turbotrana Member 2,586 Member For: 22y 2m 1d Gender: Male Posted 16/08/14 11:50 AM Share Posted 16/08/14 11:50 AM The spec'ed ring gap in the manual seemed quite small last time I checked, esp for a turbo. But it seems that the factory is running 14 thou on the top ring from memory and no bore scuff reported with it.However I rebuilt a E series drift engine (not my original build and just as a favour) which scuffed a few bores and the gap was around 16 thou. So when I rebuilt it I think I went around 20 or 22thou top and 22 or 24 thou bottom (cant remember exact). Being a drift engine I made it quite loose. And the engine gets heaps from the owner and runs very clean under high load. Nothing wrong with slightly wider ring gaps and the line of thought for the last decade is wider bottom ring gap than top ring gap.You will never loose an engine running a little loose but you will running a little tight.Make sure when you dismantle the engine you check ring gaps that the manufacturer used. Yes the gaps will be wider than the 14thou in the book but will give you an indication where you don't need to go past.

My engine builder recommended at least a 20 thou gap while the manual was much less. Went with the bigger gap and with e85 it comes pretty early as is.

I'm going to put some info into an engine analyser program and try some different combos 2 Link to comment https://www.fordxr6turbo.com/forum/topic/88984-piston-and-rod-combo/page/2/#findComment-1493002 Share on other sites More sharing options...
