For usage in the Honda S2000, Honda created the F20C and F22C1 inline-4 engines. They are one of the few Honda 4-cylinder car engines with a longitudinal seating arrangement for rear-wheel drive.
These engines are not closely related to the F-series engines used in the Honda Accord and Prelude in the mid-1990s.
[1] Honda engineers used technologies from Honda’s racing engines to make the most of the little engine.
The F20C and F22C1 both use a timing chain and have two overhead cams with roller followers, a ladder-frame main bearing stiffener, a VTEC system for both the intake and exhaust camshafts, Fiber-Reinforced Metal (FRM) cylinder liners, and molybdenum disulfide-coated piston skirts for reduced friction.
There are two distinct cam lobe profiles used in the VTEC system. The cam phasing is not variable. In order to reduce friction in the valvetrain, roller followers are used. Metal injection molding is used to build the rocker arms.
The aluminum engine block has a metal sleeve with fiber reinforcement. The cams are driven by an intermediate gear, which is driven by a timing chain. They are aluminum forged pistons. For quick engine response, the intake plenum was designed with a small volume, and until 2004, a 14 lb (6.4 kg) flywheel was included. The combination of a high-flow catalyst and an exhaust air-injection system significantly reduces the catalyst’s light-off time and cold emissions.

Which Honda models have K24 engines?
The K24A-branded K24 engines weren’t offered for sale in the domestic market. These engines, which came in two major types, were mostly found on JDM products. There was a sportier variant with a compression ratio of either 10.5:1 or 11:1, and there was a less potent version that was more focused on the economy. The sportier of the two is better recognized because it had a stock power output of about 200 horsepower.
The 2002–2008 Honda Accord Type-S (JDM) and the 2003–2008 Honda Odyssey Absolute both had this more powerful K24A engine. While it produced a somewhat lesser 197 hp in the Odyssey, it produced a remarkable 205 hp and 171 lb-ft of torque in the former. Meanwhile, torque remained constant.
Honda K24A2
One of the best four-cylinder engine ready-to-run models is thought to be the K24A2. However, the publicity surrounding it has also raised the cost of the engine, making it less economical than a slightly modified variation of the less well-liked K-series engines.
The only significant differences between the K24A2 and the aforementioned K24A are a changed water pump housing, a sensor on the VTEC solenoid, and a few other minor details. K24A2, which was standard on the Acura TSX from 2004 to 2008, is widely available in the United States while K24A must be imported. This version, as opposed to the K24A1, has more sporty features such lighter pistons, a forged, fully counterweighted crankshaft, and a higher compression ratio similar to the JDM K24A.
The TSX’s 2004 and 2005 K24A2 engine produced 197 horsepower and 166 lb-ft of torque. A wider air intake, from 70 mm to 80 mm, a reworked throttle body, from 60 mm to 64 mm, as well as improved intake valves, a new intake camshaft, and an exhaust improvement, were added to the engine for the 2006–2008 model years. This resulted in an increase in power to 205 hp but a little decrease in torque to 164 lb-ft.
Is the engine in every S2000 the same?
The day the renowned Japanese company unveiled the Honda S2000, it instantly became a classic. It was first made available for the 1999 model year, and since then, it has consistently topped rankings of the best affordable sports cars. It handles like a go-kart and is compact, agile, and quick.
The Honda S2000 is one of the most entertaining vehicles you can buy, pound for pound. Undoubtedly, the engine of these cars is a key component of their pleasure.
At the Tokyo Motor Show in 1995, Honda unveiled plans to build a new sports car using a strong “x-bone frame technology. The S2000’s name comes from the engine’s original displacement, an inline four-cylinder 2.0-liter (2,000 cc) engine. The S moniker originated with the renowned Honda sports vehicles of the 1960s.
The engine displacement of the S500, S600, and S800 is likewise reflected in their names. Honda made the decision to revive the memorable name convention when creating the S2000.
There are two distinct generations of the S2000, known as AP1 and AP2. The 2.2-liter second-generation engine’s displacement was increased, but the S2000 moniker remained the same. From 1999 to 2003, the AP1 S2000 was in use, then from 2004 to 2009, the AP2 S2000. Each generation of the S2000 has slightly varying power outputs, fuel efficiency, and engine specifications despite the engines being quite comparable.
It’s crucial to know which generation and the specifics of each Honda S2000 you want if you’re on the market for one.
As always, you want to be as informed as possible while looking for a secondhand car. Let’s look at the engine specifications for both S2000 versions.
The Honda S2000 has VTEC, right?
It has a front engine, rear-wheel drive design, with a 1,997 cc (122 cu in) inline four-cylinder DOHC-VTEC engine that provides power.
