Hey mtnickel, sorry for the late response.  I had already ordered a RB25DET and it should arrive tomorrow.  I am on a pretty limited budget and wanted to make sure that I actually finish the car first. (Complete restore)  Then probably add some money after she is running and driving for a year or so.  Thanks for the input though.  I am in the process of stripping down the engine bay and prepping for the RB to arrive.  In a bare minimum, get it running sort of scenario, can I run stock brakes and or suspension?  I have a 1978 280Z that I am going to strip for parts.  It looks like the rear end is a good swap.  Any other specific parts that I should swap over?  thanks for any help of info.
