Now and then, we’re feeling nice, and we decide to give the Honda fanboys some lovin’.

In this guide, we’ll be going through the best (and worst) turbo kits available for K24 owners and providing our recommendations on what’s likely to be the perfect setup for your requirements.

With their impressive reliability and power potential, the K-series engines have proven an ideal choice for both FWD and RWD builds.

We recently took an in-depth look into the selection of Honda’s most popular engines frequently used for RWD swaps, such as the K20, K24, and the B16.

As unlikely as it may seem, Honda’s K24 has repeatedly proven to be a solid choice for a wide variety of RWD builds in just about every motorsport discipline.

While the K24 might not be the logical choice for an RWD build, given their FWD nature, we feel that they can be an immensely underrated engine swap if you’re willing to put in the effort.

Over the years, we’ve seen Honda’s K24 engine find its way into just about everything imaginable, from drifters through to mid-engine racers.

While the likes of V8 swaps have become the go-to choice in motorsport and games such as Madalin Stunt Cars 3, this has left the prices heading sky-high, where other options, such as the K24, can be found for just a few hundred bucks.

Sure, the likes of GM’s LS engine offer impressive reliability and power potential and can also handle forced induction efficiently.

But, the Honda K24 also ticks all of these boxes at a fraction of the initial cost.

If you’re curious to see how the K24 fares against the LS, check out this great video from Speed Academy:

A wide range of K24 engines can be found in some of the most popular cars on the market, such as Honda Accord’s and CR-Vs, making them highly convenient and cheap to source.

They’re also an ideal choice when it comes to off-the-shelf upgrades and aftermarket support.

With an ever-increasing off-the-shelf aftermarket mounting and wiring options available for the K-series, it’s undoubtedly emerging as an underdog in the engine-swap world.

So, whether you’re looking for a cheap and reliable drift car engine swap or a fully-boosted setup that’ll be able to help you smash ¼ mile records, the K24 should undoubtedly be a contender to consider.

After its initial launch in 2001, the K24 powerplant debuted in the Honda CR-V with the original K24A1 variation.

Although Honda continues production today with the K24Y and K24Z variants, these modern-day versions aren’t going to be ideal candidates for a turbo swap.

The K24’s design is remarkably similar to its predecessor, the 2-liter K20, featuring some additional bonuses alongside the more significant displacement, such as an enlarged bore and stroke, friction-reducing technology, and electronically controlled ignition timing.

Honda K24 N/A Tuning Potential

There’s a great selection of off-the-shelf products when it comes to upgrading the K24 engine, and some incredible power figures lie in wait if you’re willing to put the time and money into unleashing its potential.

The highest output in stock form comes from the sought-after K24A2, which produces 205 hp and 164 ft/lb torque out of the factory with the Acura TSX, but what if we want to aim higher?

Generally, the recommendation to get the best basic setup with the K24 is to buy any K24A cylinder block, along with a K20A2, K20A Euro R, or KA20A Type R head, commonly known as the “K20/K24 Frankenstein”.

Remember that this only applies to the K24A series engines. The K24Z isn’t compatible due to the pistons making contact with the K20’s cylinder head.

Although it may seem odd to use K20 parts, the K20 features superior valve springs and camshafts to the K24. If you decide to opt for this route, you’ll also want to consider replacing the K24’s water pump with the K20’s.

If you go the whole way, with race bearings, high-compression pistons, rods, studs, an uprated flywheel, fuel injectors, an ECU upgrade, and a K20A2 oil pump, you’re likely to get about 260 horsepower.

Suppose that’s not enough, and you’re keen to reach 300hp without looking at the forced induction route; it’s achievable with a little more work.

Reaching the 300 hp mark would require additional internal porting, uprated valves, cams, throttle body, a CAI, and uprated manifolds with a high-flowing exhaust setup.

For the finest N/A K24’s available, you can consider turn-key crate engines, capable of 340 hp at 9,000 rpm, through to drag racing setups capable of under 9-second quarter-mile times.

Honda K24 Forced Induction

Since the K24 can handle forced induction well, it’ll come as no surprise that many owners opt to go down the turbocharged route with their build.

