Budget is, let's face it, one of the most important things to consider! Engine swaps and turbocharging projects can quickly become expensive, so it's vital to set a realistic budget from the start. B-series engines are often the most affordable option, as they are older and more readily available. K-series engines tend to be more expensive, especially the sought-after K20A variants. The F-series engines, particularly the F20C from the S2000, can also command a premium due to the car's desirability. Besides the engine itself, you'll need to factor in the cost of the turbocharger kit, fuel system upgrades, engine management, and, of course, the labor for installation and tuning. Also, the availability of parts is also important. Some engines are easier to find parts for than others. The B series engines are easily available, and if you are on a budget these engines are your best bet.

Your Power Goals: What Are You Aiming For?

How much power do you actually want? The answer will heavily influence your engine choice. If you're looking for a moderate power increase (300-400 horsepower), a well-built B-series engine or a lightly modified K-series engine might be sufficient. If you're aiming for extreme power levels (500+ horsepower), you'll likely need a K-series engine with upgraded internals or an extensively built F-series. It's crucial to be realistic about your goals and choose an engine that can reliably deliver the power you crave. Remember, guys, chasing huge horsepower numbers often requires significant investment and compromises in terms of reliability and drivability. The power you choose should align with your end-use case. If you intend to use the car for daily driving, then a high-powered engine might not be the best solution. However, if the car is primarily used for the track, then a high-powered engine is the best solution.

Reliability: Long-Term Durability

Reliability is paramount, especially if this is your daily driver. While all the engines we've discussed can handle boost, some are inherently more robust than others. The B-series engines, with their forged internals in some variants, are known for their durability. The K-series engines, thanks to their modern design and strong bottom ends, are also generally reliable when properly built. It's vital to choose an engine that can withstand the added stress of turbocharging and to invest in high-quality components and proper tuning. If you plan to push your engine to its limits, consider upgrading the internals (pistons, rods, etc.) to ensure longevity. Also, reliability greatly depends on your tuning and how well you maintain your car. So it is important to choose a skilled tuner to get the most out of your engine.

The Aftermarket: Parts and Support

The availability of aftermarket parts and support is another important consideration. Both the B and K-series engines have massive aftermarket followings, meaning you'll have no trouble finding turbo kits, engine components, and expert advice. The F-series engine has a more niche market, but there are still plenty of options available, especially for the S2000.

Turbocharger System: The Heart of the Beast

The turbocharger itself is the star of the show! Selecting the right turbocharger is crucial for achieving your desired power goals and responsiveness. Consider factors like the turbo's size (which affects its power band), the type of bearings (ball bearing turbos offer better spool), and the overall quality. Reputable brands like Garrett, Precision Turbo, and BorgWarner offer a wide range of turbos to suit various power levels. The turbo is going to be one of the most important components in your turbo setup. So it is important to do your research on which turbo is the best for your application. Also, your turbocharger choice will be determined by your budget. The bigger and better the turbocharger, the more money it will cost.

Fuel System Upgrades: Feeding the Monster

Boosting an engine demands more fuel. You'll need to upgrade your fuel injectors, fuel pump, and potentially your fuel rail to provide the engine with the necessary fuel supply. Insufficient fuel can lead to catastrophic engine damage. Make sure the injectors and fuel pump are properly sized for your target horsepower. Also, when upgrading your fuel system, you should consider the use of an aftermarket ECU to make the process easier. The fuel system is what supplies fuel to the engine. If the engine does not have enough fuel, then the engine will not produce power. So it is important to ensure that you have a proper fuel system.

Engine Management: The Brains of the Operation

You'll need a way to control the engine's functions under boost. This typically involves an aftermarket engine control unit (ECU). The ECU will allow you to adjust fuel maps, ignition timing, and other parameters to optimize the engine's performance and ensure its safety. Popular ECU options include Hondata, AEM, and Haltech. Tuning is critical for a boosted engine, so invest in a reputable tuner with experience in Hondas. The aftermarket ECU is the brain of the operation. Without a proper ECU, then your engine will not run well. A proper ECU will ensure that your engine runs smoothly and reliably.
