There's an import shop up here in Portland that deals with strictly Nissans, Subies, and Hondas, and they have Integra clips and CTR clips, with and without motors in them, as well as all kinds of other JDM parts, (lug conversion, jdm fenders, etc) I'd look for some type of shop like that around you. I was actually surprised that there was a shop like that in Oregon, considering there isnt actually a huge market for Imports, and there's literally NO meets up here. But I'm guessing if we've got one, you might too. I'll try to see what kinda prices they've got as far as CTR clips and if they've got a website i'll upload the link.
but I definitely recomend going all out.. ctr front clip, with the ctr motor. make it a type r clone.
