what about spool times? someone told me that you just cant slap on the biggest turbo money can buy on your car because it wouldnt spool the turbo until theres X amt of exhaust pressure. anyone want to explain? is that also why the 28 spools slower than the 25? because of bigger housing? and is better for high rmps becuase of the exhause pressure is higher?

ok here we go again haha. turbo size is all relitive to size of the engine and modifications to the engine. if you took your msp and put a gt40 on it that thing would not even spool because you arn't running enough boost and you dont have a strong enough motor if you check out those links i post it list the turbo and egine size suggested and horse power those are all things to take into account when buying a turbo. You are correct in you thinking to you do need a certian ammuont of exhaust gases to push the wheel of your turbo charger a gt40 wouldn't spool until probably 5k in our cars haha
 
if all you want is 230 you do not need a turbo or to upgrade the internals in it. I have 230 right now on the t-25. with few mods and a horrible tune. I just have a fmic, twiggy cams, cai, microtech ems. I am unsure what the boost was on when it was on the dyno but I think around 10 or so.
