you know, this is pretty UN-orthodox thinking, but unless you are tracking a car; as in sustained high rpm's and boost pressures, an intercooler is pretty well useless unless you are doing water injection and/or methenol/nitrous fogging. As an example, a good friend of mine has a 510 with an S13 powerplant and a GT28RS @ 12 psi that makes 235hp all day long, and you can't really even stay in the boost long enough for any kind of I/C to make a significant difference. Steady 100-120 IAT in lower alabama, and the car is just too fast to exceed acceptable intake temps and thus justify an intercooler. You literally dont have the room on the road to justify it. How long can you keep your foot to the floor on any public street or highway? 10-15 seconds, maybe 25 seconds on a nice stretch of highway. How long in the boost does it takes your car to exceed 180-200 IATs? Another friend of mine uses water injection on a FD3S with stock twins and a nice(very nice) homemade IC with a fan that when coupled with the water injection, IATs will match or be slightly below ambient temps. Very effective indeed, but "necessary"? On a rotary maybe, SR's; not really. Do you really need the extra weight associated with a FMIC and plumbing? Throttle response is amazing with a 24' charge pipe. I/Cs obviously work, but at what point do you REALLY need one? Just sayin....
