So ive been searching for an answer and there was a thread on her a couple of years ago but no one had done it then. So has anyone done an e85 conversion what are the pros and cons what did it cost. Is it worth it?

Depends where you are at.

im currently transitioning. its not cheap. you need an ECU new fuel pump and regulator and injectors. you should also swap to flex fuel capable lines (doesn't have to be braid gates sells the barricade range).

 

rewards is more power with less risk of detonation.

cuts should be able to chime in but it certainly seems like 10% more power is expected as a minimum, obviously the more extreme your set up the higher the returns.

and if you have a petrol map then you need another E85 map, if you want flex fuel then mapping is expensive.

 

so if you have a stock car then no far from worth it, if you are running and aftermarket ecu and decent turbo then yes its likely cheap power.

haltech ps1000.

excluding the ecu.

so flex sensor, lines, injectors, regulator and pump.

you wouldnt have changes from $1600 but i did use teflon braided lines (about $300 worth).

plus the turn $900ish...

 

didnt think p platers were allowed modified cars in QLD and ethanol is pretty easy to pick up (smells sweet).

apart from that i dont think you will see huge gains, but then im not familiar with 2zz's

This is the thread you're looking for:

http://www.ozcelica....5-on-a-7th-gen/

+30wkw for sueprcharged celica i think.

For cost wise and value, is great for reliability (runs cooler) and safer than turbo charging (check all seals etc).

IMO, the cost of e85 (cause mieage is a lot less) will outweigh the total benefits after a while, you'll need to run it  on a track / weekend car.

Unless you run flex sensor and do 98/ e85 build.

btw - you can run a 20% E85 / 80% RON98 Mix on a standard car without doing anything to the ECU - for fun !

Because Stock ECU's usually run the AFR too rich, it means they can drink a slight mix of E85 with the factory maps.

e85 has rating of 100 to 105, but runs cooler. Mixing with 98ron, will give you a final mixture around 99-100 (the same can be possibly gained with octane booster additive on 100% 98RON).

Honestly, e85 cost + mileage isn't that great. It's only good for FI + or NA setup with super high compression.

Anyways, been reading up more about e85 vs RON98, best commit to one setup or Flex Fuel (more cost for added ECU etc). Mixing it is pointless, and the stock ECU won't do much to 100 octane rating (unless you trick it into pumping more air +fuel - don't know how you'll do this with stock ECU)

Hey ausjd2703 did you change the hard steel lines? Or just the high pressure lines from pump and from fuel filter, oh and the return line.

I've taken my fuel tank out so I thought I might as well go down this road.

Didn't touch steel lines left them be as apparently their not an issue.
I've done firewal to engine stuff. I'll fix up the tank stuff shortly as I'm about to install the fuel pump

That's good to hear.

I've ordered some e85 hoses including the one inside tank. The small hose inside the tank is submergable and I've found that it has to comply to SAE 30R10 to use e85 or normal fuel so it doesn't swell up. I'm still trying to sort out the high pressure line between the pump and the hard steel line, I'm might have to pop into pirtek.

Gates sell a hose for intank. I'm getting it through work (Cbc bearings)
The bit of flexible line im likely buying more speedflow :(

That's what I'm getting. we get bearing from you guys but mainly from cbc nsw branch, I work for Favco cranes..

I was also think of using speedflow fittings but they are expensive...
