I was filling up at caltex with 98 and some guy in a turbo'd mitsubishi asked if the V35 runs E85, i was like wtf is that, and he said caltex now has it, its called flex or something.. he runs it after he changed his fuel filter and says he gets much better performance and almost as good mileage...

Anyone confirm if we can run this?

Thanks

Unsure about v35 but i know R32, 33, 34 would need to be tuned for it. It burns cooler and with less knocking, with potential power gains. Use your search function there are whole threads on this stuff.

Well that was a long read... Thanks ! I tried to find if our car can run it but after reading that i doubt i would bother... If i didnt have to change anything to run it i would give it a few tank full runs ... Any one know?

no- you cannot run a V35 on E85 without reprogramming the fuel and ignition

the only cars in Aus that can take it in OE spec are the recently updated Flex Fuel Commodores (and possibly some new Bentleys, but don't quote me)

There are I think 4 models of cars that can run E85, they don't make any more power over petrol because their engines are designed to run on 91 also, which means the compression is too low to reap the benefits of the higher octane.

You would need to bump up the compression to around 15 or 16:1 and remap the ecu to see any real gains on the VQ35, You couldn't run petrol again if you took that route. That said there are other ways to increase compression, supercharger and turbo, either could easily double the power of your engine if you ran ethanol.

You could probably run a mix on your stock map, perhaps 1/3 e85? It will re-learn the fuel requirements and as long as you don't go too much, it wont throw a error. You would expect only small gains and up to 20% worse fuel economy.

Ethanol is a very clean burning fuel and carbon neutral. (other than the production/transport of it) The only down side I have found, you will need to fill up more often, and there aren't that many servos yet. Caltex do also plan to vary the mixture, between e70 for winter and e85 for the warmer months, (This is to help with cold starting) although they have tanks full of e70 still due to the low demand. This wont pose any problem if you tune it a little on the rich side.

Well according to this article from The Age, there seems to be no point running it on E85, as it costs more to run overall compared to Premium 98RON, so what is the point of it? And like the others have said, I wouldn't go anywhere near your V35 with E85 petrol.

Just look at this chart, why would you risk it anyway? And this is from a car that is designed to run on E85 fuel from factory, seems kind of pointless to me. Stick to higher-grade fuel and have peace-of-mind.

As with any alternative fuel, you just can't throw it in your tank and expect a good result. E85 will not just require a specific tune. You'll need to ensure fuel lines are compatible (usually only teflon lines) and to get the most out of the fuel you may need aftermarket Engine management. Check out the E85 thread, there are certainly performance benefits to be had on a modified vehicle. As for the article I'd look at it in the correct light. On a stock standard vehicle like the commodore E85 the tune will be conservative and not at all performance based so results may not be all that impressive. Just for reference the V8 supercars run E85.

Sorry about the long read but i am a fan of giving people a certain amount of info and seeing if they can figure it out themselves(Give a man a fish and he will eat for a day, but teach a man to fish and he will eat for a lifetime) + i don't think u used the search function as suggested. Guilt-Toy has been using it since 2008 and on the first post he, through his story explains about its usage and the need for tuning. However that link i posted from his thread also gave you the answer but i guess you glanced over it, which is fine as everyone is unique.

"Ethanol started off as the bad boy of alternative fuels, damaging some fuel systems not designed to take what is almost pure alcohol - albeit with additives to make people vomit if they drink it and blended with petrol in varying ratios."

"In a classic chicken-and-egg dilemma, car makers and fuel companies have been at a stalemate about using the fuel in Australia. Fuel companies haven't rushed E85 to market, given only a handful of cars are engineered to take it, while car makers argue there's no point selling E85-compatible cars because you can't buy the fuel.

Last year, though, Holden bit the bullet by modifying two of the three engine variants available in its top-selling Commodore range to run on E85. However, Holden wasn't the first to use E5. Saab, Chrysler, Dodge and even Bentley offer E85-compatible vehicles."

Nissan is not listed as a maker of cars from factory that can run e85, at least according to the article.

Good luck to that fella chucking it in his turbo Mitsubishi.

Oh dont worry i read the whole thing, i should have then asked (since i was told there was a 40c difference in price) if anyone bothered to get a diff fuel filter that can handle both fuel and the article said if E85 is more than 25c cheaper its then in your favour.... I wont bother now after reading it and people confirming you need a specific tune etc...

