RSX (Civic Engine)
I'm a newbie to this forum...was told the RSX has the same engine as the civic. Anyone care to ellaborate?
I'm looking into purchasing a new RSX. Thanks.. |
the civic si hatchback has the same k20a3 motor as the base model rsx
hope that clarifies things |
and the TypeS has an engine that is similar, but produces more HorsePower.

I'm looking into purchasing a new RSX. Thanks.. The EP3 Civic SI hatchback has a detuned version of the base RSX engine. No other (stock) USDM Civic is sold with a K series motor. While the base RSX engine is a nice smooth high quality engine, it doesn't have the third cam profile that the K20A2 (Type-S engine) has and as a result doesn't have the top end power. |
i dont think they detuned the k20a in the EP Si
i think they are rated the same @160 bhp in BOTH the base rsx and Si |
Special note: The K20A3 engine used in the Acura RSX base has a slightly different intake manifold design from the K20A3 engine used in the Civic Si. The RSX engine uses a dual-stage manifold, similar in concept to the manifold of the B18C1 in the old Integra GSR. It uses long intake runners at low-RPM to retain low end power, and switches at 4700RPM to a set of shorter intake runners to enhance high-end torque. This accounts for the extra 9 ft-lb of torque in the RSX (141 ft-lb, vs. 132 ft-lb in the Civic Si).
