GT1R Cylinder Heads Nissan GT-R 2009 - 2017
A GT1R cylinder head package is a great way to top off a killer VR38 short block. We offer 3 stages to suit builds from mild to wild.

Our Stage 1 package includes a complete freshening of the cylinder head. The head is fully disassembled, cleaned, and inspected. Valve seals are replaced, a fresh valve job is performed, and the head is re-assembled with Ferrea high rpm valve springs and titanium retainers. This package does not include any porting. The Stage 1 package will not increase power, but it will increase rpm capability to 9000rpm (assuming the block and supporting components are up to the task) and ensure the heads are fresh for a new engine build.

The Stage 2 package adds our CNC porting to the mix. The CNC porting optimizes the intake and exhaust ports for increased airflow, which improves power, torque, and boost response. A big advantage to CNC porting vs hand porting is consistent results with equal flow in all ports, every time. We recommend this package at a minimum for anyone looking for big power. HP gains will vary based on many variables, but a Stage 2 head package with our GT1R camshafts will generally pick up in the neighborhood of 50-100hp while improving response and widening the powerband considerably.

The Stage 3 package adds Ferrea stainless steel oversized valves and bronze valve guides. The oversized valves improve airflow and the bronze guides increase reliability. This cylinder head package has been run to over 9500rpm and 2000hp and is what we use in most of our GT1R Long Block packages. HP gains over the Stage 2 cylinder heads are generally in the 15-30hp range and reliability is improved in extreme applications.

All cylinder head packages require cores to be supplied or a $3300 core charge will be added for a new pair of heads and cam buckets.

Stage 2 and 3 packages include setting valve lash if cams are supplied or purchased with the cylinder heads. We offer/recommend our GT1R camshafts for most app
