thanks that would be great ,also if theres anything else off the k20z4 engine that i would have to useI'll,ask a buddy of mine in the USA I am almost certain that's the head on his Frank, we featured his car in Fast Car a few issues back. Phil Nguyen. I'll send him a message on FB.
Nice links. Interesting read on that FN... I was just gonna add my buddy in the States said he'd spoken to a guy that had built a frank with the Z head.
