staffi dont know what the bhp limit is on the turbo sorry but i whould say the lag is about the same, just dont come in as hard as the T34 but the T38 pulls a lot stronger if you know what i mean.
foreigneRS its on P8 mate
yum good luck with your new engine mate, that will be mad on the road

i know the sort of cost an engine and all the other bits cost to go with it and i hope it all goes to plan for you and i will try and blag a ride when its all sorted
