Understanding the Technology Behind Mitsubishi Engines
What Mitsubishi Engines’ Technology (And Why You Should Buy Yours From Us) Is All About
Where technical superiority is Japanese, few names are more honored and venerable than Mitsubishi Motors. Famously producing tough, high-performance engines that are fitted in everything from mass transit weekday commuters to turbocharged rallying competition cars, Mitsubishi engines are the epitome of accuracy, ingenuity, and dependability. Understanding the Technology Behind Mitsubishi Engines
But what exactly makes Mitsubishi engines so trusted—both on the road and on the track? In this in-depth guide, we’ll break down the core technologies behind Mitsubishi engines, explore the specs of their most popular models, and explain why we’re your best source for new and rebuilt Mitsubishi engines.
Whether rebuilding a 3000GT, converting a Lancer Evolution, or simply replacing a tired engine in your Outlander, you’ll find it all here.
A Legacy of Innovation: A Brief History of Mitsubishi Engine Development
Mitsubishi’s post-war engine development history began in earnest and accelerated quickly in the ’70s, ’80s, and ’90s. Interestingly enough, Mitsubishi gained a reputation for:
- Turbocharging technology
- Multi-valve architecture
- Advanced electronic fuel management
- Motorsport-proven durability
By the 1990s, Mitsubishi engines—namely those in Lancer Evolution, Eclipse, and 3000GT vehicles—also dominated racing and tuner communities. Much of this is thanks to Mitsubishi’s emphasis on performance efficiency, stress reliability, and cutting-edge design that continues to apply today.
The Winning Mitsubishi Engine Technologies Uncovered
Now let’s dive deeper into the technological DNA that goes into developing Mitsubishi engines—namely those that we sell and rebuild.
1. DOHC (Dual Overhead Camshaft) Design
Most performance engines in Mitsubishi employ DOHC architecture, which increases airflow and efficiency through:
- More precise valve timing
- Higher redlines
- Improved volumetric efficiency
This layout is the norm for engines like the 4G63 and 4B11, giving them their signature responsiveness and top-end punch.
2. Turbocharging and Forced Induction
Turbo Mitsubishi engines like the 4G63T, 4B11T, and 6G72TT are equipped with:
- High-flow turbines
- Intercooling systems
- Precise wastegates and boost controllers
These motors are capable of delivering 300+ horsepower in factory configuration and much more with modifications.
3. MIVEC (Mitsubishi Innovative Valve Timing Electronic Control)
MIVEC technology adjusts valve timing for improved performance and fuel efficiency under different RPM conditions. The advantages are:
- Improved throttle response
- Lower emissions
- Improved fuel economy
MIVEC systems are found in motors like the 4B11, making them adaptable to both city driving and spirited acceleration.
4. Aluminum Blocks & Heads
Certain Mitsubishi engines utilize aluminum construction, which reduces the overall weight and allows for more efficient heat dissipation. This leads to:
- Lower engine bay temperatures
- Enhanced weight distribution
- Better efficiency and acceleration
These constructions are particularly useful in performance platforms like the Evo X and 3000GT VR-4.
5. Crank-Driven Oil Pumps and Forged Rotating Assemblies
Performance engines like the 4G63T come equipped with crank-driven oil pumps for high-RPM lubrication and forged steel crankshafts for pressure resistance.
During rebuilding or supplying new engines, we exercise special care for internals like these to offer longevity and reliability—whether for the street or racing.
