In the 4 cylinder world the Sr20 and the Mitsubishi 2.0 are the only engines I can think of that are made for boost from the factory from the start but also sold NA. VW's 1.8 is a variation of some other engine but I don't know enough about it to list it. Just because it's not made for boost doesn't mean in can't be boosted well. Honda has so much aftermarket support that you can do just about anything you want with the thing and do it well. Made for boost "NO". Boost friendly if you have the $. Sure

Edit: I forgot about the Toyota engine in the MR2.
