You could drop an e-mail to Andy Ross in the states, he's been there and done that as far as coatings and anodizing of cylinders and pistons.
I just keep away from aluminium on these parts, and try to stick to cast iron for both bore and piston, although if the size is right I use the tube from inside a shock absorber, because this is round, parallel, and highly polished.

Thank you for the input Pete. I'm aware or this fact, actually I had to specify the thickness of the oxide layer (in micrometers :o) to the company who is doing this. So I think this will be done quite accurately. And also for this reason I will fit the piston to the cylinder, so it doesn't really matter if the bore is a little bit smaller.

Ian, I was in touch with  Andy Ross. He provided the articles he wrote about these engines.
