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..

      Duncan's V37.......race car?

      By MBS206 · Posted

      Even more fun, leave all the ADAS stuff plugged in, but in different locations, hopefully avoid any codes!   And honestly, all these new cars with their weird electronics. Pull all the electronics out Duncan, and just shove an aftermarket ECU and if needed a trans controller in, along with a PDM. Make it run basic but race car styled!

      To follow up a question from earlier too since I had the front bar off again (fking!) This is what is between the bumper and the drivers side wheel And this is the navigator side, only one thing but its a biggy! So basically....no putting coolers in the wheel arches without a lot of moving other stuff. Assuming I move to properly race prepping this car I'll take that job on and see how the computers respond to removing a whole bunch of ADAS modules

      Duncan's V37.......race car?

      By Duncan · Posted

      So I prepped the car for another track day on Wednesday (will be interesting to see coolant temps post flushing out and the larger reservoir, with a forecast of 3-14 being 20o cooler than last time I took it out). Couple of things to mention; since I am just driving the car and not taking a support vehicle, I took the rear seats out and just loaded the back up Team Trackday style. Look at all that space! To cover off removing the rear seat....it is weird (note the hybrid is probably different because it wouldn't have folding rear seats) Basically, you remove the lower seat base, very similar to a r series but it is a clip that pulls forward to release the base rather than it being bolted down. Easy Then, you need to remove the side section of the rear seat on each side. There is a 14mm head nut at the bottom of the side piece, the it slides upwards off a hook at the top to release; you also need to unhook the seatbelt from the loop at the top. Then the centre piece is weird. You need to release/fold the seats forward with the tab in the boot on each side From there, there are 2,x12mm headed bolts holding the rear of each seat to the folding bracket, under the trim between the rear seat and the boot (4x christmas tree clips there, they suck). The seat is out but you can see where the bolts attach to the bracket

      As discussed in the previous post, the bushes in the 110 needed replacing. I took this opportunity to replace the castor bushes, the front lower control arm, lower the car and get the alignment dialled in with new tyres. I took it down to Alignment Motorsports on the GC to get this work done and also get more out of the Shockworks as I felt like I wasn't getting the full use out of them.  To cut a very long story short, it ended up being the case the passenger side castor arm wouldn't accept the brand new bush as the sleeve had worn badly enough to the point you could push the new bush in by hand and completely through. Trying a pair of TRD bushes didn't fix the issue either (I had originally gone with Hardrace bushes). We needed to urgently source another castor arm, and thankfully this was sourced and the guys at the shop worked on my car until 7pm on a Saturday to get everything done. The car rides a lot nicer now with the suspension dialled in properly. Lowered the car a little as well to suit the lower profile front tyres, and just bring the car down generally. Eternally thankful for the guys down at the shop to get the car sorted, we both pulled big favours from our contacts to get it done on the Saturday.  Also plugged in the new Stedi foglights into the S15, and even from a quick test in the garage I'm keen to see how they look out on the road. I had some concerns about the length of the LED body and whether it'd fit in the foglight housing but it's fine.  I've got a small window coming up next month where I'll likely get a little paint work done on the 110 to remove the rear wing, add a boot wing and roof wing, get the side skirt fixed up and colour match the little panel on the tail lights so that I can install some badges that I've kept in storage. I'm also tempted to put in a new pair of headlights on the 110.  Until then, here's some more pictures from Easter this year.

      R32 GTS (RB20DE) Injectors Replacement

      I would put a fuel pressure gauge between the filter and the fuel rail, see if it's maintaining good fuel pressure at idle going up to the point when it stalls. Do you see any strange behavior in commanded fuel leading up to the point when it stalls? You might have to start going through the service manual and doing a long list of sensor tests if it's not the fuel system for whatever reason.
