Your build will possibly end up somewhere in the 12-15k range; EK1 ~5k + B18CR front cut ~6k + your suspension that you've already got ~1k + possible brake upgrade ~1k if you go dc2r 5-lug +labour
Ek's are nice, but with the prices of some dc2r's around, I'd be more inclinde to buy a 'teg like many others have suggested. You'll have luxuary of a/c, power windows/mirrors, 5 lug, recaros, no sound deadening to remove etc.
Too many pros to ignore!
