Vehicle Fitment

This full powertrain swap is highly compatible with the following chassis:

2004-2008 Acura TSX (CL9): Direct fitment (Requires minor wiring adjustments for USDM compatibility).
2002-2006 Acura RSX Type S: Popular high-compression upgrade.
Honda Civic (EG/EK/EP3): Ideal for high-end K-Swap builds (Requires swap-specific mounts and axles).
Honda Integra (DC2/DC5): Direct performance alternative to the JDM DC5 Type R engine.

Installation & Technical Notes

Wiring & ECU: The included JDM Euro R ECU (RBC-specific) is programmed for the 2.0L displacement. If installing into a USDM Acura TSX, we recommend using Hondata K-Pro or a KTuner system to account for local fuel octane and emissions sensors.
Intake Manifold: Features the high-flow RBC intake manifold from the factory. If swapping into an RSX, verify hood clearance.
Drive-by-Wire (DBW): The CL7 Euro R uses a mechanical throttle body. If your vehicle is Drive-by-Wire (like the 06-08 TSX), you must use an adapter or convert to a cable-actuated throttle.
Axles & Hubs: In TSX applications, your factory 36mm axles are compatible. For Civic/Integra swaps, use K-swap-specific conversion axles.
Service Recommended: For optimum performance, replace the following prior to installation:
- Timing Chain Tensioner: (Upgrade to Toda or Hybrid Racing for track use).
- Spark Plugs: NGK Laser Iridium (Grade 7 or 8).
- MTF: Use Genuine Honda Manual Transmission Fluid (3 Quarts).
