The EVO X has become a favorite among tuners worldwide, with the 4B11T engine demonstrating surprising potential despite initial skepticism from fans of the legendary 4G63.

Engine Modifications

Basic Bolt-Ons:
- Intake upgrades (HKS or Blitz filters/airboxes)35
- Aftermarket intercoolers (ARC or ETS for improved cooling)12
- High-flow exhaust systems (Tomei, FGK, or custom setups)36
- ECU tuning (HKS F-Con, Cobb, or EcuTek for optimized performance)49
Serious Power Builds:
- Forged internals (pistons, rods, crankshaft) for engines targeting 400+ hp46
- Larger turbochargers (Precision 6262 or ETS 67mm for 500+ hp applications)27
- Fuel system upgrades (DW65C fuel pump, ID1000 injectors, and upgraded fuel rails)6
- Nitrous oxide systems for temporary power boosts (though rarely used daily)2
Extreme Builds:
- Engine displacement increases to 2.2L or 2.3L46
- High-lift camshafts (JUN 272° cams)6
- Fully built engines capable of 800+ hp with supporting modifications7

Transmission Options

Manual transmission swaps are popular in markets that only received the SST automatic, with complete GSR 5MT conversions becoming more common9. Strengthening the manual transmission with ORC twin-plate clutches or CM clutches rated for 1200hp ensures reliability under high power69.

Suspension and Handling

Coilover systems (KW V3, Ohlins DFV, or BC Racing with external reservoirs)36
Full chassis bracing (Cusco or Hardrace components)6
Upgraded bushings and spherical bearings for improved precision3
Wider wheels (18x10.5" or 19x11") with semi-slick tires (275-285 width)12

Braking Systems

While the stock Brembo brakes are capable, serious builds often upgrade to:

Endless or United Racing 6-piston front/4-piston rear big brake kits36
Carbon ceramic rotors for extreme applications7
Stainless steel brake lines for improved pedal feel2

Aesthetic Modifications

Popular styling choices include:

Varis, Chargespeed, or Voltex widebody kits17
Carbon fiber components (hoods, trunks, diffusers, and canards)15
Aggressive rear wings (Voltex GT or custom designs)23
"One-eyed" conversions replacing a headlight with an intake2
Air suspension for stance builds while maintaining daily usability10
