So was contemplating install an rb26 manifold and itb setup on my rb25det neo. I see otaku garage has an adapter plate setup in order to do so.
My idea or question is why wouldn't it be easier to take the factor rb26 flange that bolts to the head, have it redrilled to match the rb25 bolt pattern and maybe have the rb26 bolt pattern filled in with weld?
Does this sound feasible?
