Well i took the plunge and ventured to a new company for injectors, one i haven't seen anything on the forums about..
They are from a company called Fiveomotorsport http://www.fiveomotorsport.com/
They make top feed sets in 555cc, 650cc, 850cc, and the ones i got, 1000cc.
http://www.fiveomotorsport.com/Injector_SetsSUBARU.asp

They are described as this from the site:

"Modified Top Feed and Side Feed fuel injectors 560cc - 1000cc
The fuel injectors listed below are all BRAND NEW Denso fuel injectors that are custom manufactured and flow-matched into sets.
Set pricing ranges from $---.-- for the top-feed 560cc to $---.-- for the side-feed 570cc Yellow Tops.
Use for super street or racing 4 cylinder, single or multi-valve, normally aspirated or forced-air induction (turbocharged) engine applications like the Subaru 2.0L 4 cylinder. All are high performance, high volume fuel injectors for modified engines only. Stock ECU can be used. (See listings below for OEM replacement parts).

Custom Milled Denso Top-Feed:
High flow fuel delivery is from a multi-hole disc that delivers a medium-wide cone-shape spray pattern for maximum efficient fuel atomization.
High resistance, no inline resistors or resistor box required for use.
All of our Denso custom manufactured injectors will function at rail pressures in excess of 88lbs/hr, 6 bar. Will maintain linearity within 1%.
Excellent low pulse width response with predictable response down to 2ms.
Excellent atomization for modern multi-valve engines.
These sets will require no more than a 1% trim for easy tuning."

The 555cc and 650cc injectors have a orange Denso shell, while the 850cc and 1000cc injectors use a white Denso shell.

Now to see what we got..

NEW!! Injectors back from flowtesting..

http://i104.photobucket.com/albums/m195/twiztidunreal/Motor%20number%204/Motor4039.jpg
They said they were not all exactly 1000cc, but all with in +7cc, with 1002cc being the lowest

I was told the spray pattern was the same as modded stock injectors they have tested.. not the greatest.. but usable

reserved for more

"High flow fuel delivery is from a multi-hole disc "

Doesn't look like a multi-hole disc to me?

Unfortunately, not only is having 3 injectors that flow exactly 1000cc unlikely, it's damn near impossible. Makes you wonder what the accuracy of their testing equipment is.

"Excellent low pulse width response with predictable response down to 2ms."

Ask them how they measure this or where they got this statement... :rolleyes:

yeah i noticed there is only one hole on the bottom as well, it almost looks like a ball point pen..

i will have then all flow tested by another place and see what all comes up..

i would have loved to get a set of 1000cc from you guess, but couldnt afford the extra $100 or so in taxes since im in Texas as well...

You are still using the oem fuel rails? Did you at least reroute the fuel lines in parallel?

You are still using the oem fuel rails? Did you at least reroute the fuel lines in parallel?

yes stock wrx rails, 2 driver side rails paralleled with adjustable FPR

ahh ok nice that should work fine then

just got a response back from Bruce at Five0, this is what he had to say..
"
Thomas – I am sorry about the statement of multi-hole. With these new sets we have changed to this single ball-type modified disc for even more efficient fuel atomization.

The 2ms is the open time.

The Bosch “Black” set is a modified 0280158117 53lb fuel injector specially custom milled to flow 1000cc/min at 3.5 bar.
"

the Bosh black set he is talking about are ones they sell that look just like the ones Tony up there sells but with out the color rings on them

i will still be taking them for flow testing to make sure their accuracy

2ms open time? Does that mean 2ms dead time? At what voltage?

I like the way they package their injectors, kinda neat. I might try that.

newest response
"yes dead time, I don't know the exact voltage.

The injectors are drilled then flowed and the data from each injector recorded. We then match them up. Some are 1002, 1003, etc. as you say but others flow exactly 1000 also."

i am taking them here in a few mins to get flowed, so we will see
also, the numbers on them aren't all in order either so they could just put together sets that match out of many injectors

I'm interested to see the flow. I can assure you that 2ms is WAY off from the correct dead time...

Does that injector actually say Denso on it? It looks like a Nippon Injector. Nippon Injector Corporation is a Japanese company partially owned by Bosch

I'm interested to see the flow. I can assure you that 2ms is WAY off from the correct dead time...


I don't know man, they are 14 ohm! :eek:

I'm very anxious to see what the results of these are. Not only is the low price of these a huge plus the fact that they come with a 3 year warranty is awesome I think.

haha wait till you get these bad boys and there is a 2 hour surcharge on your tuning bill because it took your tuner 2 extra hours to figure them out. Then wait for your piss-poor idle and horrible partial throttle drivablility.

They will warranty DEFECTS for 3 years - Not ****ty injectors..

Go to HT and search some of these you will find very negative results.

HT=Hondatech.com..

