^^ Huh?  that makes no sense at all.

About E85 not being as available as LPG? I can't speak for other states but Adelaide only has 7 servos that provide E85 and once out of Adelaide there there isn't anything. Once your becoming low on fuel you can't just drive into any servo like you can with LPG and refuel. 

Oh my mistake .. i read your comment as "E85 is not available as LPG ..." 
 
E85 really isnt the answer for a part time car or something that sits around a lot.  Driven everyday and refueled every week maybe, but ethanol blend fuel simply doesnt store well.  It separates which means the fuel potency will be very different as it is burned which effects your tuning, add to that it is hygroscopic and corrosive as all hell.
 
 

Sorry to hijack the thread.
Gdub, I have spoken to an engineer briefly who has given me the ok for a duratec with itb conversion so long as there is a cat.
He is hopefully issuing a cert for the cage, seats, etc next week.
Ill try and get something on paper from him then before I collect anymore bits.
I'd appreciate to hear of any past experiences you may have though.

Not sure what state you live in but in Vic the car will have to have an emissions test and the emissions will have to meet the standard of the engine not the car.  To put it really simply although probably unlikely, you couldnt put a ZETEC in a MK1 escort running carburettors.  If the car had a pinto or a kent you could have the carburettors because the car is pre ADR27A but if the ZETEC is out of a 2010 focus then it must meet 2010 emissions.
Sure it will have to have a cat on it but that is only part of it.  The test is done running with an exhaust gas analyser sniffer up the pipe

In in Victoria,
I was also under the impression that you had to meet the emissions standard for the engine not the car. When i spoke with the engineer he seemed to think it was quite achievable though, (he didn't make mention of an emissions test which supprised me) so I'll have to see what he says on Wednesday.

It is the engine. If the engine was out of a 2010 car, its a 2010 engine.

Have a Zetec in my mk2 with twin jenvey TB, built in 1980 passed ADR27a getting sign off next week by engineer. Did take 8 hours of dyno time and 2 epa tests but finally got it passed.

That pretty much hits the nail on the head.
 
You need to meet the ADR standards of the engine or vehicle body, whichever is later. At no point does the ADR state HOW and under what configuration of engine components need to be used. The crutch comes in proving ADR compliance, and that requires time and money in order to meet the standard(s) and prove you meet them. I note throughout the entire thread that no-one has mentioned just how much each of the EPA tests cost in order to prove you meet the required ADRs. Anything can be achieved if your pockets are deep enough.
 
Best option. Dedicated Liquid LPG Sequential Injection. But that's another discussion...

I'm not sure it does.. The car is a 1980 so ADR 27A applies either way. But according to everyone here (and common sense) he should have met emission standards of the engine, which would be far more onerous than just ADR27A.
 
I'm not disagreeing (I mean they said mine was ok with no test) but it seems to me its not as black and white as I was hoping.
 
 

Andrew, that isn't right when it comes to emissions.  The 'which ever is later applies'
