But what's the real deal with twin turbos on these awesome Japanese machines? Let's explore everything you need to know, from the basics to the nitty-gritty details. We're going to cover why you might want to consider this upgrade, what it involves, and some of the legendary Toyota models that can truly benefit from this forced induction boost. So buckle up, because we're about to get turbo crazy!
Why Go Twin Turbo on Your Toyota?
Okay, so why should you even consider slapping a twin turbo system onto your beloved Toyota? The answer, in short, is power. More specifically, we're talking about a significant increase in both horsepower and torque. A turbocharger works by forcing more air into the engine cylinders than the engine could naturally draw in on its own. This allows the engine to burn more fuel, resulting in a bigger, more powerful combustion. Now, imagine doing that twice over – that's the beauty of a twin-turbo setup! These systems provide a more efficient way to deliver that extra boost, often reducing what's known as "turbo lag." Turbo lag is that slight delay you sometimes feel when you stomp on the gas in a turbocharged car before the turbo spools up and delivers the power. Twin turbos, especially when configured as sequential turbos, can mitigate this lag by using a smaller turbo at lower engine speeds for quicker response and then bringing in a larger turbo at higher speeds for maximum power. Think of it as having the best of both worlds: snappy acceleration off the line and relentless pull as you climb through the rev range.
Beyond just raw power, a twin turbo setup can also improve the overall driving experience. The increased torque means you'll have more pulling power at lower RPMs, making your Toyota feel more responsive and eager to accelerate in any situation. Whether you're merging onto the highway, climbing a steep hill, or just want to have some fun on a twisty road, the extra power from a twin-turbo system is always there when you need it. Plus, let's be honest, there's something undeniably cool about the sound of a turbocharged engine, and with two turbos working in harmony, that sound is only amplified. The distinctive whistle and whoosh of a twin-turbo Toyota are sure to turn heads wherever you go. However, it's crucial to remember that adding a twin-turbo system is a significant modification that requires careful planning and execution. It's not just a bolt-on affair; it often involves upgrading other components of the engine and drivetrain to handle the increased power output. We'll delve into those considerations later on, but for now, just keep in mind that a twin-turbo upgrade is a serious commitment that should be approached with knowledge and a healthy dose of respect.
Legendary Toyota Models Ripe for a Twin Turbo Upgrade
Now that we've established why a twin turbo setup is so desirable, let's talk about some iconic Toyota models that are particularly well-suited for this type of upgrade. The Toyota Supra is perhaps the most obvious choice. The fourth-generation Supra, with its legendary 2JZ-GTE engine, came from the factory with a twin turbo configuration. However, even these engines can be upgraded with larger, more efficient turbos to unlock even greater power potential. The aftermarket support for the Supra and its 2JZ engine is vast, making it relatively easy to find high-quality turbo kits and supporting components. Whether you're looking to build a street-legal monster or a dedicated track weapon, the Supra is an excellent platform for a twin-turbo build.
Another Toyota that's a prime candidate for a twin turbo conversion is the Toyota MR2. While the MR2 never came from the factory with a twin-turbo engine, its lightweight chassis and mid-engine layout make it a fantastic platform for forced induction. Several aftermarket companies offer twin-turbo kits specifically designed for the MR2, and with the right modifications, these cars can become incredibly quick and nimble. Imagine the thrill of piloting a mid-engine sports car with the explosive power of a twin-turbocharged engine – it's a recipe for driving nirvana! Then there's the Toyota Aristo, a luxury sedan that shares its engine with the Supra. Although not as widely known as the Supra, the Aristo is a comfortable and capable platform that can be easily transformed into a high-performance sleeper with a twin turbo upgrade. Its luxurious interior and understated styling make it the perfect car for those who want to fly under the radar while still packing a serious punch. Of course, these are just a few examples, and with enough ingenuity and resources, you could potentially add a twin-turbo system to almost any Toyota model. However, these three cars represent some of the most popular and well-supported platforms for twin-turbo conversions.
Key Components and Considerations
So, you're serious about adding a twin turbo system to your Toyota? Awesome! But before you start ordering parts, let's talk about some of the key components and considerations involved in this type of project. First and foremost, you'll need a twin turbo kit. These kits typically include the turbochargers themselves, along with all the necessary piping, manifolds, and mounting hardware. When choosing a kit, it's important to select one that's specifically designed for your engine and that's made from high-quality materials. A cheap or poorly designed kit can lead to problems down the road, so it's worth investing in a reputable brand. In addition to the twin turbo kit, you'll also need to upgrade your engine's fuel system. The increased air volume from the turbos will require more fuel, so you'll likely need to install larger fuel injectors, a higher-flowing fuel pump, and possibly even an aftermarket fuel rail. Failing to upgrade the fuel system can result in a lean condition, which can damage your engine.
Another crucial consideration is engine management. The factory ECU (Engine Control Unit) is unlikely to be able to properly control a twin turbo engine, so you'll need to either reprogram the existing ECU or install a standalone engine management system. A standalone ECU offers the most flexibility and control, allowing you to fine-tune the engine's parameters for optimal performance. However, it also requires more expertise to set up and tune properly. You'll also need to upgrade your car's cooling system. The increased power output from a twin turbo engine will generate more heat, so you'll need to install a larger radiator, a more efficient intercooler, and possibly even an oil cooler. Overheating can quickly lead to engine damage, so it's essential to keep your engine running cool. Finally, don't forget about the drivetrain. The stock transmission, differential, and axles may not be able to handle the increased torque from a twin-turbo engine, so you may need to upgrade these components as well. A stronger transmission, a limited-slip differential, and heavy-duty axles will help ensure that your car can reliably put the power down to the ground. This is why a twin turbo project is not cheap and you need to research well what you are going to do.
Installation and Tuning: Getting it Right
Once you've gathered all the necessary components, it's time to start the installation process. Unless you're a highly experienced mechanic, it's generally recommended to have a professional install your twin turbo system. The installation process can be complex and time-consuming, and it's easy to make mistakes that can damage your engine. A professional installer will have the knowledge and experience to ensure that everything is installed correctly and that your engine is running properly. After the installation is complete, the next step is tuning. Tuning involves adjusting the engine's parameters, such as fuel delivery, ignition timing, and boost pressure, to optimize performance and ensure that the engine is running safely. Tuning should be done by a qualified tuner with experience in twin turbo engines. A good tuner will be able to extract the maximum power from your engine while keeping it within safe operating limits.
The tuning process typically involves using a dyno, which is a machine that measures the engine's horsepower and torque output. The tuner will make adjustments to the engine's parameters while monitoring the dyno readings to see how the changes affect performance. The goal is to find the optimal settings that provide the most power without causing any damage to the engine. Tuning can take several hours or even days to complete, depending on the complexity of the engine and the desired level of performance. It's important to be patient and allow the tuner to do their job properly. A poorly tuned engine can be just as damaging as a poorly installed one, so it's worth investing the time and money to have it done right. Always remember, safety first! Working with turbochargers and high-performance engines can be dangerous if you don't know what you're doing. If you're not comfortable with any aspect of the installation or tuning process, it's best to leave it to the professionals. A mistake can be costly and even dangerous, so it's always better to err on the side of caution. Enjoy the process and prepare to be amazed by the transformation of your Toyota into a twin turbo beast!
