From Porsche PET:

944 110 198 03 = Bosch # 0 280 160 227 = 2.5bar for ’86 to early ’89 Turbo

944 110 198 05 = Bosch # 0 280 160 286 = 2.5bar for ’89 – ’91 Turbo

My ’89 uses the early regulator with the barbed fuel line fitting. Later regulators have a threaded pressure fitting.

In general, the 3bar regulator is used with higher than stock boost.

Check Clarks Garage for more specifics.

I have a 1987 924S and happen to have a spare NOS FPR which is Bosch # 0 280 160 263. It looks like it will fit the 924S but the original part is 0 280 160 227. As I understand this thread, the original on the car is a 2.5 Bar unit and this potential replacement is a 3.5 bar unit.

Will I do any harm if I introduce this? I'd just like to make use of spares I have

Thanks!

If you use the 3.8 were it calls for a 2.5 you'll need to put koolaid in your radiator and fill your gas tank with a 50/50 mix of Cuervo Gold and Gumout. ~

I actually think my SPARE is the correct part. I think the 1987 924S was supposed to have the 3.5 bar unit. These three sites seem to show the Porsche part # which translates to 944.110.198.03 or 05....

Seeing that the FPR is now in the stratosphere price wise. I think I'll use my spare.

Complain really REALLY loudly if you disagree

I just replaced the FPR in my 924S and the rating is 2.5 bar. But I'm curious to hear how a higher pressure FPR works on your '24. So if 3.8 Bars = 55.1143404399999923 Psi and
2.5 Bars = 36.2594345 Psi
and the FPR is vaccum operated,
would the higher rated FPR need more vaccum to operate it correctly?
