Fuel pressure regulator

[Vladi]

The M42's got a 3Bar FPR. Would a 325i M50 3.5Bar regulator help in any way? What's your oppinion? Thanks!:D

[Vladi]

You want a 1.8t VW/Audi regulator, some had 3.8 and others had 4.0 bar and fit our rails.

what years fit our car? do they go year to year or can any 1.8t fpr fit? do fprs and high pressure fuel pumps require standalone tuning?

i would like to know this as well. also maybe even what cars came with lower pressure fprs. I dont know what my engine is going to do when i start it up with the 24's

Best thing is to get an AFR meter and this way you see what's going on and how much you can play with the software. :rolleyes:
