    3 Bolt Thermostat Housing Cover

    I don't think that's his picture, just an example.
  3. Sorry, I should have said two pins that go to +12V and 2 that are routed to ground, with switches or a component in each circuit. Those are their states when the relay is not triggered. I didn't communicate that very well, so that's my fault. Once the relay is triggered, then the output pin has 12V like you said. I'm glad you got it figured out.
  4. Four pin relays have two grounds and two positive, not 3 positive and 1 ground. I could guess at what the wires are based only on that, but you really should be able to figure it out based on the wiring diagram. Trace LY as far as you can and see if it runs to ground somewhere.

    Varying Intercooler Piping Size

    If you don't have a step you will completely stop all flow through the radiator other than the circular areas where the fans are. You need some amount of space behind the radiator for there to be airflow.

    Almost nothing outside engine parts will interchange between your two cars. You bought a 280zx, which is a completely different car than the 260z or 280z.

    brake cooling backing plate

    What kind of pads are you running? If you're overheating your stock pads, you may be able to just go to a more aggressive pad and avoid the work of setting up ducts.

    brake cooling backing plate

    Often times ducting is needed for road racing. The higher airflow prevents heat soak and fade that you don't run into with short Auto-X runs.

    DIY Hoop?

    That depends on what you want to do. A single hoop with two backstays? Include an X? Land on the floor or strut towers? The answers will vary quite a bit depending on what you're aiming for.

  12. Where did you get those door cards? I've been looking into a custom job and that's the exact layout and colors I had planned on.

    280Z A-pillar question

    Thanks! It looks like the slots are on slightly raised bosses. Is that right?

    280Z A-pillar question

    I'm interested in fitting a set of the plastic a-pillar and head rail trims that came on on the 280 in 1977-78. I can see that the a-pillar trims mount with just two screws, but I haven't been able to find a picture or see in-person how the mounting screws attach to the pillar. If there are simply holes in the metal, that's easily replicable on a 240z. If there are standoffs, that gets a bit more finicky. Does anyone know offhand or have a picture/car they could show me to answer the question?

    Drilled for cooling

    My only concern was that plumbing in all of the cylinders might reduce the flow gains out of 5 and 6.
