Thanks to this thread (and particularly some of the recommended tools) MPI install was a breeze this weekend.
Only thing I can add is for cars with studs (8 bolts + 2 nuts), installing the hard line before manifold is not an option. Also, just loosening the 10mm triple square at the bottom of the support bracket was enough to depress it from the manifold stud and move it out of the way, I never had to fully remove it. Otherwise I just followed humble mechanic's video.
I have all EU parts (including hpfp with 1/8" drilled pressure regulator to the MPI rail), 925cc bosch injectors, PR harness and boost tap. Bonus shot of carbon buildup at 117k. Will be interesting to see the effect of MPI when I open it back up for cleaning sometime next year.
EDIT: found the turbo threads
