I couldn't find an exact match for this when I searched, so if I have missed something, please let me know. I won't be surprised if there is an exact thread on changing the mounts..
I was trying to change the engine mounts on my FG XT turbo (not a typo, its an XT!) and I was stumped on how to do it. There wasn't enough height or clearance. I couldn't get the turbo side mount out. The passenger/inlet side is easy. There just was not enough clearance to pull out the turbo side mount.
I removed all the intake plumbing, and the hot side plumbing. I undid the nuts holding the engine mounts onto the crossmember, jacked up the engine with a bit of timber under the sump, but it was still too hard to remove the turbo side mount.
What I ended up doing was to remove the passenger side mount, and then jacked up the engine under the sump again, but trying to push up the sump from the turbo side to get a little bit more clearance. There is a looped pipe connection here from the powersteering (at least in mine) and you have to undo the bolt holding it to the cross member to move it out of the way. Once that is out of the way, and you push the engine across a bit to the passenger side, you can get the mount to drop in. I used a lever to try and tilt the engine up a bit, and a second person to help would have made it easier.
Once the turbo side mount is in, the passenger mount is a piece of cake and can go in no problem.
In the end, replacing the FG engine mounts wasn't too difficult, but knowing how to approach it makes it easier.
