I cant comment on the rear turbo but I did the front one. simple hand tools. I pulled bumper, fans, rad/intercooler(comes out as one) then there was all kinds of room -> way easier than it sounds lol. But you may only need to pull fans. Don't over bend the flex joint on the downpipes cuz they will break.
New turbo did not have mounting brackets, updated design?. seems like alot of stress on a sheet metal manifold?
