rb25det automatic into automatic s13

[bobbyhill]

I ran across a rb25det automatic that was a good deal. It comes with motor transmission wiring and ecu. I was wanting to put it in my 1989 240sx that is automatic also. Can I still keep the automatic or do I switch it to 5 speed? Is there anything I can do to modify it to make it fit??
Thanks
Bobby

You can make anything work

I'm working on it now. I will start a thread in a few weeks to cover everything.
