correct me if im wrong, but isn't that a 4g63, lol, wrong section?
BUT, anyways,
You could change up the valve cover, radiator hoses, fuse box cover, radiator hinges, ss braided lines everywhere, they are blue and red but still they give a very professional legit look...no if your really serious, then you can powder coat, turbo flange, all the brackets on the car, like the a/c, powersteering bracket, you could also powder coat the UDP. now, if your really really really serious lol, you can give your engine bay a wire tuck under the the fenders...just my two cents...
