as far as my research has gone, the 6m lower end is the same as the 7m. couldnt find info on the timing setup. the pistons are definitely different, but couldnt find the comp ratio either.
i know all the parts for my jdm 7m had 6m stamped on them (rods, crank) so id say aside from the pistons, youd prolly be solid.
