fuel regulator - 4bar

[Aditi]

in which Gasoline engines models the the fuel regulator is up to 4 bar Pressure ?

the c20xe engine (dizyyless with motronic M2.8) - The fuel pressure regulator of this engine is the Bosch 0 280 160 703, that have 3.0bar.
The first generation of c20xe is 2.5bar pressure regulator.

What about the omega. Someone know ?

Good to know, Just like that
There is any regulator That came with the engine as a standard ?

not sure on the style os fpr on the xe, but bosch motorsport make 1 that fits the later style and is adjustable. not cheap but.
if it's the same as the late model style, the xr6 turbo is a bosch 4 bar.

The c series engine pressure regulator is different from the later ones. Gema make a an adjustble one but not cheap, I just bought an adaptor plate of eBay then you can use any aftermarket fuel pressure regulator you like.

z22se runs standard with a 4bar pressure regulator.

if you were going for the courtenay one I'd recommend checking out ebay first though - you can often get them for around 30d

Which adaptor did you buy???

Just a tx autosport one nothing special but does the job. Don't forget the C series engine has a different pressure regulator setup to the Z series engine.

although the c20/22sel is the same as the zlet ;). and the zxe is fpr at back.
dont think you can class just as c and z unfortunately.

[Jerram]

by the way - which fpr would be better for the c25xe - with GSi cams and standard injectors, 3.8 or 4bar?

[auzvectra]

from what i hear the 3.8bar 1 is best for the 2.5L. but the 4bar wouldnt hurt.

are u all getting re tuned after u change ur fuel regs?

no need for retune as far as I know. Interesting fact is that they use an original fpr and press a large ballbearing onto the top so it dents a bit creating a higher pressure (so I was told by a mechanic in Holland..............)
