GTR conversion to LPG

[Mandingo]

please please dont do it on an R34, there is only so many left buddy

in my opinion LPG GTR = sacrilidge.

What sort of depreciation does 25,000 km p.a. result in?

<{POST_SNAPBACK}>

Is your car an investment?

Mine is for driving.

[browny]

It's not an investment, but it is an asset.

If you are going to try and justify this exercise on economic grounds, then I want to see the math behind it.

Depreciation is a real running cost, just like fuel, maintenance and finance costs. IMO doing a f uckload of km in a performance car seems to be a good way to waste money.

[psybic]

Its true, performance car and saving money don't really go together. I think you would be better off on LPG than Petrol if are doing alot of kms though... and some people might like to drive a GTR for example instead of something else.

Some people like opera... isn't my cup of tea either, seems like a waste... but each to their own I guess.

Also, the resale value is only realised if you actually sell the car, some people may decide to keep the same car for 20+ years... In this way, building a car just how you want it, would be a significant advantage.

I'm 22 and have owned 6 cars. I can tell you, changing cars is expensive! If I found the right car to suit my needs perfectly in the first place, I'd be alot of $$$ better off. That is what someone is trying to achieve here, the perfect car for what they want... Not for track days.

You could convert a GTR into LPG......

Or you could just buy an excel.

I can't see why anyone who was capable of obtaining an R33/R34 GTR would convert it to a LPG system. Pretty sad endeavour IMO. I'm with Thommo...imagine telling people that you own an LPG run GTR. Embarassing.

And if you are REALLY doing this for the environment, then you're a hippie and I don't like you, can't stand the thought of a GTR with peace symbols and flowers painted on it.

Good luck fella, I’ve considered doing the same to my GTR. Don’t let the negative comments put you off. You can really only be accused of lateral thinking...Did you receive any information back from Bill Campbell of Gas Injection Technologies about the "Stealth" injector system? I would assume that with a power fc the "stealth" injectors could be tuned to suit.

Maybe that could be my numberplate.... SACRLDGE

PS... it's not oing to be a GTR as such.. either a Stagea RS4 or 260RS.

Maybe I'm nitpicking.

Not Yet... it's been a week... I'm hoping for a reply though.

More research tonight...

ON THE PLUS SIDE

Prices. My opinion is that we are heading for more international instability in the future (just my opinion), and the fact that Australia imports most of its petrol, but produces its own LPG will have a bearing on prices in the future. From an industry point of view, there is a lot less risk investing in Australian LPG than investing in Middle Eastern oil, and hence the price gap will increase in the future.

ON THE MINUS SIDE

The GTR is an icon; a halo car for the entire Nissan range. To make a swap to LPG based on running costs would just be sacrilige. Sorry dude, it's just wrong. Added is the fact that the cost would run into thousands of dollars, so the system would take probably two or more years to pay for itself and start saving you money.

CONCLUSION

If you want economy, buy a Honda Insight and convert to LPG. THAT would make for some cheap running costs. 3L/100km @ 40cent/litre. Slow, cramped, uncomfortable, but cheap. A GTR is purpose built for performance. It is not an economy car. However, if you do decide to go through with the conversion, good luck to you! It will be truely unique, and I will be devastated when my petrol chewing GTS-T gets eaten up by an LPG running "taxi." I can't wait to see the first Enzo or Pagani converted to LPG...

I also clock alot of kms on my GTR (it's my work car). LPG is an interesting consideration given the stupid fuel pricing.

I suggest that people doing the 'sacrilidge' line need to go buy all the GTR's left if they are worried (start a new religion and get a fund together). Personally I think you all missed the point.

What a life to spend endless kms in nothing but a great sports car. Instead of having some puss bucket nanna 4cyl to do 99% of your driving in with the GTR only for weekends. I tell you I can't go back. I seem to recall a few other guys I know in the same boat, notably Ant from X-speed's now 900rwhp daily driver. It's a good thing if you can afford to do it and if you need to go LPG to make it more affordable then I say good for you!....end of rant.

I couldn't help but notice that our website was quoted, so I felt compelled to get amongst it

LPG is not just a cost saving excercise it is a high performance fuel, and in my opinion the only fuel to run on a turbo charged engine. Have you ever heard of a decarb being benificial, LPG cleans out the entire engine and dramatically reduces engine and turbo wear. After 10,000 ks the oil is pretty much as clean as when you put it in.

When LPG is injected the engine power is equivalent to or more than petrol and the power delivery is smoother due to the higher octane rating.

I totally agree with all of the negative press that LPG has obtained over the years - for example Nissan spends several million dollars developing an engine and engine management system so it runs sweet and Jo from down the road installs a LPG system that he put together from a few parts that worked ok on the family commodore..... need I say more, but if you spend a S**t lot of money and put in a H**l of a lot of work believe me LPG runs Bloody good!!!!!

Bradkazz,

Im assuming your from the profire group. Could you provide the forum with an update on how well the Laser Turbo is running on the gas injection. Maybe a run down on the mods that were required to make it work. Also could you provide the power output and fuel economy its achieved.

Nice input.

bradkazz, Any chance you can help me out with installing LPG on the Stagea (Series 2, RB25DET Neo engine)? I'm hoping to pick it up next week.

[bradkazz]

Yes I am one of the designers of Profire engine management. The laser, which is actually my car, is running multipoint gas injection and direct fire ignition. The engine is a Jap spec BPT (134KW version) which is basically the same as the later model TX3. It is producing approx 175KW @14 psi and gets about 10km/L. Drivability is basically the same as petrol except that the power delivery is smoother and the gas gives more bottom end torque. LPG injectors, 1 per cylinder, replace the gas carby and the LPG vapourises is a high pressure type ie the gas is delivered to the injectors at about 20psi. The laser runs straight LPG so I installed the gas injectors into the factory petrol injector ports.

I/we are willing to help anyone who wants to run LPG especially turbo owners.

i used to have a mazda rx3 turbo that run straight lpg . went faster and harder on lpg than it ever did on petrol loved the running cost as well . i would consider converting my skyline to straight lpg one day to all those thinking of it good on ya. dare to be different dont just be a sheep following the flock

Thanks for the info Bradkazz,

I understand one of the issues with LPG injection is the reliability of the injectors themselves. What injectors are you using and how reliable have you found them?

Also, could you lay out a rough cost and parts guide for retrofitting a gas injection system.

I’m surprised at the economy you’re achieving. Am I correct in my observation that it is similar to the stock car running on Petrol. How is this achieved with LPG having a significantly lower calorific value?

hey brad!

welcome to the forum, its qik_30x from ford laser here!
