I've been researching how I would go about building my SC M62 for more boost ( I know an M62 isn't an S62...). Nikasil is a proven motorsports technology and porsche's been using it in their TT cars for quite a while, and the issues with it have been caused by too high sulphur content in fuels (no longer an issue).
Peter's recent issues with what appears to be cylinder ovaling due to the sleeving process (my guess, I have not done any direct investigations), and the head gasket issues David has had with his sleeved engine (less heat transfer due to the sleeves) makes me believe that a thick Nikasil coating with the appropriate Nikasil friendly rings (JE and others make them for their forged pistons) would work with less headaches...
Anyone enlighten me on what I'm missing?
