I dont have a problem with lpg,had my daily drive converted some 4yrs ago and to be quite honest the performace,fuel consumption remained the same ,unless you were told you would think it was running on petrol.
The biggest problem would be mounting the extra tank,as we all know Zeds are a little short on space in the boot,the other alternative loose the spare wheel,and see what size tank could be fitted.At the time mine cost me £1300,which i got back on fuel saving,On the six cylinder i would think around £2000 for a decent installation.
Hmmm got me thinking now,and thats dangerous :wink:

like you say i think the only place for the tank is where the spare wheel goes... would be interesting to find out if its been done on a zed..
im sure youd get your money back after 12-18months also...

A Dutch forum member had it done a couple of years ago on his 2.8 coupe at a cost of Euro 2,500.00.
He said that he has a round tank, 60cm across and 25cm high, in the boot. (no photos I am afraid)

He did not mention how much lpg he could fill up, but in his last post on the subject he said that he had driven 380km on 40lt of gas, which was similar to his petrol usage but obviously a lot cheaper.

He also said that he had not noticed a difference in performance using lpg, but he did change his spark plugs more often than before.

PS, these people in the UK have done it.

I had been thinking about it as well after my dad converted our Corolla to LPG (I must say it's rather brilliant as a workhorse and daily driver now that it's so cheap to run).

I took the car to a specialist and they had a tank that would fit the diameter of the spare well, but the tank would be sitting too low for comfort and he was worried about it getting scraped over bumps etc. Anyway he said the only realistic solution was a cylindrical tank in the boot, which would take up at least half the space, so I said no and bought a scooter instead for my daily commute to work lol :P

I'll be keeping the Zed for special occasions only I think. And to be honest I'd hate the engine bay after an LPG install, it would just look molested :D
