Can a Hybrid Turbo Upgrade Deliver More Power to a Peugeot 308 GTi?

There’s a wave of curiosity and fascination sweeping across car enthusiasts worldwide about the potential of hybrid turbo upgrades. Can these marvels of modern engineering really deliver more power to cars? More specifically, can a hybrid turbo upgrade amplify the performance of a Peugeot 308 GTi? You’re about to find out.

Understanding the Peugeot 308 GTi

Before we dive into the matter at hand, let’s first understand the vehicle we’re targeting. The Peugeot 308 GTi is a formidable car, a symbol of French engineering prowess, and a competitor to the likes of the VW Golf GTI and BMW M135i.

Built with a 1.6 litre THP turbocharged engine outputting 270 bhp stock, it’s a hot hatch that can deliver thrilling performance. The power-to-weight ratio of the Peugeot 308 GTi is one of the best in the hot hatch segment, making it a sporty drive that’s hard to beat. However, can we make it even better with a hybrid turbo upgrade?

The Power of a Hybrid Turbo Upgrade

So, what exactly is a hybrid turbo? It’s a turbocharger that’s been modified or custom built to deliver more power than the original unit. By using the existing housing but replacing the internal components with larger, more efficient ones from bigger turbos, a hybrid turbo can push more air into the engine, resulting in increased power.

The potential gains from a hybrid turbo upgrade can be significant. Depending on the engine and turbo setup, power gains can range from 20 to 50 percent. For a car like the Peugeot 308 GTi, which already has a potent 1.6 litre turbocharged engine outputting 270 bhp, a hybrid turbo upgrade could potentially push power output to more than 320 bhp.

The Peugeot 308 GTi Hybrid Turbo Drive Review

Let’s imagine we’ve successfully installed a hybrid turbo in a Peugeot 308 GTi. What can we expect from this upgrade in real-world driving situations? The answer is quite simple: more power and improved performance.

A hybrid turbo will forge the Peugeot 308 GTi into a more potent machine capable of even better acceleration and top speed. The hybrid turbocharger can create more boost, which means more air into the engine, leading to more fuel being burnt and ultimately, more power being produced.

However, it’s crucial to remember that a hybrid turbo isn’t just about raw power. A well-built hybrid turbo will also improve drivability and throttle response, making the car feel more responsive to your inputs. In essence, the car will not only be faster, but it will also be more enjoyable to drive.

Integrating a Hybrid Turbo with the HDi Engine

One of the most common questions when considering a hybrid turbo upgrade for a Peugeot 308 GTi is how it will integrate with the HDi engine. HDi, which stands for High-pressure Direct Injection, is a type of fuel injection used by Peugeot. It’s known for its efficiency and clean performance.

With a hybrid turbo upgrade, the HDi engine of the Peugeot 308 GTi can be further optimized for performance. By forcing more air into the engine, the turbocharger can make the fuel burn more efficiently, resulting in more power.

In other words, a hybrid turbo can enhance the HDi engine’s performance while maintaining its efficiency and eco-friendliness. It’s a combination of power and responsibility that makes the hybrid turbo a worthwhile upgrade for the Peugeot 308 GTi.

Comparing the Peugeot 308 GTi to Other Cars

Now that we’ve seen what a hybrid turbo can do for a Peugeot 308 GTi, how does it stack up against other cars in the same segment? The Volkswagen Golf GTI and the BMW M135i, for example, are also popular choices for hot hatch enthusiasts.

The VW Golf GTI, with its 2.0 litre turbocharged engine producing 245 bhp, is a worthy adversary. However, with a hybrid turbo upgrade, the Peugeot 308 GTi could potentially outmatch the Golf GTI in terms of power.

The BMW M135i is a more challenging contender, with its 2.0 litre turbocharged engine pushing out a whopping 306 bhp. But even against this heavyweight, a hybrid turbocharged Peugeot 308 GTi could hold its own, providing an exhilarating driving experience that rivals its German counterpart.

In conclusion, a hybrid turbo upgrade can indeed deliver more power to a Peugeot 308 GTi. It can forge a more potent, responsive, and exciting driving machine, all while maintaining the efficiency and eco-friendliness of the HDi engine. It’s a combination that makes the Peugeot 308 GTi a hot hatch worth considering, even in a market filled with formidable competitors.

Turbo Upgrade Installation Process and Cost

To deliver more power to your Peugeot 308 GTi, you might be considering the addition of a hybrid turbo upgrade. The process of installing a hybrid turbo is quite technical and should ideally be done by a professional or someone with a strong understanding of the internal workings of a car engine. It involves replacing the stock turbocharger with a larger, more efficient one, installing a turbo blanket to prevent heat soak, and recalibrating the engine to accommodate the new turbo.

The cost of a hybrid turbo upgrade can vary significantly based on the specific model of turbo chosen and the labour involved in the installation process. A general ballpark figure is around $3000 to $5000. However, it’s worth noting that this investment can greatly enhance your car’s performance and driving pleasure.

Depending on the turbo upgrade, you may also need to install additional high-performance parts to support the increased power output. These might include an upgraded exhaust system, a higher-capacity intercooler to reduce intake temperatures, and enhanced brake systems to handle the increased speed and power.

Moreover, the Peugeot Sport division, renowned for developing high-performing racing versions of the Peugeot cars, will be an excellent resource for obtaining high-quality performance parts. Renowned companies like Forge Motorsport also provide a wide range of performance parts that you can select from their options.

Hybrid Turbo on the Peugeot RCZ and Future Developments

The hybrid turbo isn’t a novel concept for Peugeot. It has been successfully used in the Peugeot RCZ, a sports coupe that shares many similarities with the 308 GTi. With the hybrid turbo, the RCZ saw a significant increase in power, demonstrating the potential of this upgrade.

Looking ahead, the hybrid turbo seems poised to become an increasingly popular upgrade. With automakers and consumers alike becoming more conscious of environmental impact, the ability to enhance performance while maintaining efficiency is highly appealing.

The future might also see the development of even more advanced hybrid turbos, potentially incorporating electric assistance for even greater power and efficiency. Such electrically-assisted turbos could virtually eliminate turbo lag, providing instant response and power on demand.

In the news this Apr, Peugeot announced that they’re also considering hybrid technology for their next generation of hot hatches. With this development, we might see a factory-equipped hybrid turbo in the next Peugeot GTi model, which would indeed be a significant step forward in the hot hatch segment.


In the world of hot hatches, the Peugeot 308 GTi already stands out as a formidable contender. With the addition of a hybrid turbo upgrade, its performance can be further amplified, potentially pushing it to the top of its class. This upgrade not only delivers more power but also improves overall drivability and throttle response, making the GTi Peugeot an even more exciting car to drive.

The hybrid turbo’s ability to increase power while maintaining the HDi engine’s efficiency positions it as an attractive upgrade option. As a Peugeot GTi owner, this upgrade is undoubtedly worth considering, especially if you’re after more power, better performance, and an exhilarating driving experience that rivals top gear vehicles.

While the initial cost might seem steep, the benefits it delivers in terms of enhanced driveability and performance make the hybrid turbo a worthwhile investment.
