Though I did assume disappointment at face value, I've been thinking about it over the past few hours and there really isn't that much space to put anything larger in the Z32 engine bay. This seems like an ideal shape to keep most things in stock placement and not interfere with the strut towers, engine mounts, etc etc. In all reality, it can be said that the MSP manifold is just slightly magnified version of the stock manifold.
We all see these manifolds on the outside but none of us know the flow characteristics on the inside. Since there's such a big upset over the matter, I can only hope for an indepth comparison between the two. Lets just hope that both of these are completely different.
