hey guys,

im just wondering if any of you have had success with this?

i'm thinking of getting my RX-7 injectors high flowed... they can supposedly be flowed up to 800cc.

who does it in melbourne?

any ideas on price?

mat :) [/i]
 
i see you are still keen on modding =)

good to see...
ill call my injector guys for a price for ya mate..
see what can be done..

hiflowing injectors aka drilling the pintles out is a band aid technique to make power.. its not as reliable.. the spray pattern in most cases isnt as good as factory and for the cost of hiflowing you may aswell spend extra $100 or so to get a set of new injectors that are that size..

I got some FIC 650cc's from the US pretty cheap.
FIC are shit
what do you suggest mate?

has anyone used PTE injectors?

it seems like a lot of people in the USA have had success with the FIC ones...

where have people been getting these Sard 800cc's from?

Jon, thanks mate, its exactly the information I wanted to hear. :)

FIC/PTE/Rochester/Delphi are all good if you only drive around at 100% throttle. If you want any kind of part throttle tuning, get some SARD injectors, whatever size is up to you.


I got my SARD 800cc set from RHDjapan
https://www.rhdjapan.com/

Was $445 delivered, took a week
 
what makes you say that?

is there some tests that have been done to prove this?

the spray pattern on the FIC's and PTE's seem to be pretty good with the ball and seat nozzle.

who sells the sards?
 
thanks mate :)

im currently running the rx7 injectors which are high impedence... does anyone know how to convert it back to run low impedence?

tharaka, i'd love to know why you say FIC's are shit.

Mine are perfectly fine. Did you put a set in your car and have problems with them?



from someone that has experience
my posts about fic injectors are based on my own experiences. a brand new set of 650's that did not outflow the 560's they replaced. problems from the get go. fic's responces, or lack thereof, and seeing numerous other posts AFTER i had problems. fic flow rates are based on their OWN standards, not the international standards like denso. fic flow rates are less than what they say, denso are more. fic injectors are inconsistent. if you are tuning a big motor, you need MORE consistency, not less. if you want to cheap out on injectors, then have tuning problems down the road, have at it. fic injectors? i wouldnt piss in your ear if your brain was on fire.

fic/delphi/pte/rochester are all the same. dunno what has happened, but delphi went tits up. i heard that bosch was going to buy the building. there was a huge bruhaha about delphi, something about them wanting to use the pension funds to help the company. i think gm owned delphi. and, i say this again. the ONLY reason you see so many of these pos f/d/p/r injectors is because of the bottom line. they are CHEAP. so, companies can make more profit on them. the old analogy, if you got a cheap car, put cheap injectors in. i think they are ok if you want only wot performance. but, if you want everyday performance, idle to wot, midrange, part throttle, etc, they suck. that's my story and i'm sticking to it.
on another note, when i was at ssf, there were a lot of reman fuel injection stuff from fic. they also sucked.

to refresh, i had BRAND NEW fic 650's. when i installed the evo 16g turbo, i installed the injectors. they replaced a set of cleaned and flowed evo 2 560's i got out of new zealand. at 18 lbs boost, even with water injection, they were near max duty cycle. i had problems tuning from the start. they were just inconsistent, and they flowed LESS up top than the 560's. keydiver chip, vpc, gcc, pocketlogger. seems like every time i did wot runs, the settings changed. low/mid settings also changed. it was like they were just not getting fuel(supra tt fuel pump). i just could not believe it was the injectors, because of all the good posts i had seen. then, i started to see some posts against the delphi's. i got a screaming deal on a fresh set of denso 660's, so i installed, and it was like night and day. settings were rock solid, EVEN WITH THE FIC 650 CHIP STILL IN THE ECU. i could do a wot log, and a week later, it would be the same. not so with the fic's. i complained to fic, and they were like, "so what?" fic? eat shit and die.
 
Why would you cheap out on injectors?

It's not even a $100 difference to buy some quality Denso injectors.

You could save yourself a few thousand dollars in an engine rebuild.
 
I too would not recommend getting them "high flowed". I have seen some Nissan ones drilled out and they went from a nice fine spray pattern to that of a drain pipe. Might be fine for a rotary powered drag car, but not much else.
 
Taco is right
I agree with him only because I have been through it with my PTE injectors
Dre with his PTE injectors also.

Bad at idle
very difficult to tune

With the sards / denso's in, an immediate improvement was noticed with tuning and fuel efficiency.

Also the guys on galantvr4.org in the states, especially keydiver (the guy who does the chips) hates the delphi stuff... he would know his stuff..

Go the denso's Matt, your rx7's are denso's, thats why even at 100% duty cycle they still perform well.

I've been informed from FP that the denso's are still quite accurate at 100% duty cycle as opposed to the delphi's 80%
 
One guys account....Not hard proof that they are shit.
I was recommended to use FIC's so I got some FIC's. If they are shit they are shit. Time will tell.
 
give it a shot,
you can still make the power and it could be fine.

its like saying, what is better
a cheapo ssautochrome manifold or an expensive hks stainless steel manifold

they will both make more power
they will both do the job
its just that one will do a better job than the other

honda guys seem to love the FIC / RC injectors
but they also say they only work well under 60psi of fuel pressure...

the only way is to give it a shot and see for youself.
