something else to make your life a lot easier will be to ditch the B16 idea, which happens to be ILLEGAL in the state of california, and get yourself a B18 of some sort. As easy as the B16 may be to find and get running, you really don't want to hassle with the State laws and risk losing your car, losing the engine, or losing your license for driving an illegal vehicle.

Why do you want the JDM front end? You don't need it unless you're putting in something like a B18C (GSR) that sticks up past the fender line in a CRX. Other than that, any non-VTEC B18 or a B16 will sit in the right place. Don't spend money you don't have to, or at least spend money on performance first. Then worry about looks.
