stock T25 is only good till around 18PSI stock fuel is good till about 16-17PSI the 14B (stock 1G turbo) is good till about 19-20PSI but is more efficient and a better turbo than the T25.

the EVOs can boost 22PSI on the stock 550s so I gues they are good, but dont forget a fuel pump too... and to have it run to its top potentcail adding fuel and and boost wont do getting a tune will work wonders with that stuff