-Jerod

what about their bosch 1000cc injectors on the middle of that page?
http://www.fiveomotorsport.com/Injector_SetsSUBARU.asp

That's a great price, but I wonder what kind of spray pattern they have. I may email them for more pics.

Haha, hope you don't get that set, they're machined totally wrong and will never seal in a fuel rail. There's nothing for the oring to seat against. lol

http://www.fiveomotorsport.com/PartsJPEGs/Injectors/Milled_Custom%20Injector/0280158117_4Subaru.jpg

The description says multi hole disk, just as the description of the original injectors in this post. I'll bet money that's a "mistake" as well....

http://www.fiveomotorsport.com/PartsJPEGs/Injectors/Milled_Custom%20Injector/0280158117_4Subaru.jpg



YIKES :eek::eek:
look at that! two orings is so ghetto...

well i get them back tomorrow so we will at least see what they flow..
my tune with them won't be for another few weeks or so

Same length..

your o-rings look good. I doubt you'll have sealing issues. I was commenting on the black injectors that Tony1 posted a picture of.

updated in post 3 with injector flow test results..

lol, why would they print test results with incorrect data?

I'm sure you're ready to install them, but if you're interested in getting truly accurate results, i'll test them for free. PM me if you're interested.

I'm sure some will think that the results will be skewed because i'm probably biased, but I can promise you that is not the case.

There is a ton of incorrect information floating around and also A LOT of injector companies using testing equipment with very little accuracy or consistency.

I honestly think we have the most accurate testing and pairing in the industry, yet even on big batches of injectors, we rarely see +- .5% which is what they are claiming you have. Hence my assumption that the testing equipment is inaccurate. The thing is, if you can't measure accurately, it makes your results look that much better.

I think I will stick with my Awesome Bosch injectors from Tony. I would rather spend the extra $200 knowing that I have a good set of injectors.

The Bosch/ID injectors from Tony (or wlel I got them from xenocron) are by far the best 1000cc injectors Ive ever tuned for.

M@

I think I will stick with my Awesome Bosch injectors from Tony. I would rather spend the extra $200 knowing that I have a good set of injectors.

well for me, it was more then an extra $200, it was an extra $200, +shipping which was like $20+, +Tax which was another $40 or so, it was more like $525 for the bosh.. for me that was almost an extra 300, and over double what i paid.. for what i got, they are the same spray as modded stock injectors, and many people use those all day every day..

as i said before, i would love to of had the bosh, if it wasnt twice the price.. but i guess we will see when the tune comes...

well i know when i modded 2 sets of injectors to get mine, out of 8, i got 2 sets that in which, each injector flowed with in 1% of each other..
one set was 785cc range +/- 5cc and the others were 828cc +/-8cc

now if i could get 2 sets out of 8 that were that close.. i am sure they can get sets alot closer when they are doing 50+ at a time and more then one set at a time

No worries, hope they work out well for you.

As far as our charges, shipping is generally $10 or so in TX and tax is 8.25%, so about $38. Your posts make it seem like the tax is $80.

4 injectors - $460
shipping - $14 regular or $19 priority
tax - $38
ttl - $517

vs the total shipped i paid was $255..

im not trying to talk mess about your injectors, im just being a guinne pig for the NASIOC community to see if i can find us a set of cheaper injectors for those on a budget build..

Nothing wrong with that. Somebody has to try things. :)

Results?

Did your tune cost you several hundred dollars extra because of the injectors?

Have a video of the car idling with these?

Is engine damage and drive ability of your $20k car worth $200?

haha

wow, what an ass....
any ways, no i have not had time yet, i am going to try to get it running this week..
and no, my tuner charges per tune, not per hour, to get it right....

Yea I'm a dick head. Complete *******. But you have no idea what your getting into. I'm trying to beat it into your damn head that your car will idle and run like ****.

That sucks for your tuner because his $ per hour will go down greatly while trying to sort these out.

I've tuned enough Honda's to know how ****ty injectors make things suck badly. Especially driveability.

how will these run any worse then cut top modded stock injectors?

They sucked horribly. Hence my journey to find decent injectors.

They idled like crap, had constant misfires. Dead spots. Lean/rich spots that when tuned out would come back as opposite from day to day temp to temp.

Modded stockers suck. Not having latency's suck. Having a knock off injector that isn't done right sucks.

You get what you pay for with injectors. And when these suck and you call for help they are going to tell you sorry. Tony would help you out or refund you if your not happy.

hello A$$hole did you not read his post????

"im not trying to talk mess about your injectors, im just being a guinne pig for the NASIOC community to see if i can find us a set of cheaper injectors for those on a budget build.."

leave him the **** alone and show his results. you really don't need to get on a mans case for going out and trying something new. If it fails oh the **** well its his god damn money. I really don't see why you are getting so upset about it. Chill out and stop being an ass.

How about get on Hondatech and read about the guinee pigs on there.

You will change your mind...

I'm trying to save the kid time and money.

Yea I'm an *******, your not shining light on anything new.


