a 2.5 with a sensible map about 1.3 bar boost and forged is a good lump , plus slow warm up and regular service , the torque is much greater than the 2 litre , and cars are a lot more driveable , use arp or like head bolts or the hg issue can return more easily , 2 litres are stronger but lack the torque , a 2 litre stroked engine could be best of both worlds but i don't know if there are downsides of stroking them ?
2.5 rebuilt right with a stand block will do 450 for years no probs. So really depends how far you want to go and what your plans are, a track car will be different to a drag car which will be different to a road car
