Schumacher usually shows where the engine should be located, i.e. it's factory location. I would confirm that first, then if you can move and/or shim things about till all clears. But it is not uncommon, even with TTI's to occasionally need to manually clearance the tubes (bash a dent in them). If you decide you need to go that route I'd look at how some do it with finesse, You tube video or similar.
