High Performance camshafts is to suit the Version 6+ EJ20 engines with Subaru’s AVCS (Active Valve Control System).
This range of camshafts feature high velocity lobes that have a wider ‘sweep’ across the cam bucket, therefore these camshafts can only be used on shimless buckets or buckets that have the shim underneath. These profiles cannot run on the earlier 1999-2001 Version 5-6 buckets that have the shim on top.
EJ257B Dual AVCS 2008+ cams feature the same successful lobe designs used on the earlier engines. The Dual AVCS on this engine is a great tool for the tuner to provide a greater operating range. The Kelford range of camshafts feature a unique camshaft design technology called “ICE” or Improved Combustion Efficiency. This “ICE” split duration design has in turn created a significant combustion efficiency gain for these engines. No other aftermarket camshaft company offers this unique technology. Easily identified by the triggers on the rear of the cams.
Subaru FA20F engine is installed in WRX from 2015 Subaru models. Developed for a range of performance stages we have a cam set for every application, from street cars through to professional built drag cars.
