Boostin Performance CNC Ported Stage 3 Cylinder Heads (R35 GT-R)- 1500WHP Rating
Our Boostin Performance R35 GT-R Stage 3 Cylinder Heads are designed to facilitate big power! Both intake and exhaust runners are CNC ported and smoothed out for maximum flow. In addition, CNC recontouring of the combustion chamber further reduces unwanted turbulence - retaining optimal fuel atomization leading into the cylinder. Overall, this CNC program ensures the very best results are achieved from the Nissan OEM cylinder head design. It is a proven formula that has even been tested to over 2500HP with excellent results and can be found on some of the world's quickest and fastest GT-Rs!
Only the highest quality components are fitted into our cylinder heads. New 1mm Oversized Valves are installed along with a new set of Valve Seals, Titanium Retainers, Upgraded Valve Springs and a new set of Kelford Cams. Each valve is then lashed separately and Custom Buckets are fitted.
