Default What Dodge is the 4Bar FPR from?

Hey guys, I'm looking to pick up a 4bar fuel pressure regulator for my 92' 940T. From what I remember, there is a 4bar that came from a Dodge turbo car that fit without any / minimal modification. I thought that I had saved that information but, of course, when I need it I can't find it.

Can someone please give me the year, make, and model if they have the information?

FWIW: I have search the 'how to +T your car' sticky for at least 3 pages and can't find it there or with other forum searches.

Thanks!

BTW: My FPR was leaking, so I swapped it over with a spare I had lying around. I figure that there is no sense in buying a stock 3bar, when I can get a 4bar for probably the same price and have one less thing I need to get for when I am ready to add a manual boost controller.

is there some reason you want to put an increased strain on your probably 26 year old fuel system to possibly get a minimal amount of additional fuel?

Might investigate getting bigger injectors vs. the uprated FPR....YMMV

"4 bar FPR found on older turbo I turbo dodges w/ the newer style intake manifold (that draw throw but blow through like ours). bosch part # 280 160 260. mopar # 4306015 437. these bolt right into the volvo rail and will need a 1/4 fuel line to go from the return line on the FPR to the tank. this is a little smaller than the stock return line. this is a 4 bar FPR ... takes fuel pressure up to 55psi."

Actually, that doesn’t look like it would bolt up right.

You fail at eBay.

This is the one.

FYI,
I put on a Volvo 3 bar regulator in my Turbo Dodge to lower my fuel pressure so I can have more fuel volume.

Add wideband to your list would be more beneficial.

An engine needs the correct amount of fuel. Not more, definitely not less.

A wideband will help monitor air fuel ratio while a higher fuel pressure regulator will just allow more fuel flow thru the injectors making the engine run rich, especially at WOT (open loop). Un-burn fuel will get into the oil and eventually wipe out the engine bearings.

Running more fuel than needed = BAD.

Have a wideband already, see 16v turbo project details in my sig.

Future mods must support more for more! 42lb delphis with a 4bar regulator should comfortably get me enough fuel for 300+ hp.

Why not just get the correct injectors?

42lbs injectors are tiny and wouldn't give you any head room.

I thought I had enough fuel with 75lbs injectors, only to find out I was running out of duty cycle using E54 and 25psi, then I had to buy bigger 96lbs injectors. Well, guess what, my 96lbs injectors will be at their limits using E82 and 29psi.


Sell those 42 lbs and get some big injectors instead of spending money on a fuel regulator.