-jerod

lol Jerod, Tony can always count on you to attack anyone who considers other 1000cc injectors. Your blind devotion is unrivalled on NASIOC :)

Any decent tuner should be able to get the correct injector settings sorted pretty quickly - arguably quicker then the bosch injectors anyhoo ;)

i also ordered a pair of these injectors and they were complete garbage. customer service was horrible. full review of these injectors will be coming. not happy at all.

what happened with them? i was told they had a bad spray pattern, but not horrible.. what went wrong with yours?

started the car today, runs fine, sounds nice, but i have an oil leak i have to pull the motor again to fix, so i will be a bit before i can get to my tuner

what happened with them? i was told they had a bad spray pattern, but not horrible.. what went wrong with yours?

first of all i spoke with whomever on the phone for a LONG time and he said they were plug and play. they are def not. my builder resodered everything and than when we run them they run like dog ****. idle is horrible, misfires everywhere, bad spray pattern. i called 50 up and told them this. they said my tuner was not capable of doing the install. that really got me fired up. the only way to get these things to run was to tell the ecu they were the flowrate of like 3000cc lol. the injectors were like garden hoses going into the engine. i call them up again and he said o wait they didnt come with adapters? that got me even more crazy. i left numerous messages and so did my builder. i filed a claim against them with my cc. ive dealt with numberous companies and this is the only bad one i have dealt with. they are a serious fail in my book.

hmmm.. mine were plug and play, i didnt use any adapter, factory clips slid right on(check pics in thread).. idle fine, no misfire yet.. and they are scaled at 500cc right now for my brake in..
i had them flowtested as you might have seen in this thread, but they were all 1000cc, just the spray was as bad as modded stockers they said

maybe they made some revisions?!? when did you order/recieve yours? i got mine about a month ago or so.. well when ever i started this thread, lol

why would you scale 1000cc injectors at 500cc's for a break in. That doesn't make any sense unless you have a oversized MAF housing. Regardless of that, break in should have NOTHING to do with altering your scaling.

Not exactly I've actually been recommending another vendors to people lately. Yea that is true. I just did about 5 min ago actually. :)

The point is, I've read about these on H-T and a few have had some serious issues with these. Tunes that cost them 2-3x what it should have because of the time needed to get the injectors/fueling dialed in.

In my honest opinion injectors can be and ARE the most important part of a build. As your engine wont run without fuel. And a good spray pattern and a reliable, fire to fire injector is going to produce a more reliable and easily driven car.

Any Nasioc vendors that offer injectors and Bosch's are 100x better than these in every way. Yes, even DW's. I actually have become a bit fond of some of the DW injectors. I helped a couple of guys with DW's and they actually seemed to be nice injectors.

These are just plain rotten end of story.

I'm sorry OP, but there is a reason why builders/tuners recommend certian injectors and you will NEVER hear of a reputable tuner/builder recommending these injectors.

I don't think its blind devotion, Tony's reputation speaks for itself, its just that he is new to Subaru's. I actually have enjoyed over the years to watch people try to slam or discredit him, only to lose every time... so to those who keep me entertained, thank you.
Everyone can beleive what they want to beleive, but so many of us have already learned, If he has advice about something, take it, and your car (and wallet in the long run) will thank you for it.

got er ideling, now to get my exhaust flange changed so i can hook the DP up to the catback, brake er in, and get an inspection, lol...
then the tune comes...

So, yai or nai on these injectors?

So, yai or nai on these injectors?

i have not got a tune yet... i can take some latency logs and a few other thing on my daily drives will i await my tune.. i haven't had any issues yet

well, 1300 miles so far, no issues, tune comes in one week.. then i will post results and maybe get my tuner to post in here about how he felt tuning them..
Thanks for your patience

any update on these injectors?

5000 miles so far but I haven't got tuned yet.... Had an alternator to replace and still a cv boot before I can make the drive to get tuned

soooo.. ummmmm 2010.. and no updates.. did u get tuned??

Updates please?

They sucked, and he bought the injectors he should have bought in the first place.

That is my prediction, at least :)

nope, still untuned, lol
over 10k on the injectors.. still no problems so far..
hope to replace the turbo and get a tune in the next few months, but i've hoped that for months now...

i checked out all the stuff over on the honda-tech forums on these, and the worst thing said was that someone received the wrong injectors. This was immediately corrected at no cost to the buyer. I also found quite a few people on RX7club.com and some of the domestic forums running these. It is basically the same story over there...no problems with the injectors, just a few cases of receiving the wrong injectors. The 3 cases i found of the people receiving the wrong parts were all corrected by the company pretty quick. They covered all costs of shipping the new injectors as well as returning the old ones (not that shipping injectors is expensive, but its the principle of it). One of the guys on RX7club has been using their injectors for a couple years now with no issues whatsoever...

Twiztidunreal
i need latency for that injectors, can you help me?
