{"product_id":"2-4l-inline-4-dohc-i-vtec-engine","title":"2.4L Inline-4 DOHC i-VTEC Engine","description":"The Honda K24A-RBB engine represents a performance variant within Honda's esteemed K-series lineup. This 2.4L inline-4 DOHC i-VTEC unit is characterized by its RBB cylinder head, which signifies a higher-performance configuration compared to other K24A variants. The engine boasts a 10.5:1 compression ratio, enabling it to deliver robust power output, typically ranging from 190 to 200 horsepower and 164 to 173 lb-ft of torque. Its 3-lobe VTEC camshaft system further enhances its performance capabilities, allowing for a respectable 7200 rpm redline.\n\nOften found in JDM applications, the K24A RBB is closely related to the USDM K24A2 engine, commonly featured in the 2004-2008 Acura TSX. Key components such as intake manifold type, cam profiles, throttle body size, oil pump, and ECU behavior can vary between JDM and USDM models, as well as among different JDM K24A sources. The RBB head specifically indicates the presence of a performance-oriented VTEC system and generally aligns with higher horsepower outputs.\n\nWhen considering a K24A RBB for a swap or build, attention to specific details is crucial. Buyers should verify intake manifold type (aluminum suggests better airflow), cam cover and sensor configurations, transmission bolt patterns (some JDM variants come from AWD platforms), and the oil pump type (a high-flow version is recommended for revving past 7,000 rpm). Furthermore, ECU compatibility is a significant consideration, as a Hondata K-Pro or a standalone ECU is often required for optimal tuning and operation.","brand":"Honda","offers":[{"title":"Default Title","offer_id":52688693723448,"sku":"K24A-RBB","price":999.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/664206089.webp?v=1784893003","url":"https:\/\/store.motormia.co\/products\/2-4l-inline-4-dohc-i-vtec-engine","provider":"MOTORMIA","version":"1.0","type":"link"}
