Turbo 250 on LPG - Ford Forums - Mustang Forum, Ford Trucks, Ford Focus and Ford Cars

I have been trying to explore my options with a turbo conversion on my falcon.
A way that has been bought to my attention (thanks Rollin) would be to utilize a straight LPG setup.This would be mmore economical than a petrol setup and has a higher octane level.

What i would like to know is how does the intake manifold work when going to straight gas?
Would my current Redline manifold be used?? Or is something else fabricated?
Would the intake be completely different for a turbo? like the XE on autospeed? There isnt much info on the manifold on their website.
I havent actually seen a gas system on a carbied car before. Is a normal carby still used?

Would it be possible to use an existing LPG system and make adjustments to run a turbo? Thus saving a lot of money.
Would i still need an aftermarket computer like MOTECH etc to run the LPG setup?
Would the static compression still need to be lowered to around 8:1 with LPG?
Ive heard rumours that you dont really know what you are getting with LPG fuel quality wise is this true?

If i could use an existing LPG setup with maybe a few carb adjustments this would be so much cheaper than converting to EFI and buying a whole new fuel management system.

If anybody can shed some light on this for me or give any advice whatsoever it would be greatly appreciated.
Thanks
Dan
Sorry for the long post.

The "turbo LPG" topic is too large to fit into a post here really but email me at tonyk@chariot.net.au if you want to. The gas stuff you need is less than 500 bucks from the wreckers.

Yeh the turbo gas setup also has an advantage of being EPA legal becuase of the emissions.

Also can LPG run with NOS??

Will the crank and rods from an EF/L fit in a 250 crossflow? On performance forums a guy reckons they can.

And will a rear Axle from a E series car slot straight under an XF with drum brakes?

Thanks again guys.

the e series diff wont fit as it is 25 spline not 28 which is ran in xfs but you could probably change the spline and it might work not to sure though

Dan, they can use your existing manifold or GRA (Gas Research Australia) has an XF EFI type inlet manifold specially suited for str8 gas, have a look at www.gasresearch.com.au for pics of the inlet manifold, as for the diff, the internals will go into the xf housing, but the diff will not slip into the car, get urself a disc to disc rear end out of a ghia and go to any diff place and tell them that u want 28 spline axles in it and woteva diff ratio ur after.

Some people think that in the late run of 4.1's (in the early 90's while the XF ute was still being made) had a casting number starting with 87DA instead of 84DA and supposedly the journals were the same as the EA-L but I am yet to see any evidence of this, so I'd leave it at an answer of NO as I doubt it would be worth the hassle to find one for the minimal gains available. Would be easier to get an EF/L engine and drop it in with some XG engine mounts.
