We have been working with Motovicity for the last few weeks to demonstrate the building of a potent Honda K24Z7 motor, built completely from in stock and off the shelf parts available from Motovicity themselves. We chose the K24Z7 as it is currently the OEM engine for the Civic Si and is relatively difficult to modify due to it's emissions bound cylinder head. Our goal is not to build a dyno queen or a drag motor but to build a strong K motor all from off the shelf parts with the intention of getting the most power possible on pump gas with the widest most useable powerband.
In the last two editions of our series we focused on the cylinder head and bottom end of our K24Z7. We swapped to an earlier model K20Z3 head to get Vtec on the exhaust side and and removable exhaust manifold and installed Skunk2 camshafts, Kelford valvesprings and Supertech valves better suited for turbocharged use. For the bottom end we added lower compression JE pistons and stronger K1 rods, removing the problematic balance shafts while we were in there.
Now it's time to finish off our motor.
