Hello I'm kind of stuck on what to do next I really don't have any experience with ethanol and I have a fresh build that I want to run E85 on my setup is 81.5 X 89 mm 12.5 usdm Integra Type R Pistons lsvtec running OEM Type R cams any info I would greatly appreciate it thank you

 

Besides a bigger fuel pump and injectors, you'll need to get tuned.

Best thing to do is ask your tuner what he prefers to tune. Some like certain brand/size injectors.

 

As of right now I have a stock fuel system but I've started to gather parts so far this is what I have
●450lph walbro fuel pump (e85 compatible )
●napa 4003 fuel filter
●aem fuel rail
●nitrous express fuel pressure regulator
●injector dynamics 1000cc injectors

Where I'm stuck at is determining what size/type feed and return lines to run
I'm just trying to go to mexico soon

 

I ran a walbro 450, ID1000s with stock lines besides from the factory fuel filter to the rail, and rail to FPR. This supported 560WHP on e85.

So run any sized lines you want, typically people run -8 feed and -6 return. You can use as much factory lines if you want and it will be fine for your setup

 

Why are you trying to run such a big pump? Are you turbo'd?

Same with the fuel lines. Why do you think the stock ones are restrictive? The bigger your pump and fuel lines, the more fuel is going to be returned to the tank for no reason.

 

Reason I got a 450 pump was because I have plans of slapping a turbo on but that's a while from now just planning ahead

 

For example is this filter too big? Its bigger than my rail lol

 

Is this a daily?

 

Yes will be daily driven

 

cool fuel filter, lol what micron is it? and what fuels is it good for?

 

7 micron e85 compatible

 

Find a tuner and talk to them about your goals.

Two smaller fuel pumps might be better for a daily so you aren't returning huge amounts of fuel back into the tank. One for cruising around, and the second kicks in when it's needed.

Fuel pumps heat fuel and if enough is returned to the tank you just end up with hot fuel. Hot fuel isn't as dense as cool fuel, and if it gets hot enough, you can run lean at the wrong time and pop your engine. This isn't so much of an issue if you have a fuel temp sensor and the car is tuned for it, but that requires some fancy parts and ECU tuning.

 

Thanks I will look into this appreciate it guys ��

 

Soo has anyone ran a non bypass fuel pressure regulator? I have this regulator but I'm not sureally if it will work on a honda setup
