I have been searching for the part numbers for the 5Bar Fuel pressure regulators.
I have come across a lot of info about how a lot of the companies are crushing the 4Bar Bosch FPRs and labeling them 5Bar. A lot of people seem to think that the crushed\modified ones might not be consistent and don't think the risk of damaging our motors is worth the $100 saved in cost. I have to agree.
Wanted to get your opinions on the modified ones. What do you think?

Came across a few part numbers which are:
-B280550113/2
- 0280 B02 722-2 (Bosch motorsports order number)
- 993 110 199 80 (FVD part)
Also found an adjustable Bosch motor sports FPR which is adjustable 3.5-5 Bar; 5EUR cheaper than the Bosch motor sports 0280 B02 722-2 FPR.

Need some info from whom ever knows the actual part numbers and\or Porsche part numbers for the right 5Bar FPR. Porsche wants $240 for their FPR and I don't even know for sure that it is 5Bar ones.

Read somewhere that 5Bar FPRs used in Audis are the same and can be around $80; a lot cheaper than the Porsche FPRs.

Please provide some part numbers. Be it Porsche, Audi or Bosch ones, or for both\all.
What is the Porsche part number?
What is the Audi part number?
What is the Bosch part number?

Also something like: This Porsche part number is the blah blah Bosch part number Vice Versa.

 

b280550113/2 is the # on the 5 bar i have. i replaced it with a 3.8 and larger injectors. if you want it i can hook you up

 

That would be nice. Thanks.
I just replaced my intercoolers, my MAF sensor that was damaged, changed my plugs and found a big leak and fixed that but right after it seems like I ran out of fuel. I might have hit MAX DUTY Cycle… It could also be that my pressure regulator might have gone bad. Without hooking up a pressure gauge, etc I would like to make sure its not that. Better do that before I start changing a lot of other parts.

Are there other part numbers that are used for 5Bar FPRs?
I read Audi Bosch 5Bar FPRs are a lot cheaper and are the same thing; can be used in our cars.
