Single Turbo
In the case of a single turbo, you will find this to be smaller and more cost-effective than the twin. The power band is greater, which means you can expect more horsepower and it builds boost slower, too. Thus, if you want to maximize your car’s performance, it is worth looking into a single turbo for it. Moreover, it works well when there is not much space available under the hood since it is more compact.
Twin Turbo
On the other hand, a twin turbo means it is bulkier. This is why you would need to have more space for this turbo in your engine. If you are using your vehicle on a daily basis, then a twin turbo should be practical as it needs exhaust from all four cylinders, making it run faster. Hence, if you want to prevent any turbo lag, then a twin turbo is a suitable choice for you.
When it comes to choosing between the two types of turbo, you should determine how your decision can impact the vehicle. You need to weigh your options whether you have a performance vehicle, everyday car, or if you are even ready to deal with practical issues such as space, which is a requirement for a twin turbo.
In the case of a single turbo, the expected gain is at 1.5 MPG – and this also helps to prolong the lifespan of your engine, providing more power and less maintenance needs. This is why there are those who choose to convert to a single turbo because of these benefits.

- Increased reliability
- Longer engine life
- Improved fuel economy
- Less maintenance needs

Converting to a single turbo offers simplicity since you only have to deal with one turbo instead of two, which can often be messy once problems arise.

But the cost should be less than what you need for a twin turbo. Plus, it is easy to obtain single turbos instead of the twin. This means you can choose from a number of brand and size options for your turbos that are compatible with your vehicle.
When you have a single turbo, there is an unlimited amount of turbo choices and exhaust housing. The compressor wheel size is also numerous, and you can use this to support a power level needed by your engine.

Ths, you need to really make sure that this is done well, otherwise, there may be a persistent heat problem, which can impact the performance of your vehicle.
