Twin Webers Certified in NSW?

go to someone who does'nt give a crap, did'nt bother the guy that done my blue slip. I don't think young cops know anything about carbies anyway!

In a word - NO !!!!!

A1980 Escort has to comply with ADR27A, and twins will not pass ADR27A if the car is to be tested correctly.... (see your own compliance plate...)

I went down a similar route 15 years ago and ended up getting an early 76 Escort instead of my 79, as it only has to pass ADR27 which is a lot easier. It is one of the few "real" legal twin carbed Mk2 Escorts and has its Engineers certificate to prove it. Talking to my head guy who has most likely kicked the can now, he told me that there are requirements for HC, CO, NOX and a few other things, but in a nutshell if you can possibly get the hydrocarbons down (unburnt fuel) the NOX starts going too high as the fuel is not burning properly.... I am not an expert in this, but technically twin carbs worth any sort of performance gain at all will not meet ADR27A. How many twin carb cars were sold in Aus after 1st July 76 do you see (Other than Alfettas which were nto tuned for power). Domolmite Sprints were not imported after that date and a number of cars manufactuered after that date were no longer imported into Aus after that date...

having put cossie sierra and skylines through shed tests in the past,it is both expensive and difficult to pass.they need the car for two days in order to check emmisions on cold start then do a simmulated drive.all your carbon cannister.pvc fuel tank breather,rc breather must be in new condition.

I've had an efi Hardware setup on my car for 10 years, highly recommend it.

It cost me a lot more than that back then though. Damned economies of scale!

Sure do Craig. Apparently they run well in combination with a Wolf ECU.

Wooligan, you have a good point regarding EFI, nice setup and I can see the benefits.
My situation is a little different. I have a mate offer me his engine, includes twin webers, extractors, flywheel, clutch etc. A complete running engine for a quater the cost of an EFI setup.
This engine has a bit of grunt, so I want to put it in the mk2.

The engine has a "Repco Gold Star Engine" sticker on the rocker cover. Does anyone know much about these Repco rebuilds? It could just be a sticker, but when we looked under the rocker cover, we found the cam was not standard but couldn't determine what it was or what else had been done to the engine.

Another question, is there any air filters that help muffle the induction noise? or does more muffle equal more restriction? I want to avoid the air box solution. [x2x]

Not sure what grind the cam may be but the Golds Star engines were a bit more performance focussed than stock rebuilds. Repco used to be in the business of mass engine reconditioning and this is probably one of those.

I used to work as an engineer at ACL's (formerly Repco) piston and ring plant where pistons were cast and machined for Australian and some export motors including locally produced Ford, Holden, Toyota and some truck motors. They made OE and aftermarket pistons with the aftermarket stuff always being technically more advanced (in terms of design and material composition) than standard 'factory' parts (that were made at the same site). A bit off topic, but the chief engineer at the time was one of Jack Brahbam's F1 engineers, so the joint had a bit of a performance focus.

So short answer, I wouldn't be surprised to find other interesting goodies in the engine as well.
