Ve gts
Just looking at setting up for e85 and was just wondering what needs to be done and what generally is the cost. I have a ve Gts and I believe the fuel lines and tune need to be changed.

From what ive seen, you need the sensor (like what on the s2 e85's) to messure the amount of ethonal in the fuel and then a tune.
Should be under a grand and reap an extra 10 - 15 rwkw up top.
Lots of people say you need to change lines, rubbers, filters ect but its bs.

I would recommend changing lines.
The standards are not rates to carry ethanol.

I'm sure they be fine, but they may leak

Going by my experiences on my R33 on E85, it is recommended to change the lines but isn't an essential MUST DO thing, as long as the fuel isn't left sitting there for a set period of time, they should be fine. If it's a daily driver, I can't see too many issues with the lines, with the exception that you may notice a stronger fuel smell.
Having said that, some fuel pump internals cannot stand E85 and if the fuel is left sitting in the tank for a lenghty period of time, it starts detioruating the fuel pump.

I also had to change the injectors from 740cc to 1000cc, mainly due to the fact the greater the ehthanol content, the more fuel is required for a "burn"at a given load.

Being a turbo car, I gained just a tad under 50rwkw (348rwkw) by switching to E85 (and the supporting hardware) and getting it retuned, with the midrange fattening up substantially (i.e usable power). With N/As, the gains are less I heard.


Again, all of this was my experience with an R33, but still something to think about for your VE as I've toyed with the idea also but down here where I am, it's too out-of-the-way for me to get E85 as the VE is a daily driver.

Correct me if I'm wrong but wouldn't e85 burn a lot quicker than normal 95 or 98? Therefore resulting in worse fuel economy, just curious.

similar effect on E10 but not as exaggerated, just that people are too dense to notice and only think about the pump price. As is always the case though the fuels are priced accordingly so the fuel company makes the same dosh out of it.

E85 does indeed give you worse ecconomy BUT, it's better for the environment (If you care about that side of things) & you do get better power & torque. The biggest advantage is it costs less at the pump (Approx $1.20 per L).

I'm running my ute on E85 most of the time & getting somewhere around 300-330 kms per tank in town, whereas I get 400kms + on 98.

Heaps of the Jap car are getting switched over to E85 these days. They require larger fuel pumps, larger injectors & a tune at the very least. The advantage we have with Holdens is that you can obtain the ethanol sensor which is a genuine part, which allows you to run normal fuel as well as flex fuel without having to manually change maps etc.

I had my car tuned with Walkinshaw Newcastle a few weeks back... With 3 inch cat back, HSV headers & VCM OTR, I got a 50hp gain & a 93nm gain all on E85... Car goes heaps better, but yet to try 98 to see how it goes. I could notice a difference when the car was stock for reference.
