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.
What vehicle features a K24 engine?
The Accord, Element, and CRV from 2003 and later all come with the standard K24. You can also find a cheap manual transmission in the Accord.

Is the K24 Honda engine reliable?
It might sound monotonous, but the K24 is a genuinely good, dependable engine. It is widespread and may be found in numerous Honda and Acura cars. Oil leaks from the front main seal, exhaust cam galling, and timing chain tensioner failure are the three most frequent issues. Certain K24 varieties might be more or less prone to these issues. Additionally, they are three of the most typical concerns on the K24 rather than necessarily prevalent issues.
Your Honda K24 should be quite trouble-free for its expected lifespan of 200,000 miles or more if you take good care of it. In general, be prepared to maybe encounter a few problems along the way, especially as the engine matures. However, the K24 will likely last a very long time as a dependable and enjoyable engine.

Which Honda models have k20 engines?
Honda first unveiled its K-series engine family roughly two decades ago, and a lot has changed since then. There have been numerous modifications and upgrades, which can make them difficult to track. For your convenience, we’ve easily split them down in our history section.
You already know that not every K20 engine is the same if you’ve read this far. You might have been better off sticking with the B-series if you choose the incorrect one.
The world currently places more emphasis on cleaner emissions and fuel consumption than performance and tuning possibilities, so choosing the most recent powerplant may not always be the best choice. A lot has happened in the nearly two decades since the K20’s introduction.
When everyone recognized that the world wasn’t going to end due to the “millennium bug” at the tail end of 2000, Honda had a trick up their sleeves that they were almost ready to unveil to the world.
The JDM-exclusive Honda Stream was the first vehicle with a K20A engine to hit the market. This engine would go on to become the ancestor of a number beloved engines, including the B16, B18, B20, D16, H22, and F20. Whether Honda devotees liked it or despised it, a new era had begun.
The B-series developed a cult-like following over the course of its twelve-year life, which would soon erupt into e-wars as the owners of the K and B series duked it out online over which was more remarkable.
K24 – a VTEC?
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).
Why is K24 so well-liked?
The Honda K24A3 and K24A2 are interchangeable. In other international markets, it had a different name. Nevertheless, it was the identical K24A2 that the Acura TSX utilized from 2004 to 2005 and not the upgraded model used from 2006 to 2008. In other words, it was excluded from the minor power gain caused by changes to the intake and exhaust systems. Thus, at 200 horsepower and 171 lb-ft, power and torque remained relatively close.
Due to their identical architecture, the K24A, K24A2, and K24A3 continue to be the ideal out-of-the-box swaps for hobbyists seeking the least amount of labor.
Honda K24A1
We’ll discuss the more cost-effective K24 designs in order of when they were released, starting with the K24A1. In the CR-V from 2002 to 2006, it was the first engine Honda released in the K24 series. The 160 horsepower and 162 lb-ft of torque this engine produced don’t seem like bad numbers until you remember that it was one of the original K-series engines.
When compared to the K20 engine it replaced, the K24 also delivered advancement in the form of stronger connecting rods and upgraded crankshafts. The K24A1 engine continues to be a popular option due to its availability and cost, despite not being as performance-oriented as the aforementioned engines. The fact that the cylinder head may be easily ported to increase airflow is another important factor in its consideration.
The K24A1 can be retrofitted with parts like the oil pump and head from the K24A2 because it is pretty closely linked to the most widely used K-series.
Is the K-series superior to the B-series?
The K series, according to Rodcharoen, is superior by a wide margin because it features a head that flows at a higher CFM, roller rockers, and a larger displacement. The K-series and B-series have a smaller difference in forced induction.
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.
What Honda engine performs the best in racing?
But the decision for the top slot on the list was comparatively simple. Even while the high RPM power and output per liter of the B and K-series four-cylinder engines are remarkable, there is one Honda engine that is marginally superior.
That would be the F20C, which was created for the Honda S2000 roadster with rear-drive. The 2.0L F20C, which was packed with racing DNA and produced an astounding 240 horsepower, ranks among the highest specific output production engines of all time. The S2000 became an instant classic as a result.
Of course, the bigger F22C, which debuted in the AP2 model a few years later and had enhanced low-end torque at a somewhat lower redline, is in some ways the superior engine overall.
However, the original F20C is our choice for the best of the best when it comes to sheer engineering brilliance.
What Honda engine has the most power?
Even if high-rpm flogging is not necessary, it makes for storming fun as the 2.0L turbo 4-cyl. cranks out 306 hp before hitting the redline at 7,000 rpm. This VTEC engine is the most potent street-legal Honda to ever enter America, with a specified output of 153 hp/L.
What vehicle has a B20B engine?
The B20B and B20Z were reintroduced by Honda in the first-generation Honda CR-V. (1996). The B16/B18 family and the B20/VTEC engine development by enthusiasts were more closely modeled in this generation of the B20B and B20Z.
What vehicles include an H22 engine?
only H22A DOHC VTEC in Japan
- H22A-1000001 Si Vtec; Si Vtec-4WS discovered in Honda Prelude BB4-BB6 from 1992 to 1996.
- between 1994 and 1997 H22A-2000001 Honda Accord SiR Sedan CD-6
- created in 1997 SiR Wagon CF-2 for a Honda Accord.
- found in Honda Prelude models BB6–BB8 from 1997–2001.
- in Honda Accord/Torneo Euro-R CL1 models from 1999 to 2001.
What kind of motor is in an S2000?
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.
