As explained previously in this thread, and by pm:
You will struggle to find a cp1 pump that can handle producing 1800bar on a regular basis, obviously they are not designed for this and the resulting increased stress will reduce the pumps life considerably. The R70 pumps people are using are not designed for this pressure either, both are rated to 1500bar only, however the R70 is more likely to be able to keep up with the injected volume required at high rpms, hence it's popularity as an upgrade.
Beyond that your only real option is to have a custom pump made, then you're talking serious money. Or learn to modify them yourself, from experience i wish you the best of luck getting the information required for that kind of modding, less accessible than mapping by a long shot...

Ideally you need to combine it with a R70 pump or better, as the standard items are not designed to generate that kind of fuel pressure and may well struggle to maintain flow at higher rpms/loads.
