... and when you're unable to deliver that encore... well then you'll have no choice but to refund

Who says I'll be unable to deliver ??? (might have to pop a little blue pill though ...

)

It's the pill that makes him "THINK" he's a stud

OK guys. I've just had a word with the guy who may be able to do the job.

The good news is that, without me having to tell him anything he advised me how changing the turbos may be possible without actually lifting the engine out. I don't know if this is common knowledge in the industry, but on the face of it it sounds like a good start him knowing.

He was also aware of the items that need to be changed along with the turbos, and knew the difference between hybrid K03's and K04's.

But, just to make sure that he does not commit himself to any work that is either beyond him... or simply not possible, he's gonna have a word with his VAG guy (who works across the road from him) and will get back to me with further news... and hopefully a very rough cost for the job (I asked for labour cost only as I'm assuming that who ever wants to do the job will supply the parts???)

He mentioned something called "gack"? or "Gtech". Some kind of engine management/mapping system. Anyone heard of this?

Finally, I exlpained that if he's up for it, someone from here will give him a bell to talk technical issues.

Fingers crossed by all those who may want to go down this route..........

I "FEEL" you're correct there Mark ...

I asked on the Buehn Engineering forum about the shaft size that Doug mentioned as a weakness of the K03 - I must have lost somethingin my tranlation of Dougs post to my question as Jacob replied that teh K03 and K04 share the same size shaft.

Maybe the K04's just spin slower so the overspin in the event of a boost leak isn't so bad? (Really taking guesses no). Can anyone comment with some know how?

This is all getting very interesting. The later K03 has better oil ways also.

I think it is the boost leak issue that will be the main killer of the turbo's.

Yes, it's the shaft speed that's the issue. A K04 compressor wheel does not
have to reach the same RPM to make the same boost as the K03 wheel. This
is also affected by the aspect ratio (effectively the volumetrics of the compressor
housing which will be the same in a hybrid in any case). Your big problems are
oil starvation and overspin. Later cars had an updated bearing housing which
had larger oil galleries to help with the oil starvation issue. It's also good to use
a fully synthetic oil and change regularly. Most of the failures discussed on AW
seem to be caused by using dino oil.

So are we saying here that going hybrid K03 with the better housing and reduced shaft speed is a sounder option than a straight out of the box K03?

Just spent the afternoon at MRC - we had my car up on the ramps and you can see why the engine-in-situ turbo-swap is virtually impossible (and why Doug didn't want to risk doing it that way in the end!) - there is just NO room to manouvre whatsoever ...

@ Graham: Doug confirmed that the K03 and K04 shafts are different sizes ...

Nice one Mate and thanks for the info.

Well for me that wonderful idea is pretty much over then

. If it is engine out it may as well be KO4's IMHO.

Snap. Jolly good thread though!

Yes Paul - shame, but there it is! K04s for me too as and when I (a) get £2.5K spare, or (b) I'm forced to put it on the plastic 'cos the fvckers went POP!
