As above, for a progressive system its wizards of nos or nothing, even for use in a fixed hit system though the other make solenoids are less suitable.
They will work though fundamentally.
YB's just love nitrous, I was throwing 125bhp of nitrous down the throat of my snotty old YB for ages and it just took it and took it and plenty of other people have done similar (rapid1 is another good example)
That was on a wizards of nos progressive kit though, so I wouldnt offer it as proof it will take the same power reliably from a fixed hit american kit, but it should still certainly take a decent amount, 75bhp woudlnt make me nervous at all providing its jetted correctly for mixture.
Take a couple of degrees of timing out as well to be sure, you can do this via the octane wires if you are on L8, thats what I did with mine.
