4G63 Engine in Phoenix, Arizona
A rally-derived turbocharged four with a long production run, and a family code that covers engines of wildly different value.
- Family
- 4G63 (4G6-series)
- Displacement
- 2.0 L
- Configuration
- Inline-four
- Valvetrain
- DOHC, 16 valves
- Produced
- 1980s–2007
Bore and stroke are omitted for this family: the code covers variants with different figures, and a single pair of numbers would be wrong for some of them.
The 4G63 is a 1,997 cc inline-four from Mitsubishi’s 4G6 family, and while it appeared in a wide range of naturally aspirated applications, the version people search for is the turbocharged 4G63T used in the Lancer Evolution I through IX between 1992 and 2007.
The Evolution engine is a specific, high-specification build with a forged rotating assembly, and it carries a price to match. Naturally aspirated 4G63 units from ordinary Mitsubishi and Eagle/Plymouth models are a different proposition entirely and should not be confused with it in a listing.
The 4G63T also appeared in the Diamond-Star Motors cars, the Eclipse, Talon and Laser, in the early 1990s, which is the other common source of these engines in the United States.
Almost all 4G63T demand here is for builds rather than repairs, which puts the ECU, the turbocharger, the fuel system and the supporting hardware squarely in scope alongside the engine itself.
Evolution, DSM and naturally aspirated are three different purchases
The Lancer Evolution 4G63T is a high-specification build with a forged rotating assembly, and it is priced accordingly. The DSM-era 4G63T from the Eclipse, Talon and Laser is a turbocharged 2.0 four with the same code and different internals. Naturally aspirated 4G63 units from ordinary Mitsubishi models are a different proposition again.
All three appear in listings as "4G63". Establishing which one is on offer is the first question, not a detail. The value spread across those three groups is larger than the price of most complete engines.
What a 4G63T project actually needs
Almost all demand for this engine in Phoenix is for builds rather than repairs, which means the engine is one line in a longer budget. Fuel system, intercooling and engine management have to be planned as a package alongside the turbocharger itself.
The 4G64 is worth knowing about too: it is a 2.4-litre relative in the same family, sometimes used as the basis for a stroker build, and sometimes confused with the 4G63 in listings. It is a different engine.
Vehicles built with a 4G63
The Lancer Evolution line plus the Diamond-Star Motors cars, which are the other common US source for these engines.
| Vehicle | Years | Trim / body | Engine code | Market |
|---|---|---|---|---|
| Mitsubishi Lancer Evolution | 1992–2007 | Evo I–IX | 4G63T | JDM |
| Mitsubishi Eclipse | 1990–1999 | Turbo | 4G63T | USDM |

4G63 variants
Three broad groups. The Evolution units are a genuinely different build from the DSM-era turbo engines, and both differ from the naturally aspirated versions.
- 4G63T (Evolution)JDM
- Turbocharged Lancer Evolution specification, I–IX. Forged rotating assembly.
- 4G63T (DSM)USDM
- Turbocharged Eclipse, Talon and Laser applications.
- 4G63 naturally aspiratedBoth
- Non-turbo specification across a range of Mitsubishi models.
Identifying a 4G63
- Turbocharged 4G63T and naturally aspirated 4G63 units are physically distinguishable by the turbocharger and manifold arrangement.
- Evolution-specification engines differ from DSM-era 4G63T units in internals and supporting hardware despite the shared code.
- The 4G64 is a 2.4-litre relative in the same family and is a different engine.
A seller describing an engine as a particular variant is making a checkable claim. Asking for a photograph of the stamp on the actual unit is not a sign of distrust; it is the normal way this gets confirmed. The engine code guide shows where each family is stamped if you want to read the one in your own car first.
What varies between 4G63 units
These are the differences that decide whether two engines with the same family code are substitutes in a particular car.
- Evolution and DSM 4G63T units are not equivalent; confirm which generation a listing describes.
- Turbocharged builds need the fuel system, intercooling and engine management planned as a package.
- Almost always a swap or a build rather than a like-for-like replacement.
- Timing belt driven; belt and water pump belong in the installation budget.
Nothing on this page confirms that a specific 4G63 will work in your vehicle. That takes the year, model and trim at one end and a specific unit at the other, and it happens before a price is given rather than after. What goes into that check is set out here.

Common questions
Is an Evo 4G63T the same as a DSM 4G63T?
No. Both are turbocharged 2.0-litre 4G63 engines, but the Lancer Evolution units are a higher specification with different internals and supporting hardware, and they are priced accordingly. A listing that says only "4G63T" has not told you which one it is.
