Description Hey guys got this BA E-Gas sedan to flog off for a mate.
It's got 170,000km, black interior, no options but has some Futura alloys on it.
It requires a VIV, as it has minor damage to the front (radiator support is fine). Would need a bonnet, bumper, RH headlight, RH front door and LH rear door to pass a VIV.
It drives fine, auto shifts well and motor is very responsive off the line, even compared to petrol variants.
For those who don't know they have pretty much an F6 motor in them but different pistons to run higher comp for the LPG. The motors themselves sell for $700-$1000+
Offering it here for $1900 before selling it elsewhere for a lot more.
Would make a great project. Could probably be back on the road for less than $4k if you've got the know how, and would make a great run around.

that's quite a claim, any proof to back it up?

Sorry, I'll correct myself - the F6 motors actually got the E-Gas rods. E-Gas motors have been around since the release of BA, but the F6 has only been around since late '04. These rods were then later used on XR6 Turbo from June 2006.
According to a few people who have pulled these engines apart, including reputable engine builders, the rods are pretty much the same as F6 rods, except have a press fit gudgeon as opposed to a floating gudgeon in the F6/XR6T.
For further information do a Google search.

Just to clarify the bending conrods on aftermarket BA gas issue. During development of the BA E-gas Falcon, two cars suffered from bent con-rods. We were a bit mystified about why. After a fair bit of investigation and head scratching we found the issue was caused by intake backfiring. Early prototype PCMs had an issue that gave an intermittent spark problem (long since fixed), that gave backfire issues on the early prototype E-gas BAs. Our investigation found that a backfire causes a pressure wave in the intake manifold that supercharges the next intake event, it also ignites that cylinder at about 90� BTDC. When the cylinder then tries to compress this, the in-cylinder pressures can rise higher than the buckling limit of the con-rod, causing it to bend. Even when we tried the petrol engine compression ratio we still bent con-rods. We went through quite a few engines working this out.
Why do AU and earlier engines not bend conrods? (I hear you ask)
Well we tested that too and they do exactly the same thing as the Barra engine however because of the 2 valve head configuration, they just don't get the cylinder pressure high enough, we did several hundred backfires and the pressure got to just below the buckling limit but never over.
So new stronger conrods were developed for the E-gas engine while the petrol engine kept the standard ones. Therefore if you fit an aftermarket gas system to a BA petrol Falcon, and it has a backfire for any reason, you may bend a con-rod and destroy your engine (we did). Of course not all backfires will bend a con-rod.
Good thread on FordMods..

Thanks for playing bud. I know my ****.
