The WSRD Stage 4 Camshaft by BC Racing is only intended for “fully built” engines with larger turbo(s), CNC ported cylinder head, MoTeC or equivalent ECU, etc... This will require the BC Race Duner or Drag valve spring & retainer kit. WSRD ECU tuning, cylinder head work, intake/exhaust are mandatory for optimal gains.
