Thanks Mighty I'll Pm you in a sec. The gaskets I was looking at are custom made by Cometic, and available up to .140"
Given the higher compression ratio to start with, I'd be looking at the .140" (3.5mm) gasket then as a minimum to bring it down to about 8.5:1 but looking at the cost (when I factor in shipping it'd be a £270+ gasket) think the more sensible option is going to be C20LET pistons or having the originals machined if there's enough in the crown of them to do that.
On the bearing thing, think I've answered my own question reading other folk's builds. Journals the same except XU5 big ends. Have found & snapped up some NOS Mahle VP2 big end shells for £25 which seems pretty decent & probably go with Glyco mains unless I hear different or find any VP2 mains cheap!
Thanks again, appreciate the patience given being a noob to turboing petrol engines!
