Yes you can normal summon turbo booster, but only when you haven't normal summoned in the same turn already. Rather than being a 'special summon-only' monster, Turbo Booster's special summon is a case of 'you can' do it, if you wish. Like Cyber Dragon, it is a monster who can be Normal Summoned, but has an alternate, special summon method too.

Double Summon allows you to have an extra Normal Summon. This Normal Summon is no different to your usual once-per turn Normal Summon. If you've got two monsters to tribute, then sure, you can tribute them for an 8-star monster.
