My car was originally hot-air (hence the screen name). But since then, I've gone through many pains to make it an intercooled car. I have nothing against hot-air cars, but as I look back now, it's a matter of "wish I knew now, what I didn't know then".
A lot of great things can be done with hot-airs. Both in performance and collectibility. But, you have to look at the long term picture. For me, I didn't know much better until AFTER I bought the car. So, now I have what I probably wanted originally, but at great expense and a lot of wrenching.
