Everyone on this forum argues that for the price you don't gain any performance, to which there is a point, but in the end, so what? Look at my car, I've sunk thousands of my own hard earned cash into appearance mods that do absolutely nothing performance wise, if not actually hurting performance in terms of adding weight, and yet its justified.
If someone wants to spend their money to do a swap, then why hold them back? Besides, from the countless threads we've been through on this exact topic, the resulting mod could end up being done for cheap. And I don't mean $100, but with enough resources out there with junk yards, or websites like rock auto, someone could probably do the conversion for $400. And for someone who shows his car like me, $400 is more than worth it.
