...2.5 bar (36psi). Only the 325i uses a 3.0 bar (44psi) regulator. The 318 M10 uses the same FPR as the E30 M3, which is also 3.0 bar.
88 ///M3 Cinnabar

Apparently, the fuel pressure regulator from a 84-91 325 will fit on an M10 engine. Anyone know the difference in pressure for a stock M10 vs the unit for the 325 engine ?

Also, anyone put a air flow meter and throttle body from the 325 or other donor car on a M10 ?

Two main goals here, get more air into the engine and boost the fuel available to burn with the increased air flow.

Other suggestions, short of swapping engines ?
