K20A3

* Found in:
o2002-2005 Honda Civic Si
+ Displacement: 1998 cc
+ Compression: 9.8:1
+ Power: 160 hp (119 kW)* (119 kW) @ 6500 rpm

+ Redline: 6800 rpm
+ (* Horsepower and torque calculations reflect new SAE J1349 procedures revised August 2004)
* (The intake manifold is often credited with being responsible for the difference in HP between these two variants. The Civic Si being equipped with an aluminium intake manifold, and the RSX Base model equipped with a plastic version).

(The base rsx makes 10 more lbs of torque then the Civic Si due to the fact of the "plastic" intake manifold and it is a dual runner]

Other Facts:

06 - K24 has oil squirters as well as the RDX 2.3 motor. Previous K24s do not have oil squirters.

05 K20z motor has cam shaft profiles like that of the K20A motors, hence the bump in hp over previous years.

06 K24 motor has some better cams than previous years as well. Along with wider rod jurnals making for a stronger bottom end.

06 K24 motor is the motor to have for swapping, if you got the bones!

Longevity of a K24 race motor is better than a K20 b/c of its lower piston speeds required to put the same if not more hp/trq under the curves.

Here is a good article that lightly hits on the pains of the 06+ Si. MAF RUBBISH!

if its not a k....throw it away!
