Everything looks good on paper, but can you actually do these mods is the question. I used to want to build up my 420a, then I got a TSI AWD and have a monster motor for it, now I'm back to wondering what to do with my 420a. If I were you, go ahead and build it up, there aren't that many of them out there and you'll have something a little more "out of the norm." Or you could do a 4g63 swap like I'm seriously considering
