rough estimate of how much a E85 conversion cost? Anyone have a basic idea?

 

[rock_it]

Just done this now...

 

If you get 2000cc injectors new ... About $600

Will need new fuel rail ... Not sure if the ebay cheap ones will work but if do ... $100

Halltech Flex Fuel adaptor .. About $226

Sard FPR (if you don't have one) ... About $200

Braided lines & fittings to do whole thing ... About $500

After market ECU reflash (if required) ... About $200

 

Then comes tuning it... Some places will charge $1,500 just for a tune ... Depending on what you are running.

 

So you are looking at what ... $1,826 in parts ... + labour + tune ...

 

I wish that is all my last mods cost me, but all up, I am down $5k+ ...

Depends on how handy u are. I did mine myself. Welded -6 fittings to each each of standard fuel rail. Turbosmart fpr1200 (overkill I know) 460 walbro pump, modded cradle to take 3/8 barb to 9/16 JIC (-6) made all pressure lines in -6 an 200 series hose and fittings. Returns in 400 series. Bosch 2000s. No flex sensor as yet, as I will have to upgrade Ecu (e8 to PS1000). You can run without, your tuner will have to account for some fluctuations in ethanol though. Some people don't go this far, I'd say minimum would be pump, fpr, injectors, replace the line from fuel filter to rail (to eliminate that restrictive banjo fitting) and tune.

Mine owes me $1200ish and I have an IOU tune at Mick s Motosports, when I'm ready. Still considering PS1000 and flex Sensor, as this will give me more flexibility and assurance.

I'm running purely on E85, not flex fuel but I didn't do FPR, Braided lines or fuel rail - these aren't necessities.

 

Fancy fittings are great, but money can be spent elsewhere.

I agree but a lot will determined by how much hp he's chasing. And i figure do it right the first time and I've seen what ethanol does to rubber hose over time.

[rock_it]

Yeah, much prefer to go down the worse case scenario for pricing, and plan for future... So you don't have to come back and do things.

 

I was deciding between rubber and braided... Or even mixing the two.. But for the little bit extra, thought it was worth it... 

[VIN18M]

I was considering changing hoses over also, but my tuner advised that the standard lines would be fine - Mick from Mick's Motorsport as a matter of fact...

Yeah probably not from a tuning perspective but for longevity I'd say. We did Jamo evo-gsr 2 lines from pump cradle to hardline and eliminated banjo on fuel filter to rail. Picked up 4psi of base fuel pressure at idle. So there are definite gains to be had. In saying that it might not be necessary for all applications.

[VIN18M]

Interesting! Don't get me wrong, I'd love to go nuts on speedflow fittings and braided line.

[Cranked]

Yes I tend to go overkill. And/or change my mind too often.

Lol^

Wallbro 250 pump on my evo 7 and i just scored second hand FIC 1120cc. So i just need to tune it on stock ecu. Works for me

I am the king of overkill ... 

 

Car goes in for a PWR radiator as I blew the stock one... Nek minnit ... $5k+ worth of parts purchased and installed...
