Im super stoked as well. I'm most interested in seeing the odds n ends of the kit, like the coolant feed/return lines for the water cooled garrett based turbo, and the other hardware like gaskets, nuts, bolts, barbs, vaccum lines, if there is a mac solenoid, etc... as well as the air intake tubing and "hotside" intercooler tubing as well and of course seeing how the downpipe and wastegate dump tube turns out (which im sure will be awesome considering who the fabricator is)
In addition Im very interested to seeing how good these custom turbos are, after talking to John privately it is said they are just as good as genuine garret and only real differences will be cosmetic (basically no "garrett" name on the housing) and I don't doubt that, but seeing some data/results/people running these turbos just for re-assurance would be super nice as well!
