I would definately go with MS, even though NismoPick just spent all that time putting in the Z31 ECU, haha
That should be all you need though. And as for using the J30 coil packs.. I have no clue, you would have to ask somone more knowledgable.
And I would definately use DIY, great costumer service!
ALso, Why are you swapping your motor into a 240Z, I thought you already put money into the ZX?
