2009 GT-R Cylinder Head Porting

 

We recently ported a set of cylinder heads for a customer building a 1000hp VR38DETT engine for his 2009 Nissan GT-R.   We found some definite room for improvement in both the intake and exhaust ports with the exhaust ports responding best to the port work.  Final flow numbers will be available once the heads have custom valve guides installed and a very trick valve job performed.  We’ll also have some more pics once the chambers have been ceramic coated.   Here are some before and after pics of the heads.
