Gas - you gotta love it

Hi Jomah,

Depends on the model (year). My bros has LPG on his 2004 Paj, cost 6mths ago in Adelaide was $2450, (S.A. with only Federal grant, it cost him $450)
Mine is 2006 Model Challenger (also have a 380 on LPG) so the after 2004 only fully computerised systems are used and only on certain makes and models, cost for the Challenger was $3800, so the main thing you will have to find out is what kits fit your vehicle.

Hi Jomah,

This reply might repeat because this is the second attempt - the original might turn up from hyper-space any moment now.

I suspect that because of the twin grants available here in WA, and the huge demand for conversions, the prices are a bit inflated.

The base model which works through the carbie is around $3000 so is basically free after the grants. I bought the 'you beaut' computerised injection model. It's easier to switch between fuels - just push a button - and it automatically switches to petrol for cold starts and then changes back to gas after a couple of kilometres. The cost was around $4400, so $1400 cost to me. You have to pay the lot up front then reclaim the grants. I also had a cylinder lubrication system for an extra $100 which may not be necessary, and I also paid a bit extra to get the spark plugs changed while the manifold was off because changing plugs on an NM is a big deal.

I was spending around $110 per week on petrol, that will reduce to around $46 so $64 per week saved, so break even would normally come around the five and a half month mark. However, as I am off to the Pilbara in June I would expect to break even after about 4 months or a bit less.

The tank is 68 litres, which even with the slightly reduced power would have to cover more than 300kms.

They take out the folding third row of seats in th NM, cut out the floor and put in a new one slightly deeper. It fits in very neatly. The filler fits alongside the petrol filler. It means that to use the third row of seats I either have to leave them set up all the time, or leave them in the shed when not needed - it only takes seconds to slot the seat in. It is illegal to use the third row of seats when the cargo barrier is in place so spur of the moment use was ruled out anyway.
