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 a K24Z block and fit it with Ductile Iron Sleeves for 2.5L of displacement, 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.
