    318ti s52 swap question

    Hey guys just have a quick question. The 318ti that I'm using has the fuel pressure regulator under the car by the fuel filter instead of it being integrated into the front of the fuel rail . It is an obd2 m44. Does this mean that I don't have to use an FPR from an s52 and just hook up my s52 fuel lines to the 318ti's FPR and be good to go ? Thanks !

    I think the 318ti FPR is 3.0 bar and the s52 is 3.5 bar...just going off memory. I know they are different, so I decided to run the s52 FPR.

    Its an easy swap, just buy or take from your donor and pop the s52 FPR in.

    What was the solution? Did you end up needing the 3.5 FPR?
