why do you need 4 doors? family man?
if your not a family man, and your looking at car's of this calibre, what are you waiting for....r32 gtr, 400hp, street built, circuit ready. can pick up a nice one under 30k, 10-20k worth of mods and you'll be a *shitload* in front of any other car on that list.
if you want a 4 door, you seemed pretty cashed up, and you're not a family man and can compromise a little bit of practicality, then there is no question - EVO 5 or above. 5's you cant compliance, 6's you'll have to budget ~50k, 6.5 's budget up to ~55k to get onroad...
if you're family man, after practicality and still want 4 doors and performance then get the WRX (but which model? GC8? getting pretty old now), personally the version 6 STi (for about 40k these days) is a better bang for buck than an version 8 STi at 60k IMHO. 10k of mods on a version 6 and you'll be way infront of the version 8.
everything else IMO is boring as batshit...
