I have no idea if my logic will work in that way... if nothing else it will provide a taller 1st gear which will be handy with 260 bhp (hopefully!( yes my power goal went up)
And higher top end... although i dont think i will be doing 130mph any time soon !
So to answer you question in short. Yes i hope mpg will improve as well as lower engine noise, and yes i have other reasons ! Haha
I havent started a thread yet on the Project car, im waiting until all of my preliminary work is done, when im actually putting bits together rather than number crunching and finding bloody part numbers for 12mm VE Pumps !!!
It will come soon enough though. Its definitely happening. The turbo is here and my control system is (in my head at least) about sorted 
Cheers !

Sorry, thought I'd replied earlier
Yes, my experiences are with a standard engine (including turbo) and M46 gearbox. So perhaps not so relevant - I'd not considered that
260bhp from a D24T would be awesome, I'm looking forward to seeing this happen
Please do post details of the turbo change and control
