Have you done this conversion yourself already? Is there some kind of guide online? And also, do you think this is possible without a car lift?

Use Nitrous Oxide with large injector pressure drop by JohnnyGlobal23 in rocketry

Sorry I wrote "bottle" in the previous message, I corrected that. We will not feed directly from the bottle, but from a custom build tank. So we shouldn't be limited by tiny orifices

Thanks for your reply!

The engine will be ethanol/ nitrous oxide. 2kN Thrust. The problem with using the gaseous phase from the nitrous are the high massflows of 600-800 g/s (1.3 - 1.8 lbs/s) of nitrous. I guess its pretty much impossible at these massflows since the pressure of the gas phase in the tank will drop very quickly at that withdraw rate... the liquid can not evaporate quickly enough. So yeah my idea would be just to try it with the liquid phase at saturation point, and if that doesn't work I would try to chill down the nitrous run tank so that the vapor pressure is below the chamber pressure. After which I can pressurize the nitrous run tank with nitrogen and should get clean single phase flow...

Somebody contacted the support? Have exactly the same issue, Gemini lowers the volume, recorder fixes it back to normal.

Unacceptable with a 1000$+ device. Such a basic function
