My impression, from reading top side posts, is that you can make room under the bonnet for the Turbo. You may have to re-locate some stuff, such as the battery.
The heat transfer under the bonnet will probably be as big a hurdle as anything else. Just remember that you have some sensitive gear there.
Hope it works out for you and doesn't cause you to have to work every week-end (for double time etc.)
Gotta keep your week-ends free for runs up the country. You should be able to reach Coffs Harbour before the brakes manage to slow you down enough
Keep us posted and good luck with it, got to admit it would be awesome to see.
