Mitsubishi Lancer Evolution IV (CN9A) 1996–1998 Performance Parts & Upgrades

The Mitsubishi Lancer Evolution IV (CN9A) was built from 1996 to 1998 and reached Australia as a Japanese import, in GSR and lighter RS form. It uses the 2.0L 4G63 turbo four with all-wheel drive, and its chassis carried on into the Evo V and VI (CP9A). This page lists the parts we stock for the Evo IV, from GSC Power-Division camshafts and valvetrain and Nitto 4G63 internals to HARDRACE arms and bushings, GFB and Turbosmart blow-off valves, Radium fuel parts and Alcon, Brembo and AP Racing big brake kits.

Popular upgrades for the Evo IV
  • Engine: GSC Power-Division camshafts, valves, guides, springs, retainers and lifters, Nitto crankshafts, rods, pistons and gaskets, and ARP head studs for 4G63 builds.
  • Turbo and boost: GFB and Turbosmart blow-off valves, a GFB wastegate actuator and a Tomei exhaust manifold.
  • Suspension: AST and Öhlins coilovers, HARDRACE rear lower control arms, toe arms, stabiliser links and roll centre adjusters.
  • Brakes: Alcon, Brembo and AP Racing big brake kits and Paragon front rotors.
  • Fuel and cooling: Radium fuel rails, hangers, filters and catch cans, Injector Dynamics injectors, a Koyorad radiator and Mishimoto silicone hoses.
Choosing the Right Part
  • GSR or RS: the RS came with smaller brakes than the GSR on some cars. Check your calipers and rotor size before ordering brake parts.
  • Evo IV or later Evo: many 4G63 parts fit Evo IV to IX, but some arms and links are made for the CP9A or CT9A only. Check the chassis codes in the title.
  • Age and past repairs: most Evo IVs have had work done by earlier owners. Check what's fitted to your car, such as the turbo and fuel system, before you order matching parts.
Installation

Have a qualified workshop fit engine, suspension, brake and fuel parts. Get a wheel alignment after any suspension change, and bleed and road-test the brakes after brake work. Engine, fuel and boost changes need a tune to suit.
