The intake'll let you make use of more power from less boost as well as keeping the intake path nice and short so that lag is virtually eliminated. You still have to size your turbo for the boost threshold you want, but I find that if you port the exhaust to open ten or so degrees earlier, you'll spool it much faster. (ie, the turbo 12a I had would make positive pressure at 3000rpm and was boos.......ime. A gigantic wastegate set to ~9-10psi would help alleviate that, though. More boost than that and you'll have backpressure issues no matter what you do.

Actually the idea of running an air-water inter-fooler didn't even cross my mind. Might be a worthwhile option since i could use some good cooling aids. Only downside is there is a lot more complexity to it and possibly weight. My other option was to run a standard intercooler (cheaper and simple) and run a CO2 fogger on it with a larger bottle.
I'm probably going to run the stock intake manifold system, at least for now, mostly due to funding. The cage is going to come in at about 3200 dollars, so there is some other costs i need to handle first.
I am thinking about running the intercooler and radiator in a v-mount because i feel i could get better cooling and the units could be better protected when the skidplate is placed. Plus there would be little charge pipe to worry about.
As far as a turbo goes, i can get a very small T4 (even down to .69). So will have to play with it. In regards to heat and the testing different setups, i might just run master power turbos and just replace them cheaply when i either destroy one or want to try another setup.
