Im not aiming to reduce the running pressure of the cr system, just to increase its capacity for flow. Excluding issues with sourcing info, injectors themselves are fairly easy to upgrade, or at least the nozzles are. Pumps, however...
We are restricted in pump choices because the only gen 1 pumps that fit these engines without serious mods is an r70, our standard pumps are r65, so that's not much of an upgrade. That leaves two choices: mod the pump for more flow or completely rebild one to a custom spec. I may well be wrong, but to me the former looks the easier option. If we're going to rebuild a pump we may as well go straight for a 2k bar gen 3 pump with gen 1 controls and run as much rail pressure as we like, do you see what i'm getting at?
And I see your point about the bmw engines, but i'm more interested in seeing what I can do with what we've got. Besides, if I was going to have a bmw engine i'd keep it in the bmw, rwd ftw.
