Description
The 4 Piston Racing K320 Crate Engine provides the ultimate performance and reliability for your street or race car. The best part is, NO CORE REQUIRED and no wait time. These are built from brand new K24A engine cores and you don’t need to wait for them to be built. They are in stock!
This 2.4L Naturally Aspirated engine offers a smooth idle and daily drivable street manners. When you are ready to roll into the throttle, the engine is full of low end punch and comes to life with Honda’s i-VTEC system. The high flow CNC cylinder head and high lift camshaft allow this engine to accelerate its 320hp aggressively beyond 9000 rpm. Lean into the throttle on an open road and the power and sound experience is liberating. All this with the peace of mind that you are commanding a durable and reliable engine. Power level is quoted based on pump gasoline and popular street induction and header. Race pieces will increase output.
