    Rb26 head conversion on a Rb30 carby

    Hey guys,wondering if anyone can help me. I'm doing a head conversion on my Rb30 GQ 91,and need to know what I need to take off the Rb26. The Rb26 is in a R33 skyline and is turbo, Do I need to remove the complete head aswell as turbo manifold and throttle body ? Also do I need the ECU ? Appreciate any help,thanks.

    Going back a while ago my facts may not be straight but I looked at rb26 head into a rb30 when I had a skyline to make a twin turbo 3ltr. Think it is possible but some machining had to be done on the rb30 to get cam chain to clear. I'd imagine you would need ecu and all wiring as pretty sure they have vct.

    Big job from what I remember.
