Piston Ring Gap For Turbo I6 Engine

[turbotrana]

Has anyone got access to the FG factory manual to check what piston ring gap Ford suggest for the Turbo I6 engine.

I was looking at the BA BF Factory manual and it only had ring gap for the Non turbo I6 engine. And even for a non turbo engine the recommendations were tiny gaps compared to what I usually use and certainly too small for turbo engines.

N/a ford I6 ring spec

According to factory Ford manual top ring 8.4 to 14.4 thou

bottom ring 14 to 20 thou
