Fuel Pump upgrade

[GSi_PSi]

hey guys wanting to upgrade my fuel pump? just wondering what are the main
advatages of it and is it worth doing? ive got a b20vtec makign 121.5kw atw
its currently on a stock dc2 pump.

Walbro 255 + Sard fuel pressure regulator is the common choice.

Makes sure you get plenty of fuel + consistent pressure so you don't run lean, flows better.

Haven't put mine in yet but my friend did his head build before I did mine and he stated he noticed a bit more pull after upgrading his.

have been hearing alot of bad things about sard fuel pressure reg's lately (tho from tuners who are working on twin turbo v8's & xrshit turbo's). they have been saying that they hold pressure fine while your on the dyno and it's getting tuned, but after a week or so the pressure starts to drop.
after hearing this i have gone and done a bit of research as to what else is on the market and the top of the line turbosmart fpr seems to be the one to get atm.
fuel pump wise, walbro 250 intank will be enough (unless you want to go to 5L surge tank with bosch 044 external and bosch 040 intank)

u dont need a FPR, unless ur pushing out heaps of power, atleast double of the stock power... wasting money, best to stick to a fuel pump, heaps of ppl replace fpr with zero change, an only change is more problems come outta of it lol...

IF running on the track or again or the case of high horse power, than a need for a surge tank setup, with external pumps is viable, other wise, its pointless

Sorry - but a fpr works in unison with the fuel pump. Do you mean double the power or double the fuel flow ?

double power, usually that would mean a need for more fuel supply...as far as im aware, iev got mates running standard FPR on 300kw vehicles, an not one of them touch the fpr, theres not much need to mingle with the pressure, spoken to tuners as well, fpr are waste of money if the stock one does the job for a mildly tuned vehicle

Hate to say it, but 120kw is nothing, an im sure the stock fpr is more than enough to cope with it

Walbro fuel pump usually the norm upgrade.

But if there isnt wrong with the current fuel supply, no need to upgrade.

[stndrd]

but then there is always the argument of do it once, and once properly, so you have piece of mind

The fuel system should not be overlooked as a high rpm lean out could cost you your engine! But in saying that, overkill is not required.

Does anyone know the power limit of an eg fuel pump? Is the vti pump the same as the gli?

Im converting to red top H22A and only want to change the fuel pump if it cant flow enough. I want to keep the standard pump cause its quiet... :)

[stndrd]

from personal experience, once i got my b18c1 tuned my fuel pump only lasted about 4 months, but in saying that, there was no history on when the factory pump had been pulled out and replaced, or if i was the first one to change it. after changing in i put it back on the dyno & my target afr's had gone from about 12.5 i think it was to 11.5, so in otherwords, it richened it up quite dramatically. for a h22a swap, i would recommend a walbro, for the simple fact is you know it is new, you know it will be giving a constant supply all day every day, and it it will withstand the supply demanded at at high rpm/load situations

So like im running a d16a8 w/ t28 turbo in an EG with standard fuel setup.
Its been like this for years, drive it everyday.
Should i also upgrade my pump, fpr, injectors? and get a re-tune.
Any other pumps besides Walbro... they sound loud like a constant ring in your ears.

[mugen_ctr]

intake walbros aint as bad as some make out lol....theres also bosch, though im not sure they do internal ones for civics... its always best to upgrade ur pump when u turbo... tuners advice

You could do the ITR pump, but again, id rather buy a brand new, and more stronger pump for extra

Noo need to upgrade FPR..... unless ur running super power, ur b stupid to do what others say, as said the standard FPR is perfect for 9/10 mild tuned jobs, take it from me and tuners

What injectors u running? my mate maxed out his stock injectors at 2psi LOL.... so his getting it redone with prelude H22a Injectors with a 320cc rating, hopefully that should do the job

And also whats ur power ur aiming for? if ur wanting around 140kw, definate get 440cc to be safe... u dont wanna be finding out that u maxed out ur injectors on the dyno than havin 2 come back later on for a 2nd tune on new injectors, 320cc should b ok, but dont take my word for it lol.....

And when u upgrade injectors a tune is a MUST! running new injectors without a tune is asking for trouble

[hiepy]

I dont know about the OP.
But not trying to hi-jack.
I have standard injectors.
It's a D16a8 with low compression pistons, 10PSI all day.
standard rods, refreshen block/head.
I was just wondering if it's worth it, doing the pump and injectors.
Not trying to achieve big power, just want a little more power after all it's got standardish internals and its my daily.

[mugen_ctr]

Its best to upgrade both at the same time than tune... But if ur finding that ur car isnt running lean when pushing it and the a/f ratios are pretty stable throughout the rev range than no need to do it, should be ok, again its best to upgrade injectors an fuel pump for a peace of mind and for future builds or boosting more later down the track
