Racing Performance Works 4G15 Stroker Kit
This stroker kit includes the following

  • CP Forged Piston Set – factory compression ration
  • Brand new crankshaft assembly – 87.30mm stroke (Factory 4G15 is 82mm)
  • Forged conrod set – resized length to suit the stroker crankshaft
  • ACL Conrod and Main Journal bearings.
  • There is the choice of three different piston sizes from standard to 1.00mm Oversize.

This package will take the capacity of the engine from the factory 1468cc to 1540cc.
This provides significant benefits being

  • Increases in low to mid range torque levels
  • Decrease in turbo lag
  • Ability to run a larger turbo without any increase in turbo lag over factory (Depending upon turbo size)
  • Improvements in upper power ranges
  • Peak power is produced at a low rpm between 500 – 1500 rpm depending upon which camshaft is used.

The only modifications required will be slight modifications to the sump pan for additional clearance where the conrods can touch.

NOTE : Due to supply chain issues the total price can only be calculated once items have been manufactured as many are custom made items only (Usually pistons etc) – pricing is indicative only
