Quoting vr4junkie:
All in all how difficult was it to install any welding,cutting, making brackets, any thing have to go in order for it to work?
As for performance, the long and short is that you want the two cores (intercooler and heat-exchanger) to be "roughly" the same volume, with an emphasis on the intercooler which should be as big as you can fit in order to instantly transfer heat into the water. The front heat exchanger can then radiate that heat over a prolonged period so it doesn't have to be as big. When people say they're not good for DD, they're usually thinking of running a big ice-bath and no front heat exchanger. That's not what we're doing here.
Installation is a pain in terms of the tetris aspect, but simpler than fabbing an FMIC and, if you put the HE where your AC condensor used to be, requires less cutting than an FMIC job. And you get the benefit of an ULTRA-SHORT intake path which makes for fantastic tip-in throttle response.
Total investment, if you do it right the first time /ubbthreads/images/graemlins/banghead.gif is going to be about the same as a prebuilt kit. Figure $300 for the two intercoolers, $200 for the pump and reservoir of your choosing, $100 for turbo outlet pipe (either custom or modified prefab), and then $1,000,000 for couplers and miscellaneous fittings. You'll also need a bracket to support the intercooler (mine is an ACE turnbuckle mounted to the transmission) and a bracket to hold the HE in place (mine is a pair of aluminum sheets with holes drilled that go to the front cross-member and hood latch bracket). I'll take some pics when I get home tonight.
