hey guys I am doing a conversion on my ute and im putting in the 4.0 L motor and basically everything out of the falcon! I just want to know the difference between ba - fg series, as I am not going for the turbo motor ( due to crazy conversion price) I wanted to know which would be better out of the n/a xr6 models? and which one would work better if I turboed in the future?? also... are the new 6 speed auto box's compatable with say...a bf series n/a xr6 motor? do the n/a fg, bf xr6 motors use the typhoon internals also? if you guys get my drift as to what im asking throw some info at me! I am all ears as I dont quite know all the stuff about these motors yet! thanks, anthony.
