best case would be find a clean S4 w/engine problems, and swap in a S5 long block and ecu 
(or aftermarket ems)
you can probably find a S4 down south with a blown motor for cheap, won't have any rust.
I think we're going to do this with my friends TurboII that has some rust.... find a nice clean S4 NA that needs a motor .

S5's have 10% more power than S4's. And S5's just BARELY have a worst lb/hp ratio on both N/As and Turbos.
I believe part of it is heavier sound deadening, and some other miscellanious crap. Maybe carpetting. I don't remember many of the reasons why they're so heavier.
