And since this is a WTB thread - I have a stock sr20 intercooler core (no outlet/inlet pipes - might be able to find them) for $60 shipped.
And from yahoo answers putting it in lameman's terms for you:

"You can install anything you want. The real question should be: Will intercooling help performance of a non-turbo car. The reason for the intercooler is to decrease the temperature of the forced air generated by the turbo. Consider the fact that it is compressed air generated by hot exhaust gases which turn the vane in the turbo. By cooling the air generated by the turbo, you can increase the power capability. You can research air/air intercoolers and even water/ice/air intercoolers on yahoo search.
To answer your question, yes you could install one but you would likely see no performance gain and maybe even a drop. This is due to the additional volume added to the intake tract by the piping and intercooler itself. Your best bet is a cold air intake which you can buy from most any aftermarket parts place."
