Damn you e85 guys
 

Well whilst browsing the forum while away from my car (I'm in China) I stumbled upon you guys that re running e85 and it looks quite inviting. The time i have spent here i have been stashing away cash to finish my project thats oh so far away in the US.
I do have some questions as to the conversion. I understand i need more fuel and a lot of it. What do you guys recommend for pumps? My original build spec is for a 13rbe hbp and a gt500r turbo and running on a haltech e8
Now that i have the engine sorted out and purchase (just awaiting a rebuild when i come home), and have settled on a turbo which i will be purchasing next month (when i return home for holidays and get the motor in to test fit mounting location)
I move onto fuel delivery.

So what you would recommend for such a setup.
fuel pumps
would 4x1600 injectors work? and what kind of limitation would i run into?
If 4x1600 isnt enough where should extra injectors be added?
I plan on premixing already and have read up on recommendations so thats fine
Do you guys run anything different for plugs when running e85?

This car is not a daily driver just a fun on the weekends kind of stuff, will be hitting autox and some track events and more then likey get drug to the strip by my friend and his huge hp 300zx.

Luckily in mid MI where I usally live has plenty of e85 stations and the prices seem to be fair.

I will speak from experience in getting my car setup.

I have seen that if you are going for the 400whp mark one fuel pump and 4 1600cc injectors would be just about what is needed. But that combo would be approaching it's limit at that. I was able to run one bosch 044 pump with 6 1600cc injectors up to 18psi on a H1E ( air flow equivalent to a T-67) on a stock REW and could have done that with just four injectors. I have no dyno number to justify my power output but a T-67 on a stock port at that boost level is in the 400whp area.

Also you do not need to go nuts with rebuilding the fuel system if the 400whp is the target. You can run an intank pump, but you should add a very substantial grounding strap from the fuel pump through the tank and then to the chassis. You should also insulate the 12v power source to the pump from being in contact with the ethanol. No need to freak out, just the issue of ethanol being electrically conductive needs to be addressed.

I have been using BUR9EQ spark plugs with no issue.

Thanks for the info, I guess i should have stated my goal as well, like to see around 420hp, and possibly grow some more later, but I feel 420hp with that setup shouldn't be too unattainable

Well i did 530 at the wheels with 4x1680cc injectors and a base fuel pressure at 45 psi. But i was also running the Aeromotive Eliminator fuel pump, wich delivers enough fuel for 8 1680cc injectors i belive.
