The 4P K24Z All Motor race engine is perfect for those of you wanting a big boost in speed, but wanting to keep your car naturally aspirated.  We use an OEM sleeve K24Z block and fit it with Saenz connecting rods and armor plated Wiseco 12.5:1 compression pistons.  Power and rpm capabilities are dramatically increased with use of our CNC Ported Pro R40 cylinder head and billet R403 camshafts.  This cylinder head flows a massive 360cfm, and the single port exhaust is maximized to even outflow commonly swapped 4 port Type S heads.  This allows for big power and the high rpm you love from K20 based engines, but in the single port orientation.
