Newcastle

Had these fitted a couple of months ago with a set of pedders coilovers.

Congrats on the conversion, I have not had time as yet. I have found that when I do run it on petrol every couple of weeks the tank has to be over half full and the VSC disappears, below half a tank of petrol it seems to stay on.

Have you had any loss in power ? The gas injection systems are far more advanced than the previous mixer gas setups, but are also significantly newer and more expensive. Going with the injection system is the best solution for modern day cars, as it doesn't cause a significant performance or efficiency loss, and is generally more reliable. Essentially, the old-style system mixes gas with air through the air intake and basically "tricks" the ECU into thinking it is still injecting and running the engine normally off petrol. The gas injection system basically replicates the existing petrol injection system and uses its own ECU and sensor hook-ups, thus the reason for the significantly higher cost. You will also probably void your warranty (if you have one). As was mentioned by Rocketeer1 however, do remember that the properties of gas make it quite harsh on engines that are not specifically designed for it. In addition to using thicker oil, keep in mind that gas also has very little lubrication properties and can therefore cause some damage to valve seats and other internal engine components. Generally there are additives that are supposed to keep this at bay, but you would have to check this with a qualified installer. This is just some general information I found when considering a conversion myself, but I personally decided against it due to the increased wear-and-tear factors and high costs. Also not a major fan of having a compressed tank of gas behind me or losing boot space or my spare tyre. The best places to go and find the advantages and disadvantages would be a reputable gas installer and a good mechanic. The system I have has its own injectors and the 'gas' ECU piggybacks off the main ECU, as for harshness I disagree, gas does not create carbon deposits, carbon creates wear and dilutes oil, the aurion engine is all alloy thereby has stainless inserts fitted to the head this negates the need for an upper cylinder lube kit. Yes i have lost boot space but only at the back of the seat, my spare tyre is still in the same position, as for a tank it has built in safety valves. There is a newer system liquid injection that is around $1500 more, has better economy and claimed increase in horsepower due to the fact of liquid gas is injected into the combustion cylinder creating colder denser air for combustion.

My coolant gauge sits half way either on gas or petrol, I had a falcon on gas for 10 years and ran 15w-50 semi-synthetic did 340000kms it still runs perfect for the new owner with no oil consumption at all.

Have you had any loss in power ? No noticeable power loss, dyno would give true figures.

I had my ZR6 converted to gas injection in Oct All going well with the conversion, my only issue's are that the gas filler is crammed into the petrol fill point( I did not want an external gas fill point, have to just live with it 'maybe a little re-engineering' ). I have an issue with the VSC lights coming on whilst using gas, I am hoping the manufacturer will fix this soon as it is a programming issue. The VSC lights go out when I switch back to unleaded. The all important usage figures: NB These figures are not from driving with economy in mind, I enjoy the 200Kw of Toyota power and sports mode 393km using 41.22ltrs = 10.49lt/100km around town running 414km using 38.81ltrs = 9.37lt/100km Sydney/Newcastle trip with around town running So for around $25 (Gas @ 0.59) I am doing 400km (Based on 10.50lt/100km) Where as I believe petrol at 9.5lt/100 (petrol @ 1.2) would cost around $45 for 400km Conversion will pay for itself in two years ($4000 Conversion less $1750 Rebate) Cheers Hope this helps

No endorsements of this web site at all but a good comparison page I found when I was deciding what to buy is http://www.drive.com.au/car-comparison again my personal preference. Hope this helps, Cheers

I payed 130 plus GST 2 months ago, they are for a set of 4 (front and back) from Toyota in Newcastle. Very easy to fit follow the directions and you should not go wrong. Cheers

It is the spark plugs, Flush brake Fluid and change cabin filter, a good website I found to compare prices for service was fixedpricec****rvice.com.au but I am in no way recommending any repairers listed just a good comparison site, Cheers

Thanks to All, I purchased Autoglym products and cleaned the interior today, very nice.

Another question for all, the ZR has leather interior are there any good recommendations for weekly cleaning/preservation of the interior?? Cheers

All going well with the conversion, my only issue's are that the gas filler is crammed into the petrol fill point( I did not want an external gas fill point, have to just live with it 'maybe a little re-engineering' ). The petrol door does not shut properly because of the gas filler, this should be fixed Friday and the first matter discussed as to the best approach. I am having the 1000km installation check for the gas system at the same time to ensure correct operation.

Update on Conversion. The trip computer does not recalculate 'Distance to Empty' or 'Ltrs/100' based on what is in the tank? My current distance to empty is 0km with a quarter of a tank of petrol, having used primarily gas. I will have to fill with petrol and gas so I can start to log the km's. Too excited last week when I got the car back to think of logging details, just wanted to drive... :)

Had my 2007 Aurion ZR6 converted last week. All going well, no noticeable loss of power infact the 'lag' seems to be gone when taking off from a standing start, it is vapour injection. I can keep updating if you would like.
