  1. Looking for a MegaSquirt setup for my '77 280z. Would prefer a complete setup including wiring harness. Thanks!
  2. Hi all, So I'm currently in the process of switching my '77 280z to carbureted with the AZC manifold. It's my first project and pleased to say that everything is coming along quite nicely. I'm now ready to begin wiring everything but wondering if it's possible to simply use a 240z harness? I'm deleting the AC so don't require any of those wires, and I've obviously eliminated the need for FI cables as well. Thoughts or suggestions would be greatly appreciated! If it's possible to simply use a 240 harness it'd also allow me to clean up the engine bay too!
  3. I'll just chime and and say ditto -- thank you for these! I've spent countless hours staring at this diagram and it's been probably the most invaluable resource in my build. Thank you!
  4. Gotcha! Okay, so hook the distributor wires to the mini-junction? I assume the wires then run from the mini-junction to the transistor ignition unit? Thanks again!
  5. Hi all! Got a couple rookie questions for you... I'm reinstalling the original wiring harness on my '77 280Z and need some help ID'ing a couple items. (1) There are red and green wires running off the distributor. On a wiring diagram it seems to suggest that these wires run all the way to the passenger firewall and connect to the transistor ignition unit, however, I don't believe this is physically possible given the length of wire. Any thoughts on where it may connect to? (2) Perhaps related, albeit a separate question, what is this mini junction with red and green wires connected to i
  6. Before/during/after dashboard resto. Took a couple of weeks of trail and error, but happy with the results. I could certainly spend *much more* time on the dash but considering I only have 1 day a week to work on the car I think it'll suffice for now!
  7. Hi all! Looking for two parts related to the AC system... (1) The AC line that enters firewall and into evaporator. (I believe this is the line that ultimately connects to the receiver/dryer). (2) AC pressure switch. (I believe it connects to the side of the receiver/dryer?) Thank you!
  8. These guys completely rebuilt the sending unit for my '77 280z. http://tristarrradiator.com Family run business, super quick turnaround. Not surprisingly, he said he does lots of Datsun rebuilds and seemed to indicate that he could build brand new ones as well. I'd suggest touching base with him and see what option he has available.
  9. Sounds good! I'll give it a try this week!
  10. Thanks SRRTz! So plug #1 and substitute a straight fitting for #2? If so, that's what I planned on doing but NPT threading (1/4" for #1 and 1/2" for #2) doesn't quite work. In other words, I'm only able to turn each maybe one or two rotations before the threading stops it from going in any further. On the other hand, maybe one or two rotations is sufficient if I use some Teflon tape on the treads?
  11. Thanks ritrebor! - #2, the larger inlet to left of circle receives the heater hose from the firewall. I'm just not sure about the smaller connector circled in red which I assume is the "external bypass" in diagram? - #3, sounds like I'll just leave the rubber caps on that came with the radiator since I have manual tranny. Thanks again!
  12. Hi all, I hope this is the right subthread for my question. I've been referencing this diagram pulled from another thread, but I still need some help identifying the following items... (1) What does this outlet connect to from water outlet housing? I'm assuming it connects to the intake manifold, but since I removed the original manifold and installed the AZC manifold what should I now do with this outlet? Do I plug it? (2) What does this outlet connect to from water inlet? If it's the "external bypass" that connects to the outlet housing, I assume there should
  13. Whew! Reinstalling the gas tank has been a lot of work!!! First off, I had the original fuel sending unit repaired by the good folks at Tristar Radiator (http://tristarrradiator.com). They do a lot of work on Datsun sending units and I highly advise that you check them out. However, I can't remember how to install the unit. If anyone can comment that would be greatly appreciated! Unfortunately I bought the wrong fuel tank straps -- purchased straps for a '75-76 280z which apparently differs from the later models. I just posted a separate question in the fu
