Does the 2006 Acura TSX have a K24?
Yes, the 2006 Acura TSX was equipped with a K24 engine. The K24 is a 2.4-liter inline four-cylinder engine that was commonly used in various Honda and Acura models during the 2000s.
Detailed Overview of the 2006 Acura TSX Engine
The 2006 Acura TSX was powered by Honda's K24A2 engine, a 2.4-liter inline four-cylinder that produced 205 horsepower and 164 lb-ft of torque. This engine was part of Honda's K-series engine family, which was known for its high-revving performance and excellent fuel efficiency.
The K24A2 engine in the 2006 TSX featured the following key specifications:
- Displacement: 2,354 cc (143.6 cu in)
- Bore x Stroke: 87 mm × 99 mm (3.43 in × 3.90 in)
- Compression Ratio: 10.5:1
- Valvetrain: DOHC, 16 valves
- Fuel System: Sequential multi-port fuel injection
- Aspiration: Naturally aspirated
The K24A2 engine in the 2006 TSX was paired with either a 6-speed manual transmission or a 5-speed automatic transmission, both of which helped deliver responsive and engaging driving dynamics.
Acura TSX Engine History
The Acura TSX was introduced in 2003 as a compact luxury sedan, replacing the Acura Integra in the brand's lineup. For the first generation of the TSX (2003-2008), the K24A2 engine was the sole engine option, providing a balance of power, efficiency, and refinement that was well-suited to the TSX's sporty yet premium character.
In subsequent generations of the Acura TSX, Honda continued to use various K-series engines, including the K24A4 and K24Z7, to power the vehicle. However, the 2006 model year marked the peak of the K24A2's use in the TSX, as it was the final year of the first-generation model before the redesign for 2009.

Which Acura TSX has the K24?
The 2004-2014 Acura TSX model years all use a version of the K24 engine, specifically the K24A2 in the first generation (2004-2008) and a variant of the K24 in the second generation (2009-2014). The second generation TSX's K24 engine produced 201 horsepower in 2012, with a 2.4-liter inline four-cylinder DOHC i-VTEC engine.
- First Generation (2004-2008): The K24A2 engine was used, producing 200 horsepower.
- Second Generation (2009-2014): The second generation continued to use a K24 engine, with some later model years featuring a 2.4-liter i-VTEC variant producing 201 horsepower.
Does K24 have VTEC?
Yes, all Honda K24 engines have some form of VTEC, which is integrated into the system as i-VTEC (intelligent Variable Valve Timing and Lift Electronic Control). However, some versions of the K24 use VTEC on both intake and exhaust camshafts (3-lobe VTEC), while others only have it on the intake side. The version with both intake and exhaust VTEC is generally considered the high-performance version.
K24 engine VTEC variations
- High-performance K24s: These versions have VTEC on both the intake and exhaust cams, providing greater performance across the RPM range.
- Economy-focused K24s: These models have VTEC on the intake side only, prioritizing fuel efficiency over top-end power.
Is K20 or K24 better?
Neither the K20 nor the K24 is inherently "better"; the choice depends on your goals. The K24 offers more torque and is better for daily driving due to its larger displacement, while the K20 is more "rev happy" and has higher peak horsepower potential at higher RPMs. A popular high-performance hybrid is combining a K24 block with a K20 cylinder head to gain the benefits of both.
K24
- Pros:
- More low-end torque and power, making it more driveable for daily use.
- Greater peak power potential due to its larger displacement.
- Often more affordable to acquire.
- Cons:
- Has a lower redline and is less "rev happy" than the K20.
- Some base models lack high-performance features like piston oil squirters and a high-flowing head, requiring modifications for maximum performance.
K20
- Pros:
- Has a higher revving nature and can produce more horsepower at higher RPMs.
- Smaller displacement makes it ideal for lightweight chassis.
- Cons:
- Lacks low-end torque compared to the K24.
- Can require more modifications to reach the power potential of a stock K24, especially for low-end torque.
Hybrid option
- K24 with K20 head: A common and effective build is to use a K24 block (for its displacement and torque) with a K20 head (for its higher revving characteristics and better airflow). This combination provides a good balance of both engines' strengths.
