Here are some facts on LPG (Australian specs)

Calorific value---50 000 kj/kg(petrol around
47 000 kj/kg)
prefered a/f ratio 15.7:1
boiling point-- -42deg cel
relative density as compared to air--- 1.5
octane rating---- up to 110
prefered comp ratio 10.5:1
expansion ratio from liquid to vapour-- 270 times
spontaneous combustion occurs-- 430-440c
Here are the pros for lpg

cost saving in fuel used
cost saving in engine repair(less wear)
cleaner burning(less combustion chamber deposits)
reduced emissions--co,hc and lead
no pilferage of lpg
safer than petrol(if system is leak free)
smoother power from engine
easier starting (hot or cold)
As far as cylinders go, yes the carbon steel ones are quite heavy but there are still stainless steel ones around that
reduce the wait heaps.
more power with a turbo charged engine is achieved
thru being able to match the a/f ratio thru to high boost (up to 30+ lbs boost)without the aid of any electrics(computer
etc)
we have done it on several vehicles and stunned the guy at the dyno by recording very high horsepower outputs.
enough of the classroom hehehehe

Hows about someone starts a sister club calling it datsun 1200 modified or anything so we then have a place to either add
or store pics

The setup im using is a hybrid system using a century M6 converter with a modified atmosphere side (to take boost).I used the original FJ20 throttle body and machined a
gas venturi ring that slides inside it.
The metering is done with a century barrel valve which was adapted to the bottom of the throttle body which discharges thru to venturi ring.
like i said this is a hybrid system and there is a bit more involved in getting an idle and transition circuit to give the correct ratio from idle at atmos to high boost.
depends where you are on this planet as to what type of equipment is available .
Where you from Bob????
sorry to boar you all with gas dribble but after a lot of years of getting this together even im starting to get excited!!!

Hey didnt want to start anything when i said that the coupe was the go....and i admit that UGLY was a bit over the top hey its a datto
and there all mint!!!
Im sure all of us have a soft spot for the project we are working on and think its worth the effort and time to bring them back to life

anyway does anyone know what ohmerage the fuel sender runs at .(1200 coupe)
I have to convert my LPG sender to run at the same range any ideas?????
cheers
Dave

Yes i have fitted an LPG system to my datto.
Im still in the process of inventing it .
Most of it is fitted but have not got to the stage of starting it up
yet.
Im a licensed LPG fitter and do it every day as a job (mechanic by
trade).
LPG has a lot of advantages of petrol when used in a turbo
application.
I will put some pics up when im a bit closer to starting it up
cheers
Dave

the style you prefer is up to you but over in perth the coupe is the go(got one myself)and the sedans are left to be used as bush bombs (i think the sedans are ugly) but its up
to the individual

Let me know what you need to know
i have a fj20 det in a 1200 coupe so i could have what you need
email to davgas@bigpond.com

Hey what about the FJ20 turbo the best of the lot !!!!!

MERRY CHRISTMAS EVERYONE

.
