leave the turbo attached to the manifold, you dont have to lift it all up just across toward the strut. i did this a couple of weekends ago with no real dramas, other than i couldnt get the thing out but that cos its a hks setup which hits the chassis rails
ive heard as little as 2hrs for the job so i reckon you could do it yourself, its just a matter of unbolting and being methodical so you dont lose anything or drop any bolts into the manifold!
