ED30 and Audi S3

[bacillus]

Was he Ed30 or Cupra?   

Neither, he has the standard US FSI gti that he upgraded to a k04 before replacing his cams.

Ah, rite. 

[MAT ED30]

Doesn't have a bigger intercooler or oil cooler?

Larger ic

So I guess the next question is, if I do the K04 upgrade to my current stage 2+ GTi how would that compare to a stage 2+ ED30?  Would the performance be the same? 

[gobbleplease]

^^^^^^  i believe the only differances between the s3 engine and the edition 30 are a strengthend block, intercooler and possibly cams, going big turbo ko4 on a gti seems to get less power on the gti than the edition 30 some believe this is due to different cams which makes me think that the s3 has the same cams as an edition 30 ?

If the ed30 has beef'd up internals, means to me that putting a k04 on a weaker strength block and pistons will only eventually lead to one ending.......

Steve p red mk5 ie Vwr old car was a ko3 car turned to ko4 with ed30 cams but is now on an ed30 mtr

There will be a certain degree of overengineering in the gti engine to and despite there being a fair few ko4 conversions now ive not heard of any problems with the ko3 block or internals yet, although ive no doubt the edition 30 is going to cope with the extra stresses better.

There have been numerous head gasket failures on the strengthened engine when people have been running stage 2 + though.

If i was going to modify by adding a ko4 i think i would do it on the newest tsi engines , they seem to be a lot better , have better flow and make more power.

[Jussa]

Well now I'm totally lost 

I was hoping that the upgrade would give me the same power as an ED30, but after all this banter I guess I need to sell the car and get an ED30 or Pirelli

DanGb big turbo'd his Tfsi Sport Leon (200hp / Gti engine) He did end up getting fancy Rods by IE and  pistons though.

Tbh ive been a 2.0t owner for a few years now and check the forums reasonably regularly and ive never heard of a head gasket go yet, ive heard of two engines going pop but no gaskets pinging.

I saw one go bang at castle coombe that wasn't a forumite. Car was wrapped in Gulf branding.

 I doubt it. My Ko4 converted since 50k has 101k on the engine now and runs perfect and never any issues.

Using the same dyno for comparison Revo stage 3 Ko4 conversion vs Ko4 stage 2 + give the same average bhp, in fact the ko3 engines seem to hold the power longer up the rev range.
