A rev-happy engine, roaring inline-4 cylinder, and a redline at 9000 rpm. What more could you want from your Honda S2000?
If your answer is more power, then you’re reading the right guide.
Once you get a taste of Honda’s legendary VTEC, you’re only going to want more. It’s a tonne of fun to drive anywhere from the race track to twisty mountain roads and even around your neighborhood.
So we’re pretty sure that supercharging your roadster must have crossed your mind by now. And as the Honda S2000 celebrates its 20th anniversary, what better time to amp up the power?
Fasten your seatbelts as we take you through the best supercharger kits for the Honda S2000, as well as everything you need to know before you get started.
But first, let’s get familiar with the very principle that’s going to speed up your S2000— forced induction.
How Forced Induction Works
With great power comes a great need for more air.
Your car’s ability to produce more power depends on how much fuel it burns and how fast it can convert this heat to mechanical force. And to burn more fuel, you’re obviously going to need more air.
That’s where forced induction comes in. As the name suggests, you’re literally force-feeding your internal combustion engine more air than it would normally ingest. It’s a sure-fire way to instantly produce enough power to get the speed junky in you very excited.
Forced induction can be achieved with the help of both turbochargers and superchargers which are essentially air compressors. What sets them apart is their efficiency, performance and most importantly— how they deliver power.
S2000 Supercharger Vs Turbocharger: Which Suits the Honda Better?
Turbochargers and superchargers both help you significantly increase your car’s horsepower, it’s just that they do it differently.
Turbochargers use your car’s exhaust to spool up a turbine, which powers a compressor that draws air into your engine. And since it’s turning your exhaust gas into something useful, turbochargers are definitely more efficient — at least in theory.
A supercharger, on the other hand, is connected directly to your engine’s crankshaft in order to generate power. It can either be belt-driven or gear-driven but either way, it’s the engine that’s powering it.
The Clear Winner for the Honda S2000
Given the linear power band and the fact that they retain the same “stock-like” feel of the F20C and F22C, superchargers are a favorite amongst Honda S2000 owners.
Superchargers are also less stressful on your engine and drivetrain. They’re more reliable, easier to install and have lower maintenance requirements as well.
Of course, they do make less total power than a turbo but you won’t have any lag in power delivery. The boost is instantaneous since the supercharger is directly connected to your engine.
Also, let’s not forget how great superchargers sound on a Honda F20C or F22C!
Types of Superchargers
Now that we agree about how awesome superchargers are going to make your Honda S2000, let’s get a little familiar with the different kinds.
While they all do the same thing, some are more efficient than others. Especially when it comes to torque delivery.
First up, we have the Roots supercharger systems which are the oldest of the lot. They’re usually pretty big and sit nice and snug on top of the engine. But when it comes to efficiency they’re not a popular pick.
This is simply because they’re too heavy and are going to end up adding a lot of unnecessary weight to your lightweight S2K. Another negative is that their power output isn’t linear and smooth but rather sporadic and in choppy bursts.
This gives you a sudden surge in power which is not always predictable and affects comfort for street use.
Slightly more efficient than the Roots supercharger, the twin-screw system pulls in air through a pair of meshing lobes which fit together like gears. The air is then trapped inside tiny pockets within the housing and even compressed there because of the rotor design.
A twin-supercharger creates more noise than the Roots supercharger which resembles a whine or a whistle. Some people love it, others hate it.
Our favorite of them all? You guessed it!
Centrifugal superchargers are the most common of the three and are way more efficient than its counterparts. They resemble a turbocharger in some ways too.
They boast of a powerful setup consisting of an impeller which works similar to a rotor. This impeller draws in air at high speeds and can reach a staggering 50,000 rpm.
Centrifugal superchargers are better at dealing with heat levels than other superchargers. More than anything else, what really makes them a popular choice is the smooth and consistent torque delivery.
Another important piece of information is that an engine equipped with a centrifugal supercharger will make the most power at its highest rpm. And given the high rev range from your Honda S2000’s F20C or F22C, the two fit together rather well.
Do Honda F20C and F22C Supercharger Builds Need Forged Internals?
The more power you add to your car, the more stress it will put on your engine and other parts.
Luckily your Honda S2000 can handle it. Apart from it’s strong build, it has forged internals that allows you to considerably increase power without needing any internal engine modifications.
In fact, your stock motor is much stronger than any other OEM Honda out there so it would be a shame not to supercharge it.
Both the F20C and F22C engines can safely handle 400 whp on stock internals with some high quality spark plugs and performance motor oil. To gain anything more than that, we recommend upgrading your engine components.
Recommended Supporting Modifications
Before getting your hands on any of the superchargers on our list, there are a couple of supporting mods that you should consider making to your S2K.
With any kind of forced induction system, the first thing you need is a clutch upgrade. An uprated pressure plate and clutch disc will help your S2000 to get the power to the wheels by keeping the clutch from slipping when you are really putting your car under heavy load.
While the OEM headers and exhaust may serve you well, we recommend at least upgrading to a test pipe or high flow catalytic converter for your S2000 supercharger setup. For more info, read our guide to the best S2000 exhausts.
A few other supporting mods to consider are:
- Fuel injectors, fuel pump and rails
- Upgraded engine management
- Performance S2000 spark plugs
- Intercooler and piping
Are S2000 Supercharger Installs Difficult?
The way a supercharger fits on your S2000 depends on the type of blower kit you buy. Most kits bolt on easily while others are a little more complicated.
In comparison to turbochargers, they’re easier to install. But while you may be tempted to get your hands dirty, it’s best to leave the installation to the pros unless you really know what you’re doing.
Most of the top supercharger kits for the S2000 are equipped with a centrifugal setup which is slightly more complicated to install than the Roots setup.
For the best results, make sure your car has been dyno’d or at least street tuned after the installation.
How Much Should I Budget for an S2K Supercharger?
Any form of forced induction is by no means a cheap S2000 performance upgrade. There’s a lot more to it than simply purchasing and installing a supercharger kit on your S2K.
When you’re budgeting for this upgrade, we recommend that you take into account all the other expenses that come with it. Some of them include:
- Labor cost for installation
- Shipping cost for the kit (if applicable)
- Supporting upgrades
That said, it’s best to expect a total cost of $10,000 to $15,000.
