K24A Engine

Honda K24A (Z, Y, W) 2.4L engine

 

K24 engines, created on the basis of K20, from Honda have replaced F23 engines. Its difference from the basic K20 consists of a crankshaft with an increased stroke of pistons, an enlarged cylinder block and an enlarged diameter of the pistons themselves. All the rest remains unchanged, the same chain, balancing shafts on individual motors, the same variable intake geometry and the absence of hydraulic expansion joints.

K24A engine problems

As part of the weak points, the K24 is totally comparable to its junior engine – K20: camshaft wear, oil leaks, floating speed and rpm, etc.

Honda K24A Engine tuning

General options to increase the impact: increase turnover, inflate it by the compressor or blow it with a turbine… These methods are the same as for the K20 engine.
