hmm i feel sorry for the bloke who started this thread... seems to be somewhat hijacked lol!

as for profits in regard to gas kits... i'm not sure about other gas installers... however where i work is a general mechanical workshop... gasfitting is just one of our services... and its probably our lest profittable service ... however you provide people with a gas conversion at good competitive rates and give them good service... we'll usually get thier business again later on down the track servicing thier car!

What no more tough talk?...pls continue

If the pre rebate conversion cost was $1200-$1500 then after the rebate was anounced the price went up to $2300-$3000 for a basic conversion?

You do the maths sparky....If they could sell them @ 1200-1500 at a profit.....well?

So a subsidy of up to $2000 appears magically you can't get the same job done for under $2200...in simplistic terms they jacked the pricing accordingly.

Result: oppotunity for profiteering and wasted taxpayers dollars, now did you comprehend what I suggested as a better policy re: fuel-gas subsidies, we'd all win every time we gas up instead of companies and corporations gaining through a crap policy.

The policy is flawed and has been recognised as such...so it is going!

Now that's as simple as I can put it....

Now as I said a few posts back Sorry for the hijack, Now hows that gtr conversion going?

i asked for proof. so wheres your proof? Do you have any evidence to backup what you are claiming?

you say that the installers profit from the government rebate? i'd like you to prove to me how they do when i paid the full $2300 for my mothers car and then get the $2000 back directly from the gonernment?

Not here to talk tough to you. just wanna know where you get your information from.

so, wheres your proof?

Well this seems interesting. very keen to see the end results, good or bad. i drive an BF falcon ute for work which is dedicated gas. its got the dual tanks on it, i think they are around 100L for the both of them, it gets around 470-480km/tank. that is usually fully loaded with building supplies, but one thing i do notice is it's lacking in torque compared to petrol car. when u are going up hill or something like that, u have to give it a boot full to get it moving.

what type of gas set up do the falcons have standard?

anyway good on you for trying something out fo the ordinary. even if u dont get your rebate back, u will still be saving in the long run of all goes to plan.

Wow, I seem to have missed a few things for not checking this topic for a few days! Glad to have fostered a bit of high current discussion.

Seriously though, I don't want to go into the price issue, wasn't really the point of the forum. I was more interested in proving that it is possible and usable, or if a total failure then at least a warning to others to wait for the technology to improve.

Those who know me know that I love my GTRs. I may not treat them like I love them, but that's another story.

I'm 2 weeks away from getting back on this project. Unfortunately my motor turned out to have other damage which required attention first, so I'm part way through a rebuild to be completed before finishing off the gas project. When it's all up and running I promise to post the results.

To be noted, this is not going to be a top fuel dragster, but rather a road car with regular GTR power. The system is quoted to be good for 260 kw, so let's say 250kw allowing for exageration. I'm happy with that. If you wanted to go higher, it is possible, but it would require a 3rd injector bank and a second set of injectors plummed in. I would also think that the vapouriser would be a limiting factor and a second unit required.

That being said, it all depends on what you want to do on lpg. This is a piggy back system which takes control of the injectors, shutting them down when on lpg and using it's own ecu to inject the lpg. There's no reason you couldn't run 2 different boost levels and manually switch to petrol when running higher boost. There is some compromise as the piggy back ecu does not control the timing, but that wouldn't be too hard to balance out, and if using a standard ecu, there's no reason you can't use the limp mode program to have 2 different timing maps.

While I'm on it, check out the program that the you use to tune it. It's looks pretty good. Uses standard serial interface and you can make the cable or buy it for about 30$

Just to update this for everyone, Vapour has just become usless. lol On the 20th of august we are fitting Liqiud injection to cars, Capable of any power and a very simple design with no converters , and

6 injectors only wich are capable of any power lvl,

it will be about 200-300 more than vapour but its well worth it,

currrently been converted, ( by rnd department,) xr6 turbo completely standard and no tuning picked up an extra 18 kw due to the discharge cooling .

also beeing done supercharged 6.0 ltr, with IMPRESSIVE results. well over the 400rwkw mark ,

these kits are the way of the gas industry,

cheers pete.

certainly isnt new... weve tuned a few liquid gas cars running a myriad of ecu's.. haltech, autronic etc... yes it is the way of the future but there are still limitations on injector size vs horsepower, some of the big horsepower stuff needed twin injectors per cylinder. What brand system or components were used on the supercharged 6litre?

Our vz Sv6 we had for a few months had gas injection on it from new.... 2004.

so you modify the manifold to accept another set of injectors. any limitations beyond that? what sort of hp/cylinder are the current range of injectors capable of delivering?

the thought of a big power RB running reliably on straight liquid LPG makes me all happy in pants

      You just need to remove the compressor housing, not the entire turbo. I would not be drilling and tapping anything with the housing still on anyways.

      Mistakes were made, my R34 Story

      By Kinkstaah · Posted

      So, I put my boat on a boat. First of all, I'm going to come out and say it. Why is Tasmania not considered a holy goal, an apex that all road-legal modified cars go to, to experience? This place is an absolute wonderland of titanic proportions. If people are already getting club runs for once in a lifetime 30 person cruises to Tassy then I've never seemed to see it. It is like someone replaced the entire place with an idyllic wonderland for cars, and all of the people living there with paid actors who are kind, humble, and friendly. Dear god. After doing a lap of almost all of the place I've found that it's a great way to find out all of the little things that the car isn't doing quite right and a great way to figure it all out. All in all, I drove for 4 hours a day for a week and nothing broke. I didn't even need to open the engine bay. This is by all means a great success, but it has left me with a list of things to potentially address. I also now have a 3D printed wheel fitment tool which annoyingly hasn't got any threads in it to actually assemble it. I might be able to tape it together to check the sizing I actually want to use, but it'll likely involving pulling the shocks out to properly measure travel at least at the front, and probably raise the car while I'm at it, at least in the rear. I scraped on quite a few things and I'm not sure how else to go about it. I was taking anything with a bump at what felt like 89 degree angles. And address those 10 other tasks. And wash the car. God damn it is dirty. And somehow, the weather was perfect the entire time - And because I was on the top of Mt Wellington it turns out it was very much about to freeze up there. I did something I typically never do and took some photos up there in what must have been -10 and the foggy felt like suspended ice, rather than mere fog. If you own a car in Australia, you owe it to yourself to do it.

      R32 gtr transmission strength, billet plate

      By cosline · Posted

      Hi, I have a r32 gtr transmission. Does any of you guys have an idea how much power it will hold with the billet center plate and stock gearset? At what power level and use did yours brake with or without billet plate? Thanks, Oystein Lovik

      Spotted on the street....

      By Rezz · Posted

      Saw this replica police car based on a Mitsubishi Starion XX parked next to a 'police box' (it's literally a box) in Hirohata, Himeji City in Hyogo prefecture the other day. It's owned by Morii-san who is a local Mitsubishi Starion enthusiast. According to a local radio station blog post, he always wanted to make a police car himself based on ones he saw in his favourite Manga comics.  As it's illegal to modify a car to look like a police car and drive on the road, Morii-san tried many times to get permission from Aboshi police station headquarters nearby. They refused initially by after they got tired of that they granted him permission. However, the car can only be displayed on private property and obviously can't be registered as long as the police livery is present. The car was completed at a cost of 1.5 million yen (US$ 10,000) in addition to the car cost. A location was chosen outside Hirohata Police box where the car can easily been seen from the street. Morii-san has two other Starion road cars, both widebody GSR-VRs.
