I know going to just one big turbo would save u weight on increase power.. There is a guy that i know from Team ECI, out here in FLorida who did it on his TT Supra.. now he is just running a big T68 Titanium Ball bearing, and he said that there is not as much turbo lag now than there was when he had the 2 turbos.. it shouldnt be that much jus to run one big turbine.. just removing parts, and probably custom fab somethings.. i will have to look into it more..
