Have for sale a complete R33 RB25 variable cam timing head.
Has been ported to remove cast marks and restrictions mainly in the bowls behind the valves. Has been decked and combustion chambers smoothed out & cc'd. It has been modified to be used with an RB30 block with the vct pluged and redrilled and tapped with a fitting for external oil feed line. There was also a small amount of weld at the coolant gallery at the edge of the head to allow more contact area for a better seal on the RB30 block.
It comes with all sensors, wiring, coils, injectors and rail, all covers, inlet manifolds, cams, springs, Lifters and valves. Everything for a conversion to RB30DET.
This mod can also be reversed for normal RB25 use if required.
Was going to use it on my own block however I have decided to go a different way. After $1000 ono
