to keep the sleeper you would have to do a number of tricks...
shorten all the half shafts and the longitudinal axle as needed to get the drive train smaller
to go sans flares, tub the openings and/or cut the body in half to widen the whole car...
a lot of times whole drivetrain conversions are done by cutting the complete upper structure off of the donor car, leaving just the floor pan, then welding the 'desired body' onto whats left.
an old master of mine always said, "if you can build a box, you can build a car..."
as it is I just need to get my econo box on the road. hope to get my block /crank back from the machine shop today, head and clutch are in the mail, i'm welding up my seats brackets and finishing my 'race weight' dash this weekend

Ever looked under the hood of an Evolution Lancer my friend? It's pretty tightly packed AND the Evo chassis is several inches wider than a standard Lancer chassis, which is also several inches wider than a Swift.
There are also limitations as to how much you can shorten half shafts, etc. on a front wheel drive car - you have to allow for those wheels to turn L/R in order to be able to steer
I've never seriously considered it, but my Swift is usually parked alongside the wife's Lancer when it's at home so I have a pretty good idea what the differences in width are, and I've parked her car alongside the Evo in the showroom where she works (a Mitsubishi dealership) often enough to notice the difference in width there also - the only way you're going to get an Evo drive train into the front of a Swift is to cut it and widen it, I'd recon on a good twelve inches or so - and when you're through that, like I said, it's going to be that obvious, that you're no longer driving a sleeper.
