howzit guys!
okay, i need some help. i'm looking for options to increase fuel delivery.
(6i). i believe our injectors put out 220-230cc, and i'm looking for maybe 440cc...480cc max. wondering what other cars would have similar injectors that i could just swap out, or if there are any ways to safely increase the flow. i looked at our injectors and found the ID# 180 256 256 on it, so i know it's bosch. but i can't find any info on these injectors anywhere. i've searched and searched, but nothing. i do know that ford tests their injectors @ lower pressures than other companies, so maybe the stockies would be okay, but for how much boost? .
i'm gonna throw a t25 turbo in it, totally custom setup, run 8 lbs max boost (just for that extra push when i need it). i have pretty much everything i need, just need injectors. i have an emanage that i'm gonna hook up soon, done months of research on it, so i am confident it'll work. i was gonna use the stock injectors and control the fuel with the emanage, but then i realized that i might burn out the injectors, so i dunno. any info on this subject would be greatly appreciated. i've been researching this for quite some time now and i really wanna get that turbo in already, it's been sitting there in my room for quite a while now (almost a year), so please help me!!!
mahalo in advance.

thanks, i already emailed them. they said they do sell them seperately for $395. i'm just trying to scope out the possibilities before i dive in and buy them. which i probly will do anyways, but what the heck.

how much boost do you think the stock injectors can safely handle? if ford rates them about 21 or 22 lbs, and they test their injectors @ 40 psi, since our cars fuel pressure is 64 psi max, wouldn't the increased pressure amount to a higher flow rate? i really wish i'd taken math more seriously now right about now. thanks again for any info you guys can share with me.

better luck talking with the guys at SCI over on mazda3forums. they sell a turbo kit using the emanage for the mz3. it's pretty easy to buy injectors with the tail and splice it in place.

well, if you really want to try running more fuel, you can get a manual fuel pressure gauge hooked up and put a hose clamp on the return line, along with a higer flow rate pump (?). Not sure how well this will work on the 6? tighten the clamp till you see 35-38psi on your gauge be my guess. of course you may very well break something doing that. not going to equate to a higer flow rate, but it might.
I dont think i'd try it myself, at least not on the 6.

hey MrTea!
i see in your sig u have 60lb injectors...how did u manage that?! i'm guessing you don't have a stock fuel rail. or stock anything for that matter LOL! how did you go about your fuel delivery from when you first boosted until now?
i was planning on buying the injectors from the hass kit (since they did leave me a quote) and throw them in this month, but with xmas coming and alot of friends and family to buy gifts for, i just can't afford it. oh well, maybe january or so. that's why i was wondering if there was any cheaper way of getting more fuel delivery out of our stockies.

the 60's slip right into place. i was running some 36lb injectors that come with the HiBoost kit, so the pigtails were already changed out. the 60's just slipped into place. nothing else on the fuel side is changed. i can run the 36's up to 15psi to redline without much bother, but wanted the 60's for safety sake. can't run the 60's until the manifold is swapped out though, spray pattern and intake flow just down work at idle with the 60's.

like i said though, you can get a bunch of injectors to fit the rail, it's more making sure you get the pigtails with them so you can splice them in place if needed. the Emanage can run high or low imp. injectors, so you should be fine with either.

you just need tails for whatever injectors you have if they are different than our stock ones

alright, thanks guys for the help.

new question though...
so i have a greddy electronic boost controller (profes type-s) and i was wondering, the instructions say to connect a hose to the vacuum side of the fuel pressure regulator...obviously this will not do. is there any other place in the fuel system that i can tap into that would work? i did buy a mbc just in case though. any suggestions?

*just a warning, i may be asking a few more questions after this one, so thanks in advance for any help. :)

i just don't know the type s unit. it's usually just for pressure reference, so any manifold vacuum line should be fine.

Just a side note on the clips FYI:

Our stock clips are "EV6" style I believe, and most aftermarket injectors that fit our cars use the "USCAR" style clips. I found this out when I changed over to the 60lb Siemens (sp?) injectors for a whole day. What you can do is ravage a late model ford Escort or Dodge Neon at your local U-Pull It yard for cheap and get the whole length of wire with the clips we need. For me it made for a cleaner install for less money. It cost me $2 plus tax.

MrTea is also right about the 60lb injectors not working at idle!!! I found out the hard (and expensive) way. BAD IDLE!!