Yeah that Mitsubishi guy said he just replaced the filter.... :/

    • Nice, thanks for sharing your progress....that's a pretty long list you are putting into it!
    • Decided to upgrade my pressurised plastic coolant expansion tank for a fancy pants alloy version The OEM versions can get brittle, even the new plastic one I got when I first got the car is a starting to show signs of "stress" I wasn't cheap, but it is basically unbreakable
    • Morning all, I have an RB25DET Neo that's in need of a rebuild. Will need new pistons etc due to detonation damage. Would anyone be able to recommend a shop in Southeast Queensland who I could bring my long motor to for a rebuild? Just want someone who knows RBs and whos built a bunch of them before. TLDR - recommended engine shops for RB rebuild.
    • Gday Thought it was about time I started a build thread! As expected this project has snowballed into a huge financial liability, but unless you’re strong willed and responsible, it’s not a surprise. Background -  My first turbo car was an R32 GTS-4, got my full license and then totalled my Au Falcon a week later, so while trying to sell my RMZ450 dirtbike to buy another car a bloke offered to swap the R32 which at the time I felt like I was ripped off but looking back and seeing prices of those now ($40kish) it was a good deal, I didn’t know enough about these cars to appreciate what I had so sold it before the RB20 blew up. Between here and there, out of 12 cars I’ve owned the note worthy ones are a V8 Lexus SC400 (soarer), a couple of XR6 Turbos and my beloved S15 which I had for about 3 years, picked it up for $12500, repairable write off but she was fine, gun metal grey/pewter and bone stock/unmolested until I got my hands on it. Ended up spending about the value of the car and 280kw, 2 demerit points by the time I got defected and sold it for $14500 (also $40kish in today’s market, rip) Fast forward to the present day, I’m in a much better position financially and daily an MQ Triton (great cars, pipe down Ranger Bois), I cruised marketplace and car sales for a few months looking for another R32, the best deal I could find was an absolute rust bucket half finished project for $12000, until this R33 popped up in Port Macquarie for $18k - unregistered and barely running but decent shape, kept an eye on it for a few weeks and the price steadily dropped, $16k then $15k then $14k, that was the point where I was like shit someone’s gonna snatch this up! It was owned by a young bloke who had big plans but him and his missus just had a baby so smartest move financially for them but big gain for me. So 2 days later I’m towing a car trailer to pick this thing up. Roughly 2 weeks and $3500 later I’m cruising around Newcastle in my beat up R33 all smiles and dose noises! It only needed some basic shit to get it going, coil packs and air flow meter, electrical stuff and all fluids changed, 158k kms and running pretty good, nice smooth engine after oil and coolant flush - when I say coolant I mean it had been filled up with tap water, every gallery and heater element was filled with rust, 8-9 flushes later and still had brown liquid coming out but she’ll be right. The car was painted R34 Bayside Blue at some point but whether it was a cheap job or just not looked after is anyone’s guess, clear coat flaking like sausage roll.  Was rethinking my choices and contemplating life, had it up for sale for $22k - still cheaper than any registered R33 but got little interest, next minute I had an opportunity at work - 6 months overseas for good money, so that was a no brainer, fast forward again and here we are with a 50% finished project. Current Mods - 200ish KW according to butt dyno Was tuned with Apexi PowerFC EBC (old school Greddy Profec)  Stock turbo (more shaft play than a Tinder date gone right) 3inch turbo back Varex muffler  Aftermarket injectors of mystery size, Power FC showed 36% duty cycle at full boost so not behd good size Someone had good intentions but stuck with the stock R33 MAF so we had misfires at 6000rpm due to the MAF hitting 5.2V So far I’ve redone the entire interior with carpet form Car Mats Direct, new Seats and steering wheel from Autotechnica, also sound system by Autobarn (mainly Kicker) Also MCA pro comfort coil overs - Hands down best purchase yet, worlds of improvement over the tired 30yrold shocks Goals - 450kw/600hp on flex tune New paint job - Midnight Purple 2 Engine is at the shop getting rebuilt with forged rods a pistons, new valves and springs, ATI Harmonic balancer, Aeroflow 7.5L sump, rear head drain and oil restrictors as per oil control thread* and cam covers modded for larger breathers, other stuff I can’t recall of the top of my head Parts purchased and to be installed once the engine is done -  Engine loom from Wiring Specialties including these options: Haltech Nexus S3 R35 Coil pack conversion  PRP Dual Trigger kit Fan controller  Other Parts -  262 Kelford Cams Turbo - Hypergear ATR43SS3-ProS with T51R mod (whistly boi) 6 boost manifold (high mount) 50mm Turbosmart Pro gate (plumbed back for legal reasons) HKS Super Turbo Exhaust with High Flow Cat Custom 3.5inch dump and front pipe 1500cc Bosch injectors  Fuel Pump walbro 525 Haltech MAP and IAT sensors Haltech Flex Sensor Fenix Radiator with dual thermo fans LS1 Alternator Kit Oil Filter Relocation from EFI solutions and Cooling pro oil cooler Many other things sitting in my garage waiting for that engine to come back. Progress pics to follow -  
    • Losses have to be less with DC coupling. Provided the battery inverter has decent MPP tracking ability - which really shouldn't be a problem. It's not 2005 any more.
