The ED30 has :
- 230bhp Engine which is more like a detuned S3 engine, with K04 turbocharger and other bits and bobs
Wrong. The S3 has many unique uprated components which are NOT shared with any other TFSI engine, including different pistons, cylinder head, PCV, and camshafts. So the Ed30 is NOT a "detuned S3 engine".
Now now Mr TT, that's a bit unfair 
, please read my post again slowly ......I said MORE LIKE a detuned S3 engine .... not that it WAS an actual detuned S3 engine. And I was comparing it with the standard GTI engine.
My post was based on many articles which describe that the ED30 engine has been strengthened internally as well as having the K04 turbo. VAGTECH and Volkswagen Driver mag also concur

Although I think that TT is right 95% of the time and I do as a rule accept his opinion which is borne from years of experience and a lot of knowledge... there are occasions when he gets it wrong.
And I hope you will accept when I do get things wrong, I am always willing and able to accept that I was wrong. However, with the 2.0 TFSI engine variants, there is a considerable amount of wrong information. Look on tyresmoke and the general concensus was that it had an alloy block - I pointed this out, got viciously shot down in flames, calmly challenged them to provide hard evidence to prove me wrong. They stated it was in the official self study guide, again being very hostile to me. Again, I asked them to link to it, and bided my time. Guess what - they all went quiet - no link - no proof - no nothing. So I posted a link to the said document which they had so agressively claimed I was wrong - suffice to say - the block is cast iron.
All I am trying to say is that there are many others out there who are more than willing to accuse me of being wrong by kangaroo court, yet do so without any evidence of their own - but sadly, because someone has already labeled me as being wrong - mud sticks.
I do have thick skin - but I ALLWAYS post the truth/facts honestly and to the best of my abilites. But to some, the truth hurts, and some can't take it when the truth may 'jeopardise' a potential sale.
The guys at JKM have seen various engine parts for the S3 and Ed30 as well as the GTI and they have confirmed to me that the Ed30 engine is indeed different in many ways to the GTI and has more in common with the S3 engine with which it shares many parts. I am being vague here about the exact details of what it shares as my memory fails me, but suffice to say that it corroborates what VW Driver magazine wrote.
If JKM told you that, then they are being extremely misleading!
The standard GTI, the Ed30/Cupra, and the S3 engine all share many, MANY common parts -
there are way more parts in common, than there are different parts. I am not, and never have denied that there are 'differences' between engines - but whenever anyone makes the claim that "the engine in an Ed30 is the same as an S3" or similar types of statements, then I will always disagree, because as I have repeatedly stated, there are certain, uprated components which ONLY THE S3 ENGINE has. Maybe you'd like to ask JKM to confirm the part numbers of the pistons, cylinder head and camshafts. And then ask them to advise you of the actual technical differences.
