Re: 230K Engine swap?
You have a vehicle with a gorgeous body and an engine that can run 200-300k miles with reasonable maintenance. You want to jeapordize that for something that, at the end of the day, will be a little faster and a lot less reliable. Go ahead, but don't ask us which is better or cheaper because we don't recommend it. And if you have to ask "how much", you can't afford it. You might want to consider a beater WRX and mod the crap out of that. Then you can enjoy your XF for what was meant to be, a solid, peppy (but not quick) sports car. But it is fast -- mine easily breaks 140 before I run out of road/guts. PS-Yes, Audi's can be modded (I have a chipped A6 2.7T with >300 hp) but don't get those owners going about the cost of parts and repairs. The more power you make, the more frequently other things break. It's like bog-running in a jeep (another youthful passion), another expensive hobby.
