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 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.

The best K24 is…
The K24A2 is often regarded as the most remarkable K24 engine when it leaves the factory, but because of its high price, other varieties are more alluring if you’re not afraid to experiment with tune.
The K24A2 engine, which was used in the Acura TSX as well as the Honda Oddessey and the JDM Accord Type-S, produced between 197 and 205 horsepower and 164 and 171 pound-feet of torque.
Honda decided to alter the bottom end extensively for the A2, and the compression ratio increased to 10.5:1.
In contrast to the K24A1, they chose to use the i-VTEC system on both the intake and exhaust camshafts this time. Along with better cams, they also used lighter pistons, twin balancing shafts, a forged crankshaft, reinforced connecting rods, and lightweight components.
For the Acura TSX starting in 2006, the K24A2 received upgrades including a larger air intake duct (from 70mm to 80mm), a larger throttle body (from 60mm to 64mm), better intake valves, a new intake camshaft, and improved exhaust.
The result was the K24A2’s highest performance, producing 205 horsepower and 164 lb/ft of torque at 7,000 rpm.
The new modifications resulted in an increase in power from 197 to 205 hp, but a little decrease in torque from 171 to 164 lb/ft.
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.
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.
What Honda models included a K20?
Although the majority of owners have a definite choice, it’s totally logical given that both had benefits and drawbacks as time went on and the K20 matured.
The majority of K20 owners will counter that “displacement cannot be replaced,” and they have a point, particularly when considering naturally aspirated designs. But don’t forget that B18 race engines can generate more than 1,000 horsepower. Unfortunately, your stock K20 won’t likely be much of a match there.
In this article, we’ll concentrate on the K-series, a four-cylinder, four-stroke engine that chose to switch from the previous standard timings to computerized ignition timings. It had some advantages over its predecessors, including a more refined valvetrain and greater build quality, and an overall better design.
Honda had a reputation for counter-clockwise-rotating engines prior to the K20, but for the K20, Honda chose clockwise rotation to place the engine’s exhaust side toward the back of the car.
In 2002, the Civic Si, CR-V, and RSX were the first vehicles to include the K20 in their lineups. The goal for Honda was to create an engine that would satisfy current pollution regulations while also enhancing build quality and dependability.
Although you’ll quickly see that the K-series engine designations come in a great range, the majority of them are closely related to the K20A2 and K20A3 engines. Both have Variable Valve Timing and Lift Electronic Control (i-VTEC), however the valvetrains and VTEC implementation are where the primary differences lie.
Whether you want to buy a Honda or use the K20 in a different platform, it’s time to take a closer look at the many K-series vehicles to help you choose which one is ideal for your needs.
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 K-series engine has the maximum power?
Although Acura gave the TSX the larger K24 engine, the 2.0-liter RSX’s 2.0-liter i-VTEC head, with its higher flow rate, dominates the K-series engine world. For optimum tuning freedom, the i-VTEC features on both the intake and exhaust cams in addition to the bigger K20A2 ports. The valvetrain was strengthened by Loarca using a K20A2 head with Supertech springs and titanium retainers. With these upgrades, the valves are prevented from floating when the engine revs above 10,000 RPM. To ensure a tight seal, ARP head studs smash a Cometic MLS head gasket.
What Honda motor has the fastest speed?
Car Crate for a Civic Type R The 2.0-liter DOHC direct-injected i-VTEC Turbo engine in the Civic Type R generates a maximum 295 lb-ft of torque from 2,500 to 4,500 rpm and 306 horsepower at 6,500 rpm, making it the most potent Honda automotive production engine ever produced in America.
What makes K24A and K24A2 different from one another?
While the K24A just has intake side VTEC, your K24A2 has three lobes. As a result, you would likely require a new wire harness in addition to a new ECU.
