S60R Turbo Upgrade

Hey,
Has anybody tried doing a turbo upgrade for the S60R? I'm interested to see what kind of performance an upgraded turbo would do for it, and what the price would be....With an upgraded turbo, what else do you guys think would have to be modified for the upgraded power? How much work goes into turbo upgrades...is it just a swap in swap out? Thanks a lot

you can check out www.svenskeracing.com. They also help host swedespeed.com... cool sites. they have a stage 2 turbo upgrade... i guess they replace the k 24 internals
