I think direct port would be much easier to setup if there were more aftermarket intake manifold options. I am working on a side project to design and make a new intake manifold that would allow for easy direct port setups.
I run a 3D scanner at work. I have the lower intake scanned in. Will be doing the upper next week and a scan of both together so I can get the dimensions into solidworks. Id like to design something that mounts in the stock location so the throttle bodys, intake pipes and strut brace still fit like stock.
