Pretty much, all manual boosters are the same. It's nothing more than a valve that opens and closes an orifice as you turn the knob.
If you have an old aircompressor sitting around, you can use the pressure regulator as a MBC. Its a great piece to use as an MBC.
IN fact, HKS use to use an aircompressor regulator and stick there HKS logo on it and charge big bucks for it.
So its safe to say that 95% of the MBC out there are all the same.
