What engine is in the Dodge Stealth?
The Dodge Stealth is powered by a 3.0-liter Mitsubishi V6. In base form it uses the naturally aspirated 6G72 engine, while the high-performance RT/Turbo models use a twin-turbo version of the same family (6G72TT), delivering substantially more power. These engines were shared with the Mitsubishi 3000GT, as the Stealth was the Dodge-branded variant of that car.
Produced from 1991 to 1996, the Stealth offered two main engine configurations: a naturally aspirated 3.0-liter V6 for standard models and a twin-turbo 3.0-liter V6 for the higher-performance variants. The engine codes are 6G72 for the NA version and 6G72TT for the turbocharged version, with the turbo setup delivering noticeably more horsepower and torque. This alignment with Mitsubishi’s 3000GT lineup is a key part of the car’s identity and maintenance considerations.
Engine configurations across the Stealth’s life
Below is a concise breakdown of the two engine configurations that powered the Dodge Stealth during its production years.
- 6G72 — 3.0-liter V6, naturally aspirated (NA). Used in base Stealth models; typical output around 160–190 horsepower depending on year and market.
- 6G72TT — 3.0-liter twin-turbo V6. Used in Stealth RT/Turbo variants; typically around 320 horsepower, with substantial torque, thanks to the twin-turbo setup.
Both engines are part of Mitsubishi’s 6G72 family and were paired with a similar drivetrain philosophy to the Mitsubishi 3000GT, contributing to shared maintenance considerations and parts compatibility across the two brands.
How the engines differ in performance
The naturally aspirated 6G72 provides smooth, low-to-midrange power suitable for everyday driving, while the 6G72TT twin-turbo setup delivers significantly more peak horsepower and a stronger mid-range surge. Turbo models also incorporate intercooling and a more complex turbocharger system, which affects maintenance needs and boost behavior. The core architecture is the same family, but the turbo version is tuned for higher output and higher stress on components such as the exhaust, cooling system, and intake paths.
NA 6G72 vs Turbo 6G72TT: Key differences
The main differences lie in forced induction (turbocharging vs. natural aspiration), horsepower/torque output, and the associated supporting systems (turbochargers, intercooler, exhaust tuning, and cooling requirements). This means the turbo cars typically require more attentive maintenance—especially around the turbochargers and intercooler—than the NA cars, and they deliver a distinctly more aggressive driving experience.
Maintenance and ownership notes
Because the Dodge Stealth shares its engines with the Mitsubishi 3000GT, many parts are interchangeable or compatible, which can ease sourcing for both NA and turbo variants. Turbo models demand extra attention to oil quality and changes, cooling system condition, and the turbo plumbing. When evaluating a used Stealth, inspect for turbo wear, intercooler leaks, and signs of boost-related issues, and verify service history for timing/drive components as recommended by the manufacturer’s guidelines of the era.
Summary
The Dodge Stealth’s engine lineup centers on two Mitsubishi 6G72-based configurations: a 3.0-liter naturally aspirated V6 for base models and a 3.0-liter twin-turbo V6 (6G72TT) for the high-performance RT/Turbo variants. This split defines the car’s performance envelope and maintenance considerations, reflecting its close ties to the Mitsubishi 3000GT lineage. Whether you’re seeking a smooth daily driver or a turbocharged classic, understanding these engine differences is essential for ownership and restoration decisions.
Is the Dodge Stealth a rebadge?
Is that real? Absolutely. In the 1990s, before Dodge rediscovered its muscle car roots, its top-of-the-line sports car was a rebadged and restyled Mitsubishi 3000GT.
What engine does a Dodge Stealth have?
3.0-liter V-6
The Mitsubishi-engineered Dodge Stealth R/T Turbo is powered by a twin-turbocharged and intercooled, 24-valve 3.0-liter V-6 that produces 300 horsepower. The ZX Turbo comes with anti-lock brakes and four-wheel steering. The Stealth comes with anti-lock brakes and four-wheel steering.
Is the Dodge Stealth RT twin turbo?
There are very few cars that can tout the fact that it has a twin turbo engine setup, all-wheel drive and all-wheel steering as an option.
Is the Dodge Stealth just a 3000GT?
Yes, the Dodge Stealth and the Mitsubishi 3000GT are essentially the same car, developed through a partnership between Chrysler and Mitsubishi and sold under different brands in North America. The Dodge Stealth is a rebadged version of the Mitsubishi 3000GT, with the Stealth featuring different front-end styling and some interior trim variations, but sharing the same underlying platform and mechanicals.
- Platform: The cars were co-developed and built on the same platform by Mitsubishi.
- Branding: The Mitsubishi 3000GT was the original model, while the Dodge Stealth was a rebadged version sold through Dodge dealerships.
- Styling: The main difference is the exterior styling, with Chrysler designing the front of the Stealth to be distinct from the 3000GT. Other differences include some interior trim and badging (e.g., the Dodge Ram logo on the Stealth's airbag).
- Features: Some trim-specific features differed, such as the digital climate control and active aero system on some 3000GT models not being available on the comparable Stealth models.
- Production: The Stealth was sold from 1991 to 1996, while the 3000GT was sold from 1991 to 1999 in North America.
