Not to get too far off the build, but I have a 4bta and an NV4500 as well for one that I hope to do sometime down the line. Saw one done recently that actually used the stock EB vacuum booster hooked to a factory 6bt vacuum pump. Thought that was a good idea. Not sure if I'm going to do that or go hydroboost.
