fuel pressure regulator

[moshik1958]

hi
my car is e23
i replaced my engine from 2.8 to 3.0
i kept the L tronic ( ecu ,intake injector etc..)
probably i need a more fuel to the bigger engine.
the original fuel pressure regulator is 2.5 bar.
it is a good idea to replaced it with 3.0 bar regulator?
thx

No, the AFM tells the ECU how much to inject based on how much air is flowing. So it automatically compensates. On US L jet cars in 79-81 they used the exact same parts on 2.8 and 3.3 cars. Same injector, same ECU, same AFM.

Not sure what year you have, I picked one at random, but here's a listing of what a particular injector fits, that came on a 2.8 E23.
