Alright, so I just want to get this straight: Is the bottom end of an F6 Typhoon engine the same as an egas engine? What are some of the differences? What's the difference internally between a BA engine and a BF engine and even an FG engine?

Cheers, Gab

After June 2006 they all run the same thickness rods, gas motors have fixed gudgion pins. Also compression ratio changes between the various series
