I have a 70 MkII and thought I had a rod knock. I pulled the 8rc out and bought a 78 or 79 corona with a 20r and 4spd manual trans.
After I pulled both motors. I found that the torque converter on my MkII clunks around when I shake it. Is this normal for these cars? I have had 300zx's, 240sx's, cadillacs and none of their torque converters have done this in fact they dont make any noise. I think this could be the knocking I was hearing when my car was running!
There are too many differences in the 8rc-20r to make this swap worth while. The carb and intake mani are on the other side thus making he kick down for my auto trans nearly impossible and not to metion the mounts would require some massaging. I would like to put my running 8rc back and drive the car unil I find a good 1st gen rx7 and use it to swap the rotary 5spd into the MKII.
Does anyone know what automaic transmission came in the 70 MKII? I believe it to be a a30. But am not sure. Also does anyone know where I can get another torque converter?? I have looked online and the local parts houses dont sell them.
Here are a couple of pics of it as it sits.