If you intend to go beyond 400 hp, then a turbo kit will likely provide the best option for the money.

Thankfully, the K24 is one of the most convenient engines for forced induction and can often be one of the cheapest and most convenient engines to modify.

With the stock internals capable of handling up to 4-500hp, it’s easy to see why so many people opt for the K24 when it comes to engine swaps.

There’s certainly no shortage of turbocharged K24’s out there, but there’s also a decent amount of supercharged ones, too.

Deciding which forced-induction route you want to take isn’t always easy, so we highly recommend checking out our turbocharger vs supercharger guide before you commit to your choice.

Once you’ve decided that the turbo kit will be best for your needs, it’s time to choose from the best options on the market.

The K-series engine is capable of some impressive figures, and some enthusiasts have achieved over 500hp from the stock block.

Although this is the case, you’ll need to consider swapping out several parts when hunting down significant power.

With considerations such as an uprated/aftermarket transmission, there are chances that your ride will no longer make for an enjoyable, reliable, daily driver.

Traction will also be a serious consideration when it comes to putting significant power down, especially if you’re opting for a turbo kit on your FWD car.

Many of the K24 turbo kit information online is now outdated, and many of the options are no longer in production, so we’ll help you explore the best choices currently available.

You’re most likely aware that turbo upgrades are no joke, and with an incorrect setup, you’ll soon need to start planning the inevitable funeral for your currently healthy engine.

Sure, custom builds can sometimes be the way forward, but unless you’re a skilled mechanic, then an off-the-shelf kit is likely to save you a lot of hassle along the way.

Whether you’re looking for the ultimate K24 setup or a simple budget build that can be put together over a few beers on the weekend with the homies, we’ll cover them all in this guide.

For that reason, we always recommend that you decide what your end goal is likely to be when choosing the best turbo kit for your specific needs.

Are you merely wanting some sensible additional power on your daily? Or are your plans to build a dedicated track weapon that will require a trailer to take to events?

Forced induction does, of course, put a lot of strain on any engine, especially older ones that have perhaps not been fantastically well-cared-for.

As always, we highly recommend ensuring that the base engine that you intend to turbocharge is running healthily, and the best way to do this is with a compression test.

It’s also worth considering going with uprated internals to save the inevitable tears once you’ve started bouncing off the limiter later on, especially for big-power builds.

Once that all checks out, let’s move on and decide which turbo kit will be best suited for your goals!

Our comment: Among some enthusiasts, CXRacing has earned themselves a negative reputation, but they’ve completely redesigned their products in recent years, making them impressive quality for the price.

They offer three options with their kit, one which comes without an intercooler, and two that include the intercooler kit in with the package, with a choice of blue or black silicone hoses.

Although this won’t be as impressive as the Humble Performance kit above, it provides excellent value for money, coming in at a fraction of the price.

Our comment: If the 600 hp kit from Humble Performance wasn’t enough for your needs, how does potentially achieving double that with 1,200 hp sound?

That’s right, this insane kit from Full-Race comes at a price, but the incredible quality and fitment justify this that they provide.

Full-Race manifolds use robotically TIG welded runners for the ultimate strength and precision, ensuring the best durability possible.

While the ProStreet kit provides an ultra-responsive 300 whp setup, the Twin Scroll setup is the ultimate choice for those of you hunting down massive power goals.

Our comment: RXRacing offers two options in their K24 turbo kit lineup, with the 485 hp “Street Demon” kit providing an incredibly comprehensive package of everything you could need for your turbo build.

If you’re looking for a simple manifold, wastegate, and turbo kit setup to go with your DIY project, then the cheaper option of the two may be worth considering.

It’s the 485 hp package that caught our eye here, though. Although it’s somewhat of a “Chinese” turbo kit, there’s no questioning that you get a lot for your money here.

While the quality won’t be up to the standard of the rest of the choices in this guide, it provides a budget alternative and may well provide an ideal solution if you’re stuck on your custom build and require some specific parts.

Since it comes with a universal intercooler piping kit, this will require some custom work to ensure the perfect fitment.
