Question: what components make up a well-designed fuel system for FI?
Im looking at fuel components to use for a turbo GSR. at the moment its not turboed so this is more of a prep or at least something to have for when i do turbo it. GSR block 84.5mm bore B16 head. looking to get about 25 psi and 500whp at most. im looking at AEM fuel rails with regulators and found a kit that has a 320 lph high flow fuel pump. also tips on what injectors i should be looking at ive heard mixed things on different injectors

93 octane and 500whp is going to be tough to make. not saying it cant be done but its hard and the tune has to be spot on

Re: Question: what components make up a well-designed fuel system for FI?
For 500whp I would go with a Walbro 450 and some 1000cc injectors should get you there on pump 91/93 (assuming you make it to 500 on that gas which I highly doubt). Otherwise you shouldn't need to upgrade your fuel lines or rail. Never a bad idea to upgrade to a nice adjustable FPR such as Aeromotive, and a higher flow filter like Fuelab.
With E85 you would need to upgrade your filter and lines, and run bigger injectors.

Re: Question: what components make up a well-designed fuel system for FI?
Are you saying upgraded lines as in larger diameter to meet 500 whp for E85, or upgraded lines as in a different material to handle E85? I ask because I'm running stock lines from the tank up to but not including the engine bay on my car, and only have updated the engine bay lines. But, my WHP goal is 400 or less.

You don't need either in all reality. E85 is definitely harsh if left neglected and can cause significant damage on fuel components. If you're up on your maintenance, you can absolutely run E85 on stock lines/fuel filter.
A lot of people seem to be hesitant on E85 because of this, but you really don't need much at all to run it reliably. Hell, I ran oem lines,filter on used factory S2K injectors for 4 years with no issues.

E85 supposedly eats away at anything rubber, so you need to run PTFE lines. The disintegrating rubber lines will gum up your fuel filter and/or injectors.
Also, for 400+whp on E85 I would run at least -6 feed lines.

Isn't the stock hard line (feed) equivalent to -6AN? I have heard that the banjo fitting at the hanger eventually becomes a restriction, but not sure at what power level / fuel flow requirement that is at.

OP if you do run E85 you can easily make 500whp on ID1000's and stock lines.

Pretty sure 1000's will run out before 500whp on E85, unless you are bumping up your fuel pressure. Mine run out in the 400-450 range with a stock FPR.

Re: Question: what components make up a well-designed fuel system for FI?
Yes I am using E98, and I am using PTFE lines however back in the day I used the PTFE lines from my engine bay to a fuel filter to the rail and to a return. All my lines were stock from the engine bay back and ran a stock fuel tank. I mean obviously things have changed on my setup over the years, I know have a 1.9 gallon fuel tank in my engine bay but don't get concerned with E85 unless you are planning on driving the car months at a time.

Re: Question: what components make up a well-designed fuel system for FI?
I thought -6AN was larger than stock, maybe it depends on what chassis? Also maybe it does have more to do with the size of the AN fittings themselves more than the I.D. of the hose. Idk this is just what I've heard.

‘I’m surprised you reached those power levels with 1000cc’s , im guessing you raised the baseline fuel pressure? I’m already close to 50% duty on my 2200’s

On our EG chassis, -6AN is larger than the stock hard lines. The AN hose fits pretty loosely over the hard line.

Re: Question: what components make up a well-designed fuel system for FI?
I had to improvise on mine when the silly conversion fitting was leaking.. I fit the hose over the feed and had to use 3 clamps to keep it secure. Lol! Crude, but effective.

My buddy runs his turbo integra on stock lines with E85 no issues. I want to share this link in case anyones interested.
