Very interesting. If you can make the part at a reasonable cost, and especially if it helps w/ NA, I'd imagine you'd get enough takers. Keep in mind (as I'm sure you're aware) the "extra" connections we have on our stock plastic manifold that need to be dealt with as well, e.g. the brake booster vacuum, the MAP sensor, the PCV vacuum connection(s), etc.
Even if you don't end up mass producing the part and just do a one-off for yourself, at least it will give us some independent data on the utility of the GTR manifold. Thanks for putting this up here
