Stage 3

Stage Three is the final of our 1,300 horsepower rated packages, where the only things that remains untouched is the crank and block itself. All items in the rotating assembly and cylinder head have now been replaced with stronger and more durable items including that last remaining OEM item, the valves themselves. Ferrea 1mm OS valves take seat inside the upgraded Ferrea Dual Valve springs. Additionally, the VR38 cylinder head will be modified to increase the volume of air and smooth out internal ports.
