I own a FG xr6t and my mate just bought a BA xr6t (practically the same as what you're looking at). The interior of the FG is miles better than the BA, more functionality, ergonomic and easier to use and nicer, it should be on a newer car. Also the power delivery in the FG is astonishing, boost comes on early and hard, but you can drive it normally with ease, mainly because of the great ZF. If your not modding it (I'm assuming you won't because it's a family car) then it's a lot better to begin with, and if you do decide to mod it more power is very easy to come by. But mods wise the BF 2 will be better for big power, of that was what you are after. If funds permit I'd get the FG, plus you've already had a b-series why not try something new
