The NEW 4P Pro 2JZ CNC cylinder head is the ultimate cylinder head for your 2JZ powered street or race car. We spent countless hours balancing airflow to make sure this port is the best on the market. It not only flows great CFM, but it also has the proper air speed throughout the port to get the fuel and air where it needs to be for efficient combustion. The 4P four valve formula is proven across every platform we touch, and that is why to see our name topping world record efforts across all forms of motorsports. The 2J market will be no different. We didn't just put effort in on the flow bench, we put these on the race track long before their release to make sure they were perfected for your 2JZ engine. Our method with stock sized valves will outperform others with oversized valves, and we will give you camshaft centerline advantages that will translate to quicker acceleration.
Note: Porting available for VVT-i and Non VVT-i Cylinder Heads
Pricing is with YOU sending YOUR cylinder head in for porting. We may have cores available for purchase. We will add those as an option as we obtain good heads.
