Thx applz..... i just finished reading Modaddict's journal and it took me a damn hour!

I miss the sound of my wrx, and want it SO bad on my STi.... but after seeing his progression.... i just dont know now if i want to get tuned for stg 2 or go for CP30R sooner..... I'll most likely be doing stg 2 + saving cash then doing the turbo the "right" way in my eyes... im just really anxious when it comes to my car.... thanks for the info, im tired.... p34c3

yup, I have the "magic" 720cc injectors hitting 80% duty cycle.

I'm honestly not sure if they will be enough for you. The E85 requires more fuel. Im 100% ok with running 100% (or beyond) duty cycle...but that's just me. Most arent.

I don't have the experience with e85 to tell you....even though, i have a pump near me and would 'LOVE' to try it.

The only problem I see with e85 is I hear it's inconsistant as far as equivalent octane rating. if you go to the pump and get tuned for it and it's 110 octane....I hear next week you can get a 105 rating. That scares me. is it 100% truth? I don't know.

Crawford will jump to the 900cc injectors on their "big builds". still with a 35r though.

i suggest if you don't go with I-speed, then talk to your tuner and see what he recommends.

Im sorry, I don't remember the price for them. I know they were more than I though injectors would be...but, in the long run, whatever.

Sounds good, i talked to my tuner yesterday and hes running a perrin 30r on this WRX (not sure if its an STi swap).... hes using, and highly suggested using a standalone ECU.... i might take his advice... as for injectors, if i dont go w/ the CP 720cc ones im not really sure what i should get so i can use them for stg 2 as well as the turbo upgrade

please take no offense to this:
eeek. your'e comfortable running 100% IDC?? that makes one of us!
If you get any kind of problem at all with 100% IDC its usually a fatal problem ((for the engine)).

As far as the injectors, i was in need of an upgrade. I heard great things abour Deatsch werks 740cc, and Power enterprise 850cc. My determining factor was after learning more about how they work, the lower the #cc the better vaporization of the fuel. In other words, 740cc is the largest i would go because it still let the fuel atomize before entering the cylinder instead of just squirting it in. each injector is designed to operate at a certain psi for a "volume of flow" & a flow pattern. 720cc or 740cc whatever, i only recommend the 740cc because i got them for $489 shipped. They work great, and give me room to upgrade to 20g-or biggest 30r later. just research and decide what YOU like before you upgrade.

I was also reading that the E85 is inconsistent. that is a main reason why i havent played with it (yet).

BTW: since you're a DIY guy like myself. here are the links i used, i suggest following them (unless you already know what you're doing).

LOL damn beers... I meant that its good he wasnt blowing smoke at you claiming numbers and his #1 concern was safety and reliablity.. Thats what I meant... I have to start proof reading more..

For injectors I would research aswell, I went with the DW 740cc also knowing that in the future I would be going to a 20G or Green at max, I am not to famliar with the Magic 720cc but I would see if they are gonna be enough for your future plans. I just dont agree with running IDC @100%, you really dont want injectors to be Static which basically means running them fully open all the time or 100% IDC. If you read most injectors recommended rates they state that you should not exceed 80-85% IDC I dont think that running them abpve this is gonna make a diff, but i wouldnt run them @ 100% just my .02..

[howboutthemapplz]

^agreed, all injectors have their "efficient" spot. which is likely NOT 100% IDC.

if you try to squeeze too much out of the injector the flow pattern goes to ish.

No offense at all. But it is know that fuel is added, significantly beyond 100% datalogged.

The only true way to tell is with an occiliscope. People have seen added fuel until 125%.

Read: im at 80% on my 720cc injectors. at 26psi of boost on water/meth 81% on 20psi 91 octane.

Mod PMed me what he thought he remembered paying for those CP injectors, and i think that theyre a tad spendy, even if i were to wait for the turbo upgrade..... For a rotated 30r from crawford performance, does anyone have any recommendations on injectors? i probably don't want to run 100% IDC... just so i can have some overhead if i need the room later on.... i understand what everyone's been saying about the E85, but if the tuner is THIS confident about tuning w/ it, and has already tuned more than a few cars on it, its worth giving it a shot IMO..... i did forget to ask about how it would change how often i need to refuel, or how it would affect the gas mileage

I was too lazy to post my planned Stg 2 mods on the 1st post before, but i'll make a little section there now so i can at least keep track for myself of what i need to get for stg 2....
Mod your gonna have to help me out later, my mind is kinda.... forgetfull, and i'd like to make a similar list for the turbo upgrade.....

What do you think of using standalone compared to the ECUtek?.... tuner said that it was possible, but he wouldnt like it... hes uncomfortable w/ the stock ECU pulling timing whenever it damn well pleases.... with a standalone he can fully trust whats going to happen because it does as its told... (not his exact words but damn close)

you will get less fuel economy, period.

exspecially at WOT.

W/ injectors? E85? the turbo? what part are you talking about lol
Anyone else wanna comment about the rest of my questions in post 98 pls
