ED30 short write up.

[Teutonic_Tamer]

Actually, the major mechanicals of the Ed30 engine are the same as the standard GTI.  The only mechanical difference is a slightly bigger turbo, and a different boost pressure control.

The S3 engine is out on it's own, with different pistons, con-rods, valves etc.

If that's the case, would it be possible to upgrade an original GTI to the Ed30 engine spec?

Yup, you could either get the OEM turbo and ancillary hardware, or Oettinger http://www.rsdcars-uk.co.uk/Oettinger.htm also supply a larger turbo, as part of their 310PS package.  This was discussed at length in previous threads (probably titled Blufin  ).

Any clues on how much that would be vs. re-mapping....?

Ahhh, that is a much more complex question.

If you left everything else as standard, on a standard GTI, some remaps could potentially get you up to the 300PS region - but it would probably become quite undriveable, and certainly shorten the life of the standard turbo and recirc valve.

If you are looking for serious increase in donkey power, then you need to look at a range of hardware and software changes, including turbo, exhausts, hi-flo cat, freer-flowing intake system, etc

i think they've missed the point of the car!  and they got it wrong when they said its the same unit as the standard GTI! Its got more in common with the S3 lump!

Are you sure TT?

I thought that the ED30 engine internal upgrades are the same as the S3!

More info please TT... I've also read the same as Hurdy in several places.

I have read in loads of places that the Ed30 engine IS the S3 engine de-tuned a bit, hence the ease with which it can be remaped up to over 300bhp.  Also, I suspect the fact that the engine data in the Golf brochure says TBA because it is the S3 engine.

Read the end paragraph of the first page and into the second page on the PDF below. Yes, I know it is the superchips site, and not a VW site, but it adds "fuel to the fire" so to speak

Got to say, I think TT could be wrong here!

Well, I could be wrong - indeed, I think I was wrong, once! 

Anyhow, I now have access to offcial "press" sections of VAG websites (including Bugatti  ).  All the "official" speil is that of all the 2 litre FSI turbo engines, the 200PS, the 230PS and the 240PS are all identical in terms of engine internals.  However, the 265PS engine in the S3 has radically reworked pistons con-rods, valves, cylinder head, etc.

From the way I read and interpret all this, the Ed30 230PS, and the Leon Cupra 240PS have identical major mechanicals as the standard 200PS lump.  They just have the larger turbo, and the remote diverter valve, which the S3 also has.

The way I read that - it is ONLY the S3 which has all the uprated mechanicals, because in the same paragraph, they also quote the larger intercooler.  We all now know that the Ed30 has exactly the same intercooler as the standard GTI

Could you copy and paste relevent sections of what you have read please? Thanks

some of the German forums had posted info that seemed to confirm that the S3 engine and Edition 30 share short block assemblys (rumpfmotor in Deutsch) - they seemed to think that this included pistons, conrods, etc (in much the same way that the previous S3, TT 225 and Cupra R shared much the same stronger engine compared to the ordinary KO3/KO3S 1.8t)
