u dont necessarily need different floats, u just need to supply the bowls with the same boost as your putting down the throats, for example on my twin sidedraught turbo setup, theres a breather on the bowls where the throats are , on the airbox ive made i just put a hole in it so the same boost is going in the breather. im not entirely sure but other than that u just have to do the obvious and just seal everything properly.
