIGN.  This slipper skirt piston type design features:

  • This intake shirt is 20% narrower than a fukl skirt, rod angularity creates greater pressure on the intake side load before TDC.
  • The compression decay after TDC reduces the exhaust loading allowing a 40% reduction on the exhaust skirts.


I am working on my rebuild and admiring the quality of the parts in your overhaul kit.  The J&E pistons are absolutely beautiful and I'd like to share the specs were spot on.  I couldn't measure any variation between them and they fit the liners perfectly to spec.  The liners were very true with .0003 being the largest variation I could find.  So happy for this.  EE, USA


  • JE piston/liner set includes conventional rings, standard pins (100 Grams) and wire locks. 
  • Reinze bottom end gasket set (quality German Mfg)
  • Rod and main bearings-standard (oversize available extra)
  • Upper and lower Iwis race/street chains
  • Thrust Washers
  • Locktag Kit
  • Hardwqare Kit 25 each:  8 & 6mm nuts & spring washers


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

  • Our rebored liners are sold on an EXCHANGE basis.  However, you must send your core liners in advance of shipment.  Sorry, but we have to do this because 90% of customers never return cores.
  • NEW COMPETITION GRADE LINERS available.  Upgrade $345. (Specify upgrade in "Customer Comment Box."
  • Upgrade to super strength Ductile Iron Liners $485.  Centrifically cast iron greatly increases strength and reduces wear.  (Specify upgrade in "Customer Comment" Box.)


You should consider the following:

  • Upgrade to light weight pins (77 grams) for an additional $80.00.
  • Upgrade to Total Seal gapless second ring set for more HP.  $132,59 extra.
  • Upgrade to Total Seal gapless top ring set for even more HP.  $169.75 extra.  (Check out HP gains at Total Seal HP Gains).
