Cga fpr

[micras69]

has anyone fitted a uprated fuel pressure regulator like the FSE/sard style to the CGA fuel rail? and for that matter do they fit?

would be a grate help if anyone can post some pics of the CGA FPR, standard or uprated will do

cheers

the stock CGA ones are held in with a clip eh martin, so you would need a purpose built fitting (or else a blanking fitting, and fit the fpr in series on the return pipe)
i squashed the top down on a stock one years ago to raise the reg from about 35 psi to about 50 psi, but our CG,s need a rising rate type one really (higher ratio) so that we can use bigger injectors without the overfuelling problems at low throttle (high vacuum)

Ahhhh blooming hell man, why isn't anything easy for me grr. So what you saying frank, blank the FPR that's on there and fit my sard FPR to the fuel inlet on the rail?

you need to fit it on the return pipe martin

might be worth asking james (Nis) what he has done with his fpr and whether he is just running the stock one.

 

[frank]

if you remove the white "O" ring the fuel will bleed through the stock fpr and then will be regulated by your sard fpr when fitted downstream (attached to the return pipe)

Ah right I thought it was put on the inlet side frank, cheers bud (Y)

good idea Ed although James in never around so it might be worth asking other ED

good idea frank!! simple but effective, my only worry would be that that might restric the flow?? i suppose you would soon realise if you couldnt drop the pressure enough

make sure you messure the pressure before the oe fpr just incase it does restric the flow

ANOTHER edit. you could always completely remove the yellow niple, that would free up flow all good

id doesnt look like james uses a fpr. surely if the injectors and fuel pump is big enough and its mapped correctly then the standard fuel pressure is fine??

 

[micras69]

Well I've just payed £150 for a genuine ltd edition sard FPR so I'm going to use it!

 

[Stani1029]

i paid loads for a sard one too and it wouldnt bloody seal properly. just kept leaking fuel and the car wouldnt run at all on it.

 

[frank]

if you could get a fpr with about a 4:1 ratio (like what the methanol guys use i believe) that dropped the high vacuum/idle pressure down to about 1.5 bar (instead of the stock 2.5) but retains the stock 3 bar low vacuum/WOT pressure, then the 1.6 GA injectors might run sweet with our N/A mods (ie, without the overfuelling at low revs, and without the stock injector underfuelling at mid/high revs )

Stani are you shure it was a genuine sard product? As there I loads of Copys and also copys aproved by sard but not made by them have a look around the FPR for resessed dots, 0 dots means it's a total fake, 1 means a copy approved by sard bit not as good quality as there own, 2 means it's a genuine product made by sard

If you carnt find them I can send pics

 

[Noddie]

would like to see pics for future ref mate

 

[Stani1029]

martin ive sold it and it was very good quality, not bothered by it like.

 

[micras69]

oh well stani, mine had a problem with the threads but thats nothing realy

these are the pics of the sard "dots"

 

[Stani1029]

id never have noticed the dots, its not something i looked for. mines was exactly like your one. same box too

 

[micras69]

i only found out when i was looking to buy one and it came up in the rx-7 forum about the dots
