I am going to stick my neck out slightly, that's a full 2 litre engine in there.
It would be worth trying to find another, Ibiza GTI or MK3 GL and comparing them. The downpipes look to be MK2. Maybe the probe is missing and the folk doing the conversion weren't bright enough to appreciate that fact.

I find this quite amusing. Most people with Australian delivered mk2 GTIs want the 2.0 bottom end and a more free flowing exhaust.
That twin catless downpipe is the graus. with a good manifold ( it would appear that you already have the mk3 twin outlet manifold because you have 2E motor ), it's near as makes no difference to extractors.
Not sure about fuel consumption but leaky injectors?
edit: What's the part number on that ecu? it could actually just be a golf mk3 harness... :?
Yes, I've noticed the many similarities to the 2ltr used in the MK3 GL GolfQuote:

Just to confirm, there is absolutly NO area along the exhaust in which a oxygen sensor could mount into:frown:
Part number for it 037 906 022 CLQuote:

A MK3/MK2 hybrid:confused:
If the injectors were leaking badly, I think you would find it hard to start. I wouldn't be concerned about the 4 electrode plugs as long as the heat range is correct.
I think if you were to get hold of a MK3 wiring diagram you could find out the colour of the lambda probe wires and see if you can find a plug with them in.
I had a MK3 16V in the UK and it was carp on petrol, barely ever getting to 30 MPG. A friend had owned one and he often saw 40 plus on the motorway at 70mph. Sometimes up to 50 on a back road run.
Anyway, sometime a couple of months after I bought it, I went to install some suspension and found that the lambda probe was just tied to the heat shield over the exhaust. The PO had de-catted it and not bothered to put the probe in the exhaust. I fitted a cat I had in the garage and immediately got another 10MPG everywhere. The ECU would have been seeing a massively weak mixture and tried its hardest to richen things up.

On a cold morning my car takes no more than 3 seconds to start.... Id imagine that doesn't count as hard starting
Just went out for another check around the engine bay and FINALLY found the plug that the O2 sensor harness would plug into! (atleast I think so?)
Feel rather stupid that I couldn't find it before, but ohwell.

The wires going to the plug
http://www.vwwatercooled.com.au/foru...DSCF0408-2.jpg
It was hinding around the back of the 4th inlet runner on the manifold, had 4 wires going to it, so a 4 pin plug?
May get a quote from an exhaust shop to see how much it would cost to weld a bung for an O2 sensor to sit in, into the exhaust.
Just had a sneak around GAP, all MK2 O2 sensors are either 2 or 3 wire. MK3 O2 sensors are 4 wire:confused:
It looks pretty obvious to me that this car has had a 2E conversion. That 2E engine was never offered anywhere in the world in the mk2. In the process, they have put in that custom made exhaust and left that 4-pin lambda plug hanging.
It also explains the other wire plug you found in the scuttle tray, and the alternator is probably the mk2 one because of the ease of re-wiring.
If that actually is the correct ECU for that engine, then its gonna be a very confused little computer without that oxy sensor in place and like Gav said, is feeding loads of fuel in coz its getting no reading.
Remember, this car came from South Africa, which raised my suspicions of it being standard/factory immediately. I've seen quite a few imports around from SA, all of them were "tinkered with".
You should be able to sort that out with a standard 2ltr mk3 lambda??
Cheers
Thats what I hope but heres the plug end of a 8V 2.0L MK3 O2 sensor connector plugQuote:

The problems is immediate,
Differant pin set up with that pin on the end so far from the others... with a tab in the middle.
And I can assure you thats its a very confused computer!
15+ ltrs/100km aswell as occaisionally coughing black smoke on cool start ups
I also have no clue what that 2 wire plug in under the rain tray, any ideas?
Thanks:bowdown:
PS: Im also curious as to what will happen when I plug an O2 sensor into a ECU that hasnt had one for a LONG time......
I can assure you that is a very confused little computer!
15litres per 100K aswell as coughing black smoke on cool start-ups.:rolleyes:
I wouldn't necessarily go off the pic because sometimes they are inaccurate.
Give your Brissie hsy branch a call and see if they can sort one for you.
I'll have a look at my girlfriends mk3 2ltr when she gets home to see what that plug is too mate.
There shouldn't be any issues with the ECU once you plug it back in to a lambda, thats what it was designed for!
Good luck!