What makes the S2000 unique?
First of all, that engine contributed to the mythology of the S2000. When you first start the car, this might not seem to be the case because it doesn’t seem to show anything exceptional as you wait for it to reach idle. You continue to apply some revs while pondering the fuss. However, the S2000 really starts to become truly unique until you find that redline and begin to drive it seriously. The S2000 had a normally aspirated production automobile engine with the highest specific output ever recorded. Remember that the engine produces 124 horsepower per liter—without a turbocharger or supercharging.
The engine is connected to the absolutely stunning manual transmission. For years, people have waxed poetic about this gearbox, but the truth is that it is just that amazing. According to publications like Top Gear, the mechanical connection you feel between the engine and the gears may perhaps be the greatest available right now. In the S2000, changing gear is an event rather than just a procedure. At high rpm, you can shift into the next gear quickly, or when softly cruising, you can shift into the next gear gradually. Honda did a fantastic job pairing the engine and transmission.
Honda S2000s are quick.
What Speed Is an S2000? The S2000’s 1,997cc inline four cylinder DOHC-VTEC engine produces 237247hp (depending on the market), allowing it to reach 100 km/h in about 6 seconds and reach a top speed of little over 255 km/h (158 mph).
VTEC is there in K24?
The K24Z3 engine, which debuted with the significantly heavier second-generation Acura TSX, underwent a considerable makeover once more.
The K24Z3 for the Honda Accord was essentially a K24Z3 with a high-flow exhaust system, capable of 190 hp and 162 lb/ft torque, despite having a 10.7:1 compression ratio and producing less power and torque.
The 2009–2014 Acura TSX K24Z3, on the other hand, has an updated engine with 31mm exhaust valves and a redesigned i–VTEC system, as well as a compression ratio of 11.0:1, which increased the vehicle’s output to 201 horsepower and 172 lb/ft of torque.
But it also had the better engine, which was the same as the K24Z7, for the CP2 and CS1 Honda Accord models.
Chain-driven dual balance shafts, i-VTEC on the intake and exhaust camshafts, lightweight pistons, upgraded rods, and computer-programmed fuel injection are all included in the K24Z3 (PGM-FI).
Can a K24 be turboed?
It should come as no surprise that many owners choose to take the turbocharged path with their build as the K24 can handle forced induction well. A turbo kit is probably the greatest value if you want to make more than 400 horsepower.
Which S2000 year is the best?
What years are ideal for purchasing? Truth be said, there is no undisputed “best year S2000. On paper, the 2002 and later versions should be chosen because they have updated suspension and glass back windows.
Honda S2000s uncommon?
Honda sold only 700 S2000 CR models, making them exceedingly rare. Due to their scarcity and assortment of track-focused improvements, they have increased in value over the past five years from being $30,000 cars to six-figure collectors. In addition to having unique wheels, a quicker steering rack, stiffer suspension, revised aero, extra chassis bracing, and a one-piece detachable hardtop roof, CR models also received these upgrades.
This one, which has 123 kilometers on the odometer and is finished in yellow over black Alcantara and cloth, looks the part. The interior is in excellent condition, and the body panels and roof piece appear to be in flawless condition. The car’s engine compartment and underside appear to have never been touched by the outside world, which is not unexpected given that it has only traveled an average of 8.7 miles annually since it was first delivered in 2008.
Currently, a similarly equipped CR that sold for $122,500 on Bring a Trailer back in February 2022 has the distinction of most valued S2000 in the world. However, the mileage on that vehicle was 5500 when it was sold. At the time of writing, Rahal’s CR had received bids as high as $111,111, and there were still three days left to place them.
Rahal has relocated an S2000 using the Bring a Trailer platform before. The six-time IndyCar race winner paid $48,000 back in 2018 for a pristine 2000 S2000 painted in red with 1000 kilometers on the odometer. The next year, he earned $70,000 by auctioning off a 91-mile example.
Is buying an S2000 worthwhile?
A fantastic high-performance roadster that is practical for regular driving is the Honda S2000.
For aficionados of sports cars and roadsters, the late 1990s and early 2000s were a brilliant time, as numerous fantastic models, including the Nissan 350z, Mazda MX-5, and of course the Honda S2000, were debuted. The Honda S2000 is still extremely desirable because it is still one of the best sports cars you can buy.
It’s a fantastic alternative for anyone seeking for a used roadster because to its renowned VTEC engine and classic design. There are a few drawbacks to purchasing an automobile that is 22 years old, though, because of its age. Before purchasing a Honda S2000, consider the ten items listed below.
