I think..... it is a cast iron 4cil 1.8 turbo running 15psi/260bhp/7500rpm
it has don 65000miles and I wanted a rebore to 0.5mm with new pistons (I think I can have another 35000 out of it but because it is out and getting new gasket's and bearings for me it was the right time to do it)
my engine builder drilled out the third cilinderwall too much, he solved it by drilling it even bigger to 6mm (1/4") and pressed a liner in it redrilled to the correct diameter. but now I have one cilinderwall out of differend material on a hot turbo engine, am I right for not having any trust in this or is it a good way to solve things. (on a NA engine I feel safe to do it like this but I have no idea If it is right for a high output small engine where ther is lots of stress
please let me know what you think about it
thanks,rick
