If you know exactly how far you want to go with the car, it's a pretty good idea.
When most people start modding though, they aren't really intending to throw on blowers or nitrous
, etc. Most people just start with small things and end up deciding they want more and more. I think this is especially true for the V6 cars. Usually when someone buys a V6, it isn't with the intention of speed being a main priority.
