i assume you want to drive this on the road. if you want it just to race on a track, then you can do that. if it's not being driven on the road then it doesn't need to pass crash testing or emissions.
however, if you do want to drive it on the road, you have to have it legal. if you don't you could get in very big trouble with the law.
the biggest obstacle will come when you try to register the vehicle. your DMV will be able to pull all the info on the evos, and if it's not deemed roadworthy it's state when you have it tested, you won't get it registered.
over here (Britain), we have what's known as SVA testing (single vehicle apporval) which is when you bring a grey import into the coutry. i don't know about crash testing, but thing like emissions and lights are tested, often resulting in retro-fitting of seperate fog lights (rear fog lights are required by law here) and the like.
