The msd blaster 2 is massively more powerful than the group a, the msd in this case is nothing to do with msd in blackpool, as you've guessed, I know people who have used the msd blaster 2, to excellent effect, it's a VERY powerful coil, the group a is just a std fit coil on a lancia, but was more powerful than the crap they fitted to the cossie when new, so is still a good upgrade.
