|You can remove the sub frame entirely or drop it down a bit as per FSM. I replaced the oil pan seal in my TT with it removed entirely and would recommend you plan to remove it, once its down you'll see how hard it is to do.
Without a plenum to tie straps/chains around be careful with where ever you find a place to support the engine using an engine support part. Its near 400 pounds (~181kg) dangling over your head.
I ran grade 8 bolts through the upper plenum brackets on the side. I've seen people put chains around the intake runners too.
