It seems that there isn’t many pistons to suit the G180Z these days - the engine hasn’t been made for nearly 20 years, which I guess doesn’t help. GCP sent me an email yesterday saying so, and reporting that the Chrome-Moly rings I was looking for are no longer available. That means I’ll just have to deal with stock steel rings, and upgrade the pistons later when I supercharge. Since the engine hasn’t actually cost me that much, I might go to a 4ZE1 or something like that when I supercharge it, giving me a 2.4lt engine with slightly more modern components.
