I disagree. low boost you don't need an intercooler. Plenty of cars can run low boos pressure with no intercooler an be fine. It's about cylinder pressure and iat temps

5psi=50-60whp with a jrsc non intercooler. A k20 supercharged civic hatch would rape almost any car on here stop light to stop light.

If you go rotrex, you'll make the same power as a turbo setup without the high egt and iats

rotrex k20 guys are making 400-450whp same as a full race kit.
