Ok so I have a 99 si with the original b16 recently built (pistons, rods, block gaurd) and also a full valve train.

I was wanting to run e85 and after calling cft they confused me more then already was. They recommended 1680 injectors and dual fuel pumps.

My question is what companys offer 1680s and how does the dual pumps work. I have one walbro 255 and cft said I need another. So do I get one just like the one I have or is there a special external one I need. And they also mentioned bosch 044s. Which should I go with?

Without knowing a power goal nobody can help you

on an na motor, you wont get the full benefit therefore there isnt much point

not to mention you cant run e85 on a stock obd2 ecu as theres no way to compensate for the added fuel e85 requires

A very specific description of your motor and turbo setup will allow people to help you more.

its not sleeved just .040 over
my original goals were 450 because my buddy has a dyno sheet on his teg that says 422 so I just wanted braggin rights, but CFT told me Im easily lookin in the 500 range.
Then today they said on e85 I can look towards 600 but without sleeves wouldnt push my luck and gony more then that.

So im gonna let them tune it when the builds done and what ever it gets it gets.
but I wanna run e85 and just need advice on the fuel pumps and also a good named brand for 1680 injctors

I'd go for a set of ID1600's as I know 1000s will max out between 5-600 on E85, sorry can't help you on the pump as I don't have exp at that power level but I'm sure someone else will know.

spoolie

Internal and a external along with upgraded lines should get you there. FIC makes 1600's.

We just made 500HP on E85 @ 20 PSI with a new Aeromotive drop in pump and FIC 2150s.. not out of fuel yet, gonna turn it up a bit more soon.

This is on our mustang dyno. Thats like 560-570 on a dynojet with a single drop in fuel pump. You don't need twin pumps to max out your sleeves ;P

^Whats the LPH rating on the aeromotive intank you used?

spoolie

Exactly...the old Walbro's only do 240...I've seen a 300 on the net, but not in person yet. The Aeromotive is probably a larger LPH pump. Most E85 setups usually use minimum of 2 pumps.

BeastModeSi

so what pumps should i get to achieve my goal. Im lookin to nail all this the first time around so if i should just sell my walbro and go with another company then idc to do so. So with aother walbro should I be good? and how does that install work with two pumps that are made to be intank? (sorry im kinda new to this I just came across money from a motorcycle wreck so Im building my dream honda)

BeastModeSi

id also like to kno this question. I cant find it on google for some reason

K20egcw

I would just go with some ID1000's and just raise the fuel pressure if you need more.

BeastModeSi

another question I just thought about... I have an aem fuel rail and regulator. Are those fine to use? and do I need any kind of fuel lines with all this?

brands would be nice if you guys know any thats good

K20egcw

No you dont need any special lines or anything like that and the AEM rail and regulator will work just fine

BeastModeSi

thanks dude

If you do decide to go with an extra pump, its an inline fuel pump your looking for. There are other options, like the full blown intank dual pump set up, or you could do dual bosch 044s and sump your tank. Its up to you.

If you already have a walboro intank I would say run a bosch 044 or even possibly just an inline walboro

K20egcw

My friend had a built GSR with a Precision 6262 that made 543whp @ 18psi on E85 before he started running out of fuel with a single Walbro255. I would run both a Walbro and an inline Bosh044 (another brand will work also) just to be on the safe side.

^ What size injectors was this on?

K20egcw

They were RC1000's

I know this is a different motor, but I also have a friend that had a 618whp stock K20a2 with 1000's also on E85. He was running both a Walbro and an inline Bosh 244.

Many people fail to add up the cost of running dual Bosch 044's, by the time you sump the tank, buy the fittings/line and the filters your in close to $1000 if not more and its way overkill for most setups.

Intank 255 to Inline 044 or dual 255's and a set of ID1000's will suit you just fine.

I ran an Intank 255 to Inline 255 with RC1000's, AEM Rail and Reg and made 585hp on a dpack on E85, so rougly 530 on a djet.

heres all the info on the pump..

A good single is the way to go.. I've seens too many times where one pump in a dual pump setup fails and you end up melting somthing.. If your on a good solid stand alone that has fuel pressure monitoring and lean protection, then sure.. Otherwise just get a good single pump setup that suites your fuel requirements.
