Mitsubishi Lancer Evolution IX
The final and most refined evolution of the venerable 4G63T-powered Evo lineage, the Evo IX added Mitsubishi's MIVEC variable valve timing to the aging engine architecture, squeezing out more power and broader torque before the nameplate moved to an all-new engine for the Evo X.

History
By 2005 the 4G63T had been in continuous production and refinement since the original Evo I, and the Evo IX represents its final, most sophisticated form before Mitsubishi retired the engine in favor of the Evo X's new 4B11T powerplant.
Why It Became Famous
It's celebrated as the swan song of the legendary 4G63T engine — the most refined version of an engine platform with over a decade of continuous racing and tuning development behind it.
Strengths
- MIVEC variable valve timing broadens the powerband versus earlier 4G63T Evos
- Represents the most refined, sorted version of the entire 4G63T Evo lineage
- Huge, mature aftermarket support built up over more than a decade of 4G63T tuning
- Available MR trim adds a six-speed gearbox and sharper suspension tuning
Weaknesses
- Never sold new in North America, requiring import in that market
- Heavier than earlier Evo generations, slightly dulling outright agility
- Values have risen as it's recognized as the final and most desirable 4G63T Evo
- Same fundamental turbo and head gasket wear concerns as other 4G63T Evos
Common Problems
- 4G63T turbo and head gasket wear, especially on aggressively tuned examples
- MIVEC solenoid wear affecting variable valve timing function
- AWD system and AYC differential wear if maintenance is neglected
- Rust in typical mid-2000s Japanese sedan problem areas
Modification Potential
About as strong as it gets for the 4G63T platform — over a decade of aftermarket development means big turbo kits, built engines, and drivetrain upgrades are all extremely well documented and proven.
Buying Guide
Verify MIVEC and turbo system health, check whether it's the standard trim or the sharper MR variant, and confirm import documentation if buying outside Japan.
Enthusiast Popularity Today
Beloved by Evo and 4G63T purists as the definitive, final version of the platform, with values reflecting its status as the end of an era before the Evo X's new engine.
Fun Facts
- The Evo IX was the last Evo to use the 4G63T engine, ending a lineage that began with the original 1992 Evo I
- MIVEC (Mitsubishi Innovative Valve timing Electronic Control) improved both low-end torque and high-rpm power over earlier non-MIVEC Evos
- It's frequently cited by tuners as the most track-ready, well-rounded 4G63T Evo ever produced
More from Mitsubishi
Mitsubishi Lancer Evolution I
1992–1994 · 244 hp · AWD
The original Lancer Evolution took an ordinary compact sedan and stuffed in a serious turbocharged AWD rally weapon, kicking off a nameplate that would spend the next two decades trading blows with Subaru's WRX STI for World Rally Championship glory.
Mitsubishi Lancer Evolution III
1995–1996 · 266–270 hp · AWD
The Evo III sharpened the formula with genuine aerodynamic addenda (a larger front bumper intake and rear wing) developed from Mitsubishi's rally program, and a revised 4G63T that pushed power notably higher than the original Evo I/II.
Mitsubishi Lancer Evolution V
1998 · 276 hp · AWD
Wider, more aggressive, and genuinely track-focused, the Evo V introduced a wider track and Mitsubishi's Active Yaw Control (AYC) rear differential, a genuine torque-vectoring system that dramatically sharpened the car's cornering ability.
