Lpg Powered Gtr

I know you think it looks crap, but the volume of the tank you will be able to fit under the car will limit the milage you can get out of a tank. Cram it into the boot space and be done with it, may help you get some decent endurance out of it

[twosixpowah]

will be keeping an eye on this thread!!! Got any more pics?

[benm]

Remove the factory fuel tank, cut the spare tyre area out and mount a round tank in there.

[dead32]

so your willing to more then halve your available lpg tank size, because it doesnt "look" good in the boot?

do this^^

the system looks alot like the one i got on my jackaroo.

[chris_r31]

you will regret having a gas tank the size of a milo tin..

who cares if you want the tank to be hidden, people gonna no its on gas when they see you fill up at the servo..lol.

a maltese mate of mine did a gas conversion to his 97 ford fiesta,lol got the biggest tank to fit what you call a boot in the car.. fills up once every 2weeks, and drives just for the sake of driving..

doesnt feel any slower and f**k the money saving is good...

benm, that's what I was going to do. Done this already on the race car and there's heaps of space, more than the boot would allow. Should get and easy 65L under there. Good for about 450km.

Not trying to hide the fact that it's on gas. Will fly the flag loudly and proudly once it's all working, just don't like how much space the tank takes in the boot, and more importantly, I want to be able to say with confidence that I haven't lost anything by going to gas. maybe a little bit less power, or a little bit less range (that would be hard given the limited range on petrol). Still want to be able to fit the golf clubs!

[Duncan]

but he needs room to put rb26s in the boot still

looks like you had a damn busy day mate

That's it for this week. I'll get back to it next weekend. Have to pull the motor out, not because of the lpg, because my turbo problem turned out to be a piston ring or valve problem so I'm going to rip it apart this weekend. I'll take some photos of the space under the car with the tank out and the spare cut out and post them on the weekend.

So you are going to cut out the spare wheel well and throw a part of the tank in there? cool, but where to for the spare tyre? Not beign problematic, i think its hell cool that you are throwing gas on it. Just if its going to be a daily driver, what are the legalities for chopping into the spare wheel well?

[arep3]

wouldnt that be a structural part of the car?

[urtwhistle]

you wont be filling up every 100's i get 330k's out of 55lt's and removing the petrol tank is a stupid idea................. i already looked at that. there is no tanks unless u went custom that can be fitted in there. so do like i do, and dont carry a spare tyer unless your going out of the metro area.

[haw001]

Never carry a spare anyway, In the last 10 years I've had a flat once, and even then I only bothered with the can of goo to get me to the service centre. We've got 5 LPG falcons here at work and took the spare out of all of them because of the space. Never had an issue as technically you are not allowed to change a tyre because of OHS unless you've taken a driving and maintenance course. We just carry the patch in a can

A picture will explain better, but with the petrol tank gone, the spare wheel well just hangs down taking up a lot of space and making all the space around it useless. You cut the spare well out and weld in a flat sheet in it's place. You end up with tons of room under the boot and it's all flat. The only thing in the way is the muffler and it's all the way on the left hand side.

There's enough room for a decent size lpg tank, or better yet, 2 decent size tanks. I'll find out the cost on the twins today.

You should go have a look on the LS1 forum before doing this - they have a liquid injection system up and running now using multiple injectors, increase in power over a petrol car and 20% less gas use than regular LPG system. Price is supoosed to be only slightly more than the sequential systems.

I thought about getting the floor cut out of my 34 but then the price just seemed to go through the roof. only problem is that it would like a SLR5000 with a drop tank. if you end up doing it and end up successful i might look at it again. then i could tune it for dedicated gas instead of ultimate 98.

Not true. A lot of performance LPG specialists do the same and have multilple 'scuba-type' lpg cylinders (all connected and making one single tank) located in place of the original fuel tank (just like snags on a BBQ plate).

[coakman]

By the way, does everybody know there is currently a $2000 grant for anybody who fits an LPG system? You have to pay the cost of the conversion up front (regardless of whether you go straight gas, or duel fuel) but you then receive the $2000 refund. You may end up being out of pocket only $500.

Add that to saving of $1/litre and it starts to look pretty damn attractive, eh?

Here's some more interesting bedtime reading for everybody:

Build yourself an appleseed reactor, start making bio diesel. and pay 25c/l for your methanol you will need...

and have a car that smells like a fish and chips shop when running.

this has no relevance to lpg or petrol.

but i like your idea of doing this to a gtr.

[haw001]

Just got back from the LPG equipment supplier and piggyback smaller tanks are certainly an option. Tanks are not much different in price, but there is the cost of 2 mounting brackets and about $70 for some sort of balancing valve.

And yes, I'm definitively after the $2000 rebate. Big factor in getting this done.
