Which Engines Are Compatible with the 2007 Hyundai Tiburon 2.7L V6?
The 2007 Hyundai Tiburon, especially the version equipped with the 2.7L V6 engine, was one of Hyundai’s bold attempts to compete in the affordable sports coupe market. This V6-powered model offered a solid blend of performance, style, and reliability, which has made it a popular choice among budget-minded car enthusiasts and tuners. If you own one or are thinking about modifying or replacing the engine, you might be wondering: what engines are actually compatible with the 2007 Hyundai Tiburon 2.7L V6?
Let’s break down the most compatible engine options—from direct replacements to potential swap candidates—and what you need to consider before doing a swap.
Direct Replacement: Hyundai 2.7L Delta V6 (G6BA)
The simplest and most straightforward option is to replace the original engine with another of the same kind. The Hyundai 2.7L Delta V6 (engine code: G6BA) is what came stock in the 2007 Tiburon GT. If your current engine is failing or has high mileage, this is your best plug-and-play option.
The G6BA engine was used in a range of Hyundai and Kia models, including:
- 2003–2008 Hyundai Tiburon GT
- 2001–2006 Hyundai Santa Fe
- 2001–2006 Hyundai Sonata
- 2001–2005 Kia Optima
- 2002–2005 Kia Magentis
- 2003–2006 Kia Sorento (in some markets)
These engines share similar block dimensions and mounting points, making them highly compatible. However, keep in mind that even within the same engine family, some sensors, intake manifolds, or ECU parameters might differ slightly, depending on the donor vehicle. It’s always a good idea to use the ECU and wiring harness that matches your Tiburon if you’re doing a straight swap.
Compatible Engine Swaps Within Hyundai/Kia Family
If you’re looking to upgrade or simply swap to a different engine within the Hyundai/Kia family, you have a few more options—though none are direct bolt-ins and all require some degree of modification.
1. Hyundai 3.5L V6 (G6CU or G6DB – Sigma Engine Family)
Some enthusiasts have explored the possibility of swapping in the 3.5L V6 used in the Hyundai Santa Fe, XG350, and Kia Sorento. These Sigma V6 engines share some basic architecture with the Delta 2.7L, but they are physically larger and often require custom mounts, transmission modifications, and ECU tuning.
Pros:
- Increased displacement and power
- Still within the Hyundai engine family
Cons:
- More complex swap
- Custom wiring and ECU management needed

2. 2.0L Turbocharged (Theta II G4KF from Genesis Coupe)
A more ambitious and performance-oriented swap would be the Theta II 2.0T engine from the Genesis Coupe. It’s lighter than the V6 and can produce more horsepower with tuning.
This trade isn’t for the weak of heart, though. You’ll need:
- Custom engine mounts
- Full ECU and harness conversion
- Possibly a new transmission and drivetrain adjustments
Non-Hyundai Engine Swaps (Highly Custom)
Some builders have managed to fit completely unrelated engines, such as the Honda J-series V6, Toyota 1UZ-FE, or even LS V8 engines into the Tiburon chassis. These swaps are incredibly complex and require:
- Fabricating custom mounts
- Rewiring the vehicle entirely
- Upgrading the drivetrain, suspension, and often the brakes
- Deep pockets and a lot of patience
Unless you’re building a show or race car and have a solid budget, these options are generally not recommended for average DIYers.
Important Considerations Before an Engine Swap
Before you decide on a compatible engine swap or replacement, here are a few key things to consider:
- Budget: A direct replacement can cost between $1,000 and $3,000. Engine swaps can easily exceed $5,000–$10,000 with labor.
- Skill Level: Are you doing it yourself or hiring a shop?
- Emissions Laws: Some states require the replacement engine to be from the same year or newer, and emissions compliant.
- Transmission Compatibility: Will your current transmission mate with the new engine?
- ECU and Wiring: Most swaps will require some level of reprogramming or a standalone ECU.
Final Thoughts
If your goal is to keep your 2007 Hyundai Tiburon running smoothly without much hassle, sticking with the original 2.7L G6BA V6 engine is your best bet. It’s relatively easy to find and compatible with your existing drivetrain and electronics. For those looking for more performance or a unique project, there are a few engine swap options out there—but be prepared for fabrication, wiring, and tuning challenges.
Whether you’re restoring a daily driver or building a track toy, knowing your engine compatibility options will help ensure a smoother, more successful build.
