Welcome to my world of pain brett
Ok from what i have been able to gather over the years is this:
Vapour carb setupCarb/ mixers
You can use a single technocarb, otherwise you will need a twin setup, either impco 425's or Gas Research.
Tank
2 std tanks(single outlet) or 1 dual outlet tank both with twin lines all the way to each of your 2 vapouriser's that you will need for you power levels.
This setup would prob cost $3500ish, with the 2k rebate = $1,500 not bad coz you will prob make that back selling your petrol goodies that you have on at the moment. Power should be similar if the engine is built for LPG.
I would prob go the technocarb on a single plane out the bonnet coz you can
or get a twin carb manifold (easy for chev) and go twin impco 425's
Down side:
Car smells like poo, but you get over that when its $30-50 to fill. Torana looses that lovely petrol smell, but you can always put some in a water sprayer and give the interior a once over
better yet use it as a cologne.
Vapour injectionTank situation is the same, prob only 1 maybe 2 injection vapourisers, but the main difference is you need an ecu and this is the killer and why it cost more! Same situation as going injection with petrol really, better economy than LPG carby being the biggest draw card and same power as petrol. ALso all the other goodies that you can do with an ecu if you care for all that.
You would need to tap injection bosses in your current manifold and run a 4 barrell throttle body, or get a aftermarket injection manifold that you like the look of. Again not to hard for a chev!
Price 5-6k??? rebate again so 3-4kish minus your petrol gear 2-3k????? not really that bad seeing you could drive it every day then
AND that was the price i paid for a GRA carby setup when the rebate wasn't around!!!!!!!!
Smells less like poo as it has better control over a/f ration
Liquid injectionSimilar setup to vapour injection.
Now we are talking
supposed to be only slightly more than a vapour injection($500ish) and you get better again economy and MORE performance than vapour injection AND petrol.
Tank is differnt setup, only one needed as it has its own pump built into it, so no vapouriser coolant hose sh$%t every where. Just one line from the tank to the regulator then into the fuel rail -> injectors.
Not out yet but will be soon
By the time your engine is done it should be fine.
Hopefully i will be getting a liquid setup as if your gonna spend that much might as well pay a little more and get better economy/power again.
Ecu would be good for you application bret as you can have dual maps setup eg. economy for cruzing and power for the drag etc,
But in saying all of this you do lose something not really sure what it is, could just be a bit of the cars bad ass character with LPG, the smell, the carbys ruff sound nothing will be the same as a muscle car on petrol spitting out raw fuel etc.
Hope this helps you bret
