slow down there seabiscuit. I have a zx motor in my datsun, yes it bolted in, the only thing you HAVE to wire in is the zx distributor which can be done with the E-80 Distributor upgrade diagram or you can Pm me and ill get some pictures for you and actually you will have to UNDO more things than wire them up, I.E. I removed my knock sensor because the 280z wiring diagram doesn't have that, and I had to change the thermostat back to the stock 280z's, but most important make sure you have the o2 sensor hooked up, your computer should adjust and have it leveled out, regardless of boost. Merry swappings.
