The EB Ghia lpg injection? I had it converted back in 2004, paid out of my back pocket before government rebates existed! Expensive, but very worth it. I had my torana converted to an amos ring setup, that really sucked but gas was 0.20 cpl to 0.30 cpl so it wasn't that bad...

40mm is the ideal size for all round drive-ability and is pretty much the industry standard size.
When you do manometer testing of the signal strength from the ring there is no restriction upto about 3500rpm and it produces enough signal strength from about 1000rpm to draw gas from the converter.

Bigger mixers will not have enough signal strength to draw gas at low rpm and you normally end up with a rich idle to cover the hole.

You'll never get a 50mm mixer to work properly, 45mm is really pushing it on a 4L engine.


If you want to try getting big mixers to work start with a 55-60mm mixer and modify it by adding a booster venturi to it. The changeable main venturi from weber carbs could be modified to work well.
You'll just need to do some research about the correct placement of the booster.

But i would only be doing it, if it was more about the learning process then the actual end result.

If would be easier, and possibly cheaper to swap to a gas research setup at the end of that trial.

i've got a vapor injections system at work that my be going on my AU, i just need to check whats in the box as i'm told it was originally ordered for a Hyundai Sonata V6. My suppliers are pretty sure it would work when I have the right ECU for it.
