Hp?
GLT and T-5 use different turbos. Don't know what year you're looking at but the GLT uses a light pressure turbo and makes about 190hp. The T-5 or Turbo models use a high pressure turbo and make anywhere from 222 to 240hp.
Mainly exhaust and computer upgrade. Search this site and volvospeed.com and you will find plenty of information. Seems like people just keep asking the same questions over and over instead of looking through and searching for answers. Look for some replies and posts from S70driver he has put quite a bit on about upgrades.
Oh, then 222Hp is still good, what can i put in the engine so it can go faster?
Also a good note to make is that you shouldn't or well not shouldn't but a could idea not to do these upgrades until STAGE 0 is complete, read about it over on Volvospeed in their Performance PINNED section.
