Product Description

SUBARU WRX EJ20 PERFORMANCE 2.1L STROKER ENGINE BUILD KIT MANLEY DROP-IN PISTONS

Stroker kits add displacement to your stock engine increasing power and torque.  Our ultra-high quality stroker packages provide reliability and value you won't find elsewhere.

This kit will not require boring of the engine block if 92 mm pistons are selected
however check with a qualified machinist before purchasing standard sized pistons for a used engine.  


When using 93 mm bore pistons, we strongly recommend installing new cylinder sleeves to make up for the loss of material from the +1 mm over bore.

Our 2.1 Liter EJ205 Manley stroker engine build kits include the following components: 

  • Forged 92 mm 92.5 mm or 93 mm Manley Platinum series 2618 alloy pistons from (8.5:1 C.R.)
  • New '430 Nitrided 79 mm OEM Subaru crankshaft
  • ACL Race series engine bearings
  • Manley Sport Compact H-Beam Rods

Please note: ACL/King Race Series Standard oil clearance mains and +.001 rod bearings will be supplied with this kit
