What engine does a 2004 Honda Civic Type R have?
The 2004 Honda Civic Type R uses Honda’s 2.0‑liter K‑series DOHC i‑VTEC inline‑four: the European/UK EP3 model is powered by the K20A2 (about 200 PS/197 hp), while the Japanese‑market EP3 uses the higher‑spec K20A (about 215 PS/212 hp). This distinction reflects market-specific tuning differences for the same EP3-generation Civic Type R.
Model context and market differences
The 2004 Civic Type R belongs to the EP3 generation, produced from 2001 to 2005. Built primarily in the UK, it was sold in Europe and Japan, but not in North America. While the chassis and overall package were similar across markets, Honda fitted different versions of its K‑series 2.0‑liter engine to meet regional performance targets and regulations, leading to the two commonly cited engine codes: K20A2 (Europe/UK) and K20A (Japan).
Engine codes and outputs
Below are the engine variants fitted to the 2004 Civic Type R, with core specifications that enthusiasts and buyers will typically encounter.
- Europe/UK (EP3): K20A2 — 2.0‑liter DOHC i‑VTEC inline‑four, rated around 200 PS (197 hp) at approximately 7,400 rpm and 196 Nm (145 lb‑ft) at around 5,900 rpm.
- Japan (EP3): K20A — 2.0‑liter DOHC i‑VTEC inline‑four, higher‑spec “red‑top” version, rated around 215 PS (212 hp) at approximately 8,000 rpm and 206 Nm (152 lb‑ft) near 7,000 rpm.
Both engines are closely related, but the Japanese K20A benefits from more aggressive cams and tuning, delivering higher peak power and a more pronounced high‑rev character compared with the K20A2 in the European/UK car.
Technical characteristics
Regardless of market, the EP3 Civic Type R’s K‑series engine is known for its robust construction and high‑revving nature. The key engineering elements that define its character are outlined below.
- Aluminum block and head with DOHC architecture for reduced weight and strong thermal efficiency.
- i‑VTEC system combining variable valve timing and lift with an intake cam phaser (VTC) for a broad powerband and a high‑rpm cam profile engagement.
- High‑rev capability with a redline around 8,000 rpm, emphasizing performance at the top end without sacrificing mid‑range drivability.
- Paired with a close‑ratio 6‑speed manual transmission; some market versions also included a helical limited‑slip differential to enhance traction under hard acceleration.
- Market‑specific intake, exhaust, and ECU tuning contributing to the output difference between K20A2 and K20A variants.
These features collectively made the EP3 Type R an icon among hot hatches, prized for its combination of mechanical engagement, reliability, and track‑friendly tuning.
How to identify your engine code
Owners can confirm which engine their 2004 Civic Type R has by checking a few locations and documents on the vehicle.
- Under‑hood engine stamp: The engine code (e.g., K20A, K20A2) is stamped on the engine block, typically on a flat machined surface near the transmission bellhousing.
- VIN/ID plates and service book: The car’s build plate and service documentation often list the engine code or market designation.
- Market of sale: Original European/UK cars almost universally have K20A2; Japanese domestic market cars carry the K20A.
Verifying the code helps with sourcing correct parts and tuning information, since some components and calibrations differ between the two variants.
Summary
The 2004 Honda Civic Type R (EP3) is powered by a 2.0‑liter K‑series DOHC i‑VTEC inline‑four. European/UK models use the K20A2 rated around 200 PS (197 hp), while Japan’s version features the higher‑output K20A at about 215 PS (212 hp). Both engines deliver the high‑revving, engaging character that defines the EP3 Type R, with differences largely driven by market‑specific tuning and components.

What Civic has the K24?
The Honda Civic Si from the 2012-2015 model years is equipped with the K24 engine (specifically, the K24Z7 in the US). This is a production model, but the K24 engine was also sometimes swapped into older generations, such as the 8th-generation (2006-2011) Civic Si, to replace the original K20 engine.

Factory-Produced K24 Civic Si:
- 2012-2015 Honda Civic Si (FG4/FB6): These were the factory-produced models that featured the K24Z7 engine.
K24 Swaps (Aftermarket Installation):
- 8th Generation (2006-2011) Civic Si: Owners often swapped a K24 engine into this generation’s Civic Si, replacing the factory K20 engine for more torque and power.
Why the K24?
- Increased Torque: The K24, being a 2.4-liter engine, provides more low-end torque compared to the K20’s higher-revving nature.
- Performance Upgrade: This engine swap is popular in the performance community, offering increased power and a more responsive driving experience.
