Is there an 8th gen Honda Civic Si?
Ensuring the new power plant maintains all original 8th gen Civic Si hoses, belts, and harness with no modifications allows for easy part sourcing and future maintenance. We wanted to build a K24 8th Gen Si, for long lasting daily driving, the way Honda would have built it, an OEM+ K24A 8th generation Civic (FG2/FA5) build.
What kind of power steering does a Civic Si use?
Most RBB K24A engines use a traditional hydraulic power steering system unlike the 8th gen Civic Si which uses an electric power steering system (EPS). A serpentine belt idler is found in the K20Z3 and all EPS K series engines in place of the power steering pump, similar to the USDM Honda Civic EP3 K20A3 engine.
What kind of engine does a Honda Civic use?
While the engine does not maintain the square bore/stroke ratio that allow the K20’s to easil achieve 10k RPM glory, the added torque (+ 30 lb·ft) due to the deep stroking 2.4L adds… The JDM RBB K24A engine is a “3 lobe” VTEC engine with 10.5:1 compression similar to the 2004-2005 USDM Acura TSX K24A2 engine.
Can a Civic Si be converted to a K24A?
The RBB K24A in it’s original state does not plug and play into the 8th gen Civic Si chassis, it requires using certain parts from the K20Z3 engine for a plug and play conversion. Luckily the RBB K24A head and block accept all the K20Z3 components needed without any modification or after market adapters, a happy Honda coincidence.
