A direct injected LPG engine would make crazy power, run cleaner, and be able to run some pretty silly CR's.
The only other problem is that LPG doesn't have any lubricating properties that gas has on the valve stem, so you get much more wear on an already stressed part. There's pro's and con's to both.

too true MAG....bit difficult an engine to sort from here really due to the M103 being mechanical injection only
That's why IM injector ports were bunged. To run it basically as a carb (how it's set up now). Also, for ease of putting back to petrol (gas in US). Liquid injection would be nice but very expensive & uses different cylinder & everything else btw. This is way over my budget & intension for car
A mixer indeed yield good results but I believe it is the tune
ie AFR that is the concern here. This engine has suffered heat/corrosion. No brainer. Just what went wrong I won't know fully til' rebuilder has a sqiz. I believe it ran too lean amongst other things.
Rebuild was an abortion full stop!
On a brighter note, I have sourced a brilliant LPG man near where I live so, will be talking to him soon. He does the Gas Research conversions down here. After rebuild, he can get it right from there.

Yep, he resorted to EBay auction
I knew what I was getting though, other than the rooted engine of course, that was a bonus
Whereabouts in Melbourne are you? I'll have to catch up when it's all ready to roll
