4G63 Meaning – The Ultimate Guide & Why Our 4G63 Engines are the Smart Choice
Introduction – It’s Not a Code: What 4G63 Really Means
If you’re a car enthusiast, tuner, or someone simply looking for a powerful replacement engine, chances are you’ve heard of the Mitsubishi 4G63. But what does 4G63 actually mean? Is it just a bunch of letters and numbers stamped on a block, or is there a story behind it? 4G63 Meaning
In fact, 4G63 is more than just an engine code—it’s the designation for one of the most iconic powerplants from Mitsubishi. For decades now, the 4G63 has been cherished for its capabilities in terms of strength, dependability, and performance. It’s motored everything from humble sedans to globe-conquering rally cars. 4G63 Meaning

Breaking Down the 4G63 Code
Mitsubishi has a certain naming convention policy for its engines, and 4G63 is no different. Let us decode:
- 4 – Represents the number of cylinders. In this case, it’s a four-cylinder engine.
- G – Gasoline engine (distinguished from diesel).
- 6 – Represents the family of the engine in the Mitsubishi G-series.
- 3 – Represents the model in that family.
So, 4G63 literally transcribes like this: Four-cylinder gasoline engine, 6th generation, 3rd generation. 4G63 Meaning
But that’s just the beginning—the real treasure lies in the history, design, and fabled performance heritage of the engine. 4G63 Meaning
The 4G63 Legacy – Street Cars to World Rally
The 4G63 originally debuted way back in the early 1980s in the Mitsubishi Galant as merely a tough, reliable 2.0-liter street rod engine originally. But Mitsubishi had something else planned. 4G63 Meaning
The Turbocharged Revolution
Mitsubishi launched the 4G63T, the turbocharged version of the engine, towards the end of the 1980s. The engine came with forged internals, a weighty iron block, and stoutly engineered cylinder head, hence becoming the tuner’s holy grail. 4G63 Meaning
Rally Dominance
The 4G63 powered the Lancer Evolution I–IX in some guise or another throughout the 1990s, and with it, they won many World Rally Championship rallies. Its balance of power-to-tune made it ideally suited for rallying’s brutal conditions—gravel, snow, tarmac, and everything in between. 4G63 Meaning
DSM Era
In North America, the 4G63T was the legend in Diamond-Star Motors (DSM) vehicles such as the Mitsubishi Eclipse GSX, Eagle Talon TSi AWD, and Plymouth Laser RS Turbo. They were street and drag strip legends. 4G63 Meaning
Today, over 40 years since its release, the 4G63 continues to be a tuner and restorer’s darling. And we sell them—ready to ship.
