2jzgte + AEM + e85.....injectors and other questions

[empera]

so im swapping in an aristo 2j into my 87 and i have some questions...motor is almost ready to go in but i still need to purchase fuel injectors. The FIC Fuel top feed rail i bought isnt going to work with my old PTE 780cc injectors but thats ok because i want to run e85 and will need a 35% increase in fuel. It looks like the rail needs DOMESTIC style injectors and they need to be longer than the PTE ones i have.

Im thinking 1000-1200cc will work but they will need to be domestic style. Any brands you recommend? I'm trying to stay away from RC's.

Also i was told i can run low impedence on the AEM EMS without a resistor, is this true? If anything i will wire up a 7m resistor but its just something that will consume a bunch of time if i can just change some settings on the AEM.

Right now the aristo is set to run on high imp. injectors but from what i've seen its best to go with the low imp.

I think thats pretty much all the questions i have for now, i'm sure i will have plenty more.

Thanks!

If you want to spend money on the best then Injector Dynamics is the company to get. But if your on a budget they do make the PTE injectors in domestic style in that size. Are you wanting to get away from PTE as well?

 

[empera]

kinda, PTE seem to work but i think ID's might be an option.

Looking at 1600cc ID's as i write this lol



also any idea on the whole not need resistor with the low imp. on the AEM v1? Flateric told me he uses low imp. on a AEM v2 without the resistor.

Siemens/Deka are good shit.

What are your power goals?

 

[empera]

700 would be my ultimate goal so i'd want my fuel system to be able to handle it but 500 is pretty much my immediate goal. I have an a1000 pump with a -10 feed, splitting into 2 -8 AN's onto the FIC rail and an a1000 fpr with a -6 return to the fuel cell.

1000cc seems like the max you would need for a goal of 700 rwhp, you dont really need to over kill it too bad.
Enslaved87 on here makes 640rwhp on E85 with some 850cc's on his 1JZ, something to think about.

Also, -10 feed is probably over kill also, but if you already have the parts might as well run em.
My set up is -8 feed all the way to the rail and -6 return.

A1000 might not be enough for flow for 700 on e-85 unless its a modded version, 1000cc should be more than enough for 700hp on e-85 & I would wired in a MKIV resistor box instead of a MKIII resistor box, The MKIV is set for Sequential injection instead of batch... Anyone is free to correct me if I am wrong..

Empera where did you get you fuel lines from? My plans are just about the same as your. Keep this thread updated. I'll be following it.

 

[empera]

so appearance ID injectors only come in High Imp (saturated)......any benefits in staying with the high imp. injectors?

got the russel push loks from summit...have been using them for about 2 years on pump with my old 7mgte and still the a1000 pump....

So far i've heard ID injectors only come in saturated style....but these are suppose to be really good injectors. I'm a little confused since people on the forums say to run low impedance but i was talking to a tech at FIC and they told me the high impedance (newer injectors) are the way to go. By the looks of the price you would think that the higher priced saturated style (high imp) would be the best decision.

Anyone have some info?

 

[empera]

Ok i went with the ID1000's to accompany the FIC fuel rail.
I haven't started it yet but i should be able to soon.

My current issue is the following. I'm contemplating in either running my -10AN feed and divide it into 2x -8AN and feed those into each side of the fuel rail. OR should i keep it simple and feed a -10/-8 AN in the rear and will it be enough? I can only go as high as -8 fitting on the rail so im not sure if it would make a difference in using a -8 to -10 adapter fitting.

Also the return is a -6 all the way through, is there an advantage of running something bigger? I dont think so but i may be wrong.

I will post a few sketches to help you decipher what i'm talking about lol...

 

[empera]

The first option is simple and easy but would there be a bigger advantage in doing option 2?

James had ID1000 with Precision 7675. built everything, dual bosch 044 and only made just shy of 700 IIRC. he had to upgrade to the ID2100, now is making 800 something

Oh ANd do the 2nd option. or at least if you do option 1, make the return on the opposite side of the rail

 

[empera]

is there an advantage on running one or the other?

 

[Albert]

not to sure. Either way they are in parallel. I dont prefer this setup. Id go with an option 3. that is just me. But this is the way im doing it with my ProEFI and Bosch 044:

Run 1 Bosch 044 intank, fused relayed. This pump will run -6 all the way up to the front port of the rail. it will be running 95% of the time.

Run the 2nd bosch 044 in-line, (-8 suction. -6 feed) run it to the other side of the fuel rail. This is fused and relayed to the computer to ONLY kick on when I go past 5psi.

the middle port of the rail obviously would be the return.

 

[empera]

is e85 going to do any damage to my russell "push lok" lines or fittings?

what about the composite fuel cell?

 

[Albert]

I have Push lock on my Flex fuel sensor, But thats just the Fitting, as long as there is no rubber in the system, I think you'll be okay.

My roomate is running E85 on his talon with all rubber lines, Hasnt failed him yet.

Not to sure about the fuel cell?

might need to change that....

Go option 2, -8 to dual -6 feeds or keep it all -8 but T off near the rail. Unless you are completely set on a -10. Keep an eye on that pump pressure full tilt either way. I know my Magnafuel 625 will flow enough E85 for over 1000rwhp, and it's only a -8 outlet. Flows more than my A1000, I am certain of that. Go with a good FPR, it will help you go further with a pump maxed to the limit.

I would get high imp injectors, at least 1600cc. Any newer injector is going to win, there is nothing wrong with older units. Give yourself some headroom on injectors and buy them once.

If you decide on option 1 for the fuel delivery, I would suggest blocking the middle return. Run a single -8 into one side of the rail, and straight through. Simple, easy, least expensive. Run the -6 from the rail outlet all the way through the FPR back to the tank.

I know of no negative reason for a -10, other than the more fuel in the line to push all the way up to the rail, the more work the pump has to do to meet the pressure demands.

I hope you wanted to make 1000+rwhp.

 

[empera]

already have the ID1000s and already have the -10 line ran from before.

gonna go with dual -8's on each side of the rail and -6 return to a1000 FPR.

just need to make sure the hose can handle the e85
