Well might as well give this a stab.

Since everyone knows the government and its plan for LPG in cars.

Does anyone know places in Sydney to have their car installed with LPG?

And if so prices would be good. Mates rates would be good too >_<

Prices have probably doubled since the government's announcement. :)

Been thinking about this for the Corolla.

What are everyone's ideas?

Thanks

one of the guys here just got an LPG conversion for a v6 commonwhore. I think it was $4k or something.

What I can't get over is the fact that the LPG technology they convert your car to use was designed back in the 60's.

LPG systems are a joke. why you want to convert a decent EFI car to one with a half arsed carby set-up is beyond me. just to "maybe" save a few bucks and spend your time driving around in a backfiring, hard to start car that smells like fart.

at least then your lame trdy plate might make a little sense as every time you drive past someone with think the person walking in front of them just filled his nappy.

haha, man i am cruel.

2k of fuel prolly lasts a long time...

hmm

actually, with petrol prices these days and the inevitable increase predicted with the coming months and if you fill up for $80 a tank (bp ultimate) a week it would take roughly 20 weeks to spend that money. that's less than 6 months.

my question though is will converting to lpg decrease a car's performance? ie. skylines in particular (apart from the increased weight of the tank)??

The general rule of thumb is that you lose around 5% power going from petrol to LPG. Not sure if its the same for turbo cars, since most people who do it tend to run NA engines.

If it burns cooler at a higher octane, you can always offset this by running more boost.

Saw an article in some HPI or Zoom mag. I only briefly read it though and can't remember exactly what it said.

But the gist of it went:

There's a workshop in Queensland that's actually developing a proper LPG system.

The owner of the shop has converted his BA xr6 turbo to run on petrol and LPG but with proper injection and engine management (different to the normal, "lets blow lpg down the f**king intake pipe and take a brand new engine and make it run like it was designed in the 60's").

After tuning the car apparently makes more torque down low, and switches to petrol seemlessly up high in the rev range to give better top end, or something.

Freaky. I remember putting gas a couple of old v8's I owned. The peak torque area moved UP about 1000 revs.

Also I don't think unleaded takes you 30% further, LPG is something like 8-10% less efficient without making other changes to the engine, eg ecu and cams.

I thought it actally burned hotter than petrol which was why one of the age old drawbacks of it was burnt out valves, particularly on engines designed to run on leaded fuel without hardened valve seats.

There was a guy on the forums a while ago building up an engine in his line which he was going to run on dedicated LPG. He said they were looking at 10-15% increase in power due to higher octane rating of gas. Sounded like he had done his research, but i dont' know a whole lot about it except that i've seen it on dual fuel systems and it runs like a dog.

However i would be interested if they proved it would run nicely, and save a bit of money (considering LPG is almost 1/3 the price of petrol now)

$80 tank x 20 weeks = $1600

apologies for not being clear with the calculation. the reason i estimated this price is because the money it will cost to fill up a tank will increase over the next 6 months.

anyways, i agree with what shif-tea..

      After market rear camber arm adjustment

      By Jarsky · Posted

      This. A 3d wheel alignment is like $120...just take it to the shop. Since theres probably multiple adjustments that need to be made after changing something. Mine has front/rear lower arms, traction rods, tension rods, camber arms, toe arms, front upper arms, hicas kit, sway bars and coilovers. I measure from the edge of the bolt holes on the originals and set the same length on all the adjustable stuff to dial it as close as I could to OEM. Took it straight for alignment; it didnt feel right at all...after alignment, it feels perfect. Similarly i've just changed the springs on another car; and I still needed multiple adjustments to bring it back in spec.

      R33 Fuel Pump & Brakes after alarm swap

      By Jarsky · Posted

      Its a well known brand in New Zealand; its a rebrand of the Rhino RAV3.  I don't know what the wiring difference *is* between the rev.1 (installed about 15 years ago) and rev.2; but as you say I would think its reasonable that it uses the same immobiliser relay circuits. I had a look but couldnt see a similar harness; but didnt move things around since I didnt want to mess with it   It was one of AVS well known Authorised Installers; I spoke to AVS themselves about it but theyre unsure hence seeking advice more so from the skyline community who are more familiar with the actual car and its wiring. Im in Auckland; but the installer is on the other side of the city so hes very reluctant to come back to even look at it to confirm something isnt connected into the wrong wire.  I dont want to drop the name since they *did* do a really good job for the most part. Everything is very tidy and he fully replaced all the alarm wiring, all the sensors, the wiring to the door motors, installed a switch which was never installed in the first place...really happy with the alarm install itself..just not this one issue. We all make mistakes, if it is the alarm, I just want my fuel pump getting proper switched, fused, power as it was; without having to shell out for an auto electrician to switch a wire and tell me it was the alarm.

      Blue/grey smoke after idle

      Even with the piston at TDC there was room for it to drop, but I don't think it can drop fully into the cylinder, the problem you have is that you need something pushing against the valve to hold it up so you have enough room to put the new stem seal on and the spring etc.  I used compressed air only because putting rope in the cylinder seemed a bit risky to me, I know people have done it countless times before like this. Overall it's a pain in the ass job. Honestly you'd probably be better off taking the head off because the risk of dropping something in the engine and the finicky-ness of it all is very stressful. If you are going to attempt it though i 10000% recommend a 36050 valve spring/keeper tool. I had both the traditional lever type and after doing 1 cylinder it was absolute pain to get those valve keepers in place, even with 2 people. That 36050 is amazing, you do have to push hard to get them in place but it works perfectly almost every time. Back to my actual issue I think my engine is just tired and old and the rings have gone bad. The comp numbers (cold, no oil) were: Cyl 1 -129psi Cyl 2 - 133psi Cyl 3 - 138psi Cyl 4 - 137psi Cyl 5 - 157psi Cyl 6 - 142psi   Cylinder 5 and 6 having the most carbon on them.

      Who did you have do the installation? I actually know someone who is VERY familiar with the AVS gear. The main point of contact though would be your installer.   Where are you based in NZ?
