How does the Alusil sleeve will hold in place? There is no difference how to insert a iron or alusil sleeve. Cause the sleeve has to be bigger than the bore. The block is heaten up and the sleeve is cooled down.
Kolbenschmidt just say that there is an option to rebuild one cylinder like this and they have the spare parts. They do not recommend this and the don't care about the small wall between the bores. That is always the knowledge of the engine shops what works and what not. In other engines with thick walls I would agree there would almost be no issue when just sleeving one cylinder.

I’m glad you were able to find something that worked for you, again I’m really not interested in going back and forth over the opinions/options of individuals here on the forums. I’m interested in those who’ve done it, or are interesting in doing it. Not those who decided it wasn’t for them. I’ve considered the risk, researched, and consulted. The process for sleeving a single cylinder with very little material between cylinders is outlined, whether you agree with it or not. The shop I am working with has quite the portfolio. Porsche, BMW, Benz, Audi, marine and automotive racing engines, and a very good understanding of alusil blocks and the required processes and tooling. Like I said, if it works out I’ll drop their info in this thread after I have put some miles on the car.
Thanks for the input
