01-07 Subaru WRX STi 550cc 555cc EJ25 Fuel Injectors :eBay Motors (item 190347531173 end time Dec-06-09 18:54:50 PST)

 

id say yes, but here are a new set:-

4# 93-99 Subaru 550cc INJECTORS EJ25, EJ20 STi,WRX

these are what i'm looking at mate

 

just a little pricey for know, need to find a cheaper set.

 

works out to about £176 , so probaly looking at £200 with postage from USA . there was some in the for sale forum for £150 the other day ,

think i might get mine from the above link , at least you know with them theyr'e brand new , cheers

 

think i might join you in purchasing them

anyone got feedback on these?

 

yes, venom injectors. been snooping around the net.
lots of persons have said these fail & are wrongly flow checked coursing engine damage.

i seen them before i looked into it.
the other option, is the blue 500cc sti v5/6 injectors
i'm only after around 330/340bhp. the 440cc one will get there, but will max out more reaching it.

 

didnt realise they were venom, yeah a lot of negative feedback on them,

i will now not be buying these.

is the v5/6 direct replacemnet?

i too am only aiming for 330ish,is there an other alternative for me?

 

are the ones in your link venom injectors , or do you mean the one's in for sale forum , cheers

 

the 440cc injectors i have will get this.
but will max out more compaired to 500cc ones

regards to the 500cc sti ones, i'm sure there phase 1.5
but if phase 2, only takes a fitting kit. i have phase 2 in my early classic, phase 2 injectors have a better spray than phase 1/1.5

so being standard on the sti v5/6 will be stable on tick over
well thats the way i see it.

been looking up injector info all day, its amazing what you find out when digging on the net

 

the ones in the for sale section.
hope the guy isn't to disapointed.
did a check to see what these venom injectors are like. nearly every thing i read, says there rubish and can damage your engine one power increse
once brought, they need flow checking & setting up

heres one of the sites:-

theres many more saying the same too

 

what about these , any good?

4 - Subaru Side Feed 500cc Fuel Injectors - NEW:eBay Motors (item 280418713746 end time Dec-03-09 10:08:40 PST)

 

i did see them, the thing is. the casings are for 380cc ones
so im thinking these are modded ones.

proper subaru 500cc injectors are blue.
theres a set of yellow 550cc injectors on flee-bay too
but always throught the yellow was 440cc????

i've looked every where on the net. & theres lots of colours for the same cc
there must be somewhere that knows whats what

 

this is another for instance why i desided against then pinky things
the link they were 550cc yes???

4# Subaru 93-99 800cc Fuel Injectors EJ25 EJ20 STi,WRX :eBay Motors (item 130336155575 end time Nov-08-09 03:56:07 PST)

same company. know ther 800cc???
with the same casings. there just modding standard injectors
some seem to work, most start playing up

 

Just get your own injectors modified. Saves all the faffing around and being confused about which ones to buy etc etc... Once modified and they have brand new pintles fitted, flow matched and cleaned thoroughly to be as good as new. Then they're flow tested to see how they perform and bob's your mothers brother!!

Subaru already provide you with a decent bit of kit that just needs altering to up performance so why sweat it?? Same with lots of other aspects of Subaru's.

P.S. dabow....most don't start playing up if they're done properly by a reputable firm!! It's much more likely if you modify them yourself that they start playing up, and often do because you haven't modified them properly!!

 

i have been toying on this one,
after all, i have 440cc phase 2 injectors
only really need 500/550cc ones

to keep my potions open, may check this guy bob out
does he have a site mate

if so, do you have a link at all mate
if its pricey, i'm looking for the blue 500cc ones

 

who does this?

it sounds like the best bet

 

i can not find any links for this bob as yet????
but i'll look into it to see whats the best option
+ whats best to map at the end of the day, i'm using the esl live map board. so need to check every option thats best suited

any info is good in this modding came

 

why not fit an adjustable fuel pressure regulator and guage??
If ya nearly there on 440 s just up the fuel pressure and map accordingly

 

i have a fse boost valve, infact i have 2. brought the standard type, then seen the newer one which i sprayed red to match the car. but heard 440cc injectors max out still
thus needing replacing as they wareout quicker

dont want to chance starving the engine if it did happen

 

Mark @ Lateral performance, I have a set with him now being done

 

A set of 440's after modifying should flow around 700cc and 550's after modifying 800cc or thereabouts. The toughest job when modifying injectors is to make sure all 4 are flow matched to at least within 1-2% of eachother, that's the real skill.

RA Dunk - If you don't mind me asking, how much is it costing you to have them done? BTW...I don't think your injectors could be in better hands than Lateral Performance.

 

Im not too sure on price yet, I suspect one of them's sticking open and as long as they are down Mark is going to see if they can be increased to flow more
