Well, at this moment, I am investigating the Harmonic Drive. Something like this:
http://harmonicdrive.de/de/produkte/einb...uc-2a.html
This will allow full 360 degrees of phasing, BUT I would like to modify it such that it will have a safety function if the electric motor fails.
About the pressure:
Althoug I also think that 250 bar is more than enough cylinder pressure, we still do not know what exactly happens in the pre chamber. I believe, there happens magical stuff, with decomposing indecomposable, compressing in-compressible and so on ..
I mean, there must be a reason that these boat engines can run almost 7k RPM 
What I mean is: to have 250 bar in the cylinder, there must be a X-factor higher pressure in the pre-chamber. And that pressure in the prechamber will be the back-pressure for the injector .. and (back pressure + 150 bar pop-open pressure + pressure Y to sustain certain flow) = the pressure that the pump will have to deliver.
I by the way found out that there are piezo-sensors. Their response time is measured in micro-seconds. That could be the solution !

But indeed, if you say that it is including preinjections, then there is also a small portion of time where the injector is closed.
