You need to go back. You forgot to get the the center valance panel. Seriously, it is getting hard to find good examples and that one, although not in clear view in the photo, looks in reasonably good nik. The horns look good. Grab the brake proportioning vavle and brake switch unit. They and both NLA and those maybe salvagable.

Your question: What is this thing and is it important? That is the EFI Main relay on the 78 model, (after Aug-77). Yes it is very important. It looks intact, but the contacts could need cleaning. If its not working properly that will be a source for the EFI not working for sure. The EFI fuel pump relay is rectangular in shape. See photo (Photo is not mine, but from another thread here under "1978 Z - Fuel pump control relay")

Hi Sarah, Sorry to hear you are selling the 280Z. I can understand your reasons, knowing a little bit about your partners situation and having gone/going though similar circumstances myself. Me being in Europe, Ill leave it up to other fellow members to advise you on pricing. Over here the prices are much higher because of transport and importing costs. One thing I want to say; who ever buys your car will be buying a car that has been looked after by a knowlegable Z enthusiast. I see that a little like buying a bisiness. Some businesses have little good will, some have a lot. Good luck selling. Chas

Guy, I would try a piece of 1" pipe or maybe 1-1/4" pipe, weld a socket on one end for a socket wrench and tack weld it to the glad nut. 1" should be small enough to give you room to tack weld it in a V weld fashion and still slide over the shock. 6 to 8 good tack welds should be enough and maybe a little heat to the strut. Good luck with it. Its a pita when something like that happens.

Thanks for reporting back. Nice to hear you got her going again. Have fun.

Mark, Is the lip completly rolled back. I mean touching the inner panel? The reason Im asking is it might be hard to coat and prevent rust form developing. It could also trap dirt and keep moisture a lot longer. I remember that from a friend who owned an old Holden LC Torana years ago. He rolled the lips and the cavity behind filled with dirt. That held the moisture and it rusted out in no time. Would be a pity if that would happen. You are still making good progress. That is good to see.

Hi, I forgot all about this thread and didn't post what I ended up doing. I did try to order some from Nissan with yhe old p/n, but they substituted something from the modern cars. Ebnded up throwing yhem in the garbage can. Then I tried the ones that SteveJ posted from Panduit. They work well and look similar to the originals, but are single use. They are designed for a hole around 6.5mm in diameter and the holes in the 280Z are 7.0mm. That means they fit ok, and maybe a little looser then yhe originals were when new. I purchased a pack of 100 for about €25. The price has increased a little since then. http://www.panduit.com/en/products-and-services/products/cable-and-wire-bundling/plastic-cable-ties/cable-ties-with-metal-barb/push-mount-ties/BP2S-D0 Hope that helps.

Are your four legged friends helping you with your built or just mental suport? Looks really neat all nice and shine with a fresh coat balck paint.

Rockauto sell a pick-up from the manufacture Standard. P/N: LX-507. I used that in mine.

It looks like the pick up has failed or you have another break in the wiring to the pick up. They don't cost much and you have already repaired a faulty soldering job on the wiring to this one. I would replace it with the Autozone unit.

Wierd coincidence, my 280Z has filler in exactly the same place. It's seems to be a skim coat and my "untrained" hands can't feel any damage or welding on the inside. Looking good btw. It will be a good solid car when you are finished.

I believe its the original 280Z distributor and TIU. Everything seems to point to it, like terminal block, no ballast resistor under coil and the E12-27 TIU. 280Z_1978_GM_HEI_Mod_Rev3.pdf TIU280Z1976_REV1.pdf

Since he showed us a photo of the E12-27 TIU, I thought it was a 280ZX engine in a 1978 280Z with the original distributor. The EFI harness doesn't include the ignition system, so that is quite feasible. The terminal block in front of the coil is still intact which would also indicate the 280Z distributor. The top view of the distributor doesn't give any view of the module. Based on the photo's posted above my conclusion was the engine has a 280Z distributor with E12-27 TIU and a 280ZX EFI system. I think The Wondous made a error quoting 260Z. It looks like a 280Z to me. Unless someone has done a lot of frame modifications for brackets like AFM mount.

I don't mind stolen ideas. Prevents a lot of R&D & redo work. I never get it right first time If you can fit the brace, I think I would do it. With the other braces you made, you should not need to brace the towers back to the centre of the firewall. That would help keep it clean. I can imagine dipping would be addictive. It really looks clean.

Looking good Chris. The bracing looks very neat and tidy. Did you get that idea from someone or your own inventiveness? Are you doing this because you can't use the tower brace over the bmw engine? Must be a pleasure to work on now all the metal is so clean.

Why do you want the change clocks. If you are doing it because you happen to have a ZX clock handy, it might be easier to try and repair the original. Do you still have the original? Here is a write-up by @monkeyman in australia. It seems an easy procedure to follow and would probably be a lot easier than converting a ZX. I think zclocks does an exchange service. How to fix your 260Z or 280Z clock - rev 1.pdf

I agree Zed. First identify the problem, then fix it. It could be a number of things causing his problem and changing stuuf will eventually solve it, but that can cost $$$$. It could be as simple as a loose pick-up coil and the gap is now too wide. Just saying.... The tests I listed in section 9 of the instruction are out of self evaluation and from the manual. It should be enough to identify where the problem is or eliminate sections until one item is left. Testing the TIU is very difficult for the home hobbyist, but using the process of elimination you can identify it ss the cause. A quick test would be: Disconnect the TIU plug and use a wire with spade terminal to make a connection to ground. Turn ignition on and tap the wire rappidly to ground while someone checks for spark using the timing light on the HT wire going from coil to the distributor cap. That would eliminate everything on the coil side of the system. Then it's down to testing the reluctor, reluctor wiring, TIU and power/ground to the TIU.

Judging by the photo in post#3 it's a E12-27 out of a 78 280Z or a ZX. Basically any manual from the 78 onwards should get you through it. The manual quickly moves over to specialized test equipment though. 1978_280Z_TIU.pdf 280Z_1978_GM_HEI_Mod_Rev2.pdf

The wire coming out of the left side of the capacitor in your first photo goes to a plug in the wiring loom. It's not connected to the coil as such, and it's not causing you this problem.

A photo of your situation would be nice. Take a lot of guess work out of it.

I agree Zed. You se it a lot with PU rubbers. The mustache bar rubbers are a good example. If you look at the originals, they have a certain amount of flex before contacting the "star like" rubbers on the top and bottom. The original could isolate much better. I might have a look at mine and try your idea on the extra spacers. One of the things I've regretted doing to mine.

Drivetrain noise is normal for the 280Z especially when you compare it with the 350Z. What can make it worse or more noticable is PU bushings in the mustache bar, PU bushings in the transmission crossmember and/or a solid diff mount. The type of oil your using can make the diff a little quieter or noisier. An RT diff bracket with the rubber stop touching the diff can transfer noise too. Back in the eighties a common complaint about the 280ZX was it lost a lot of the sports car feel when they introduced all the creature comforts like power steering, electric windows etc. The car was much "softer". My 280Z is heavy, but I axcept it. My wife doen't like driving it because the steering is so heavy

If you want to test the TIU, you can use the test section in an instruction I made for replacing the TIU with a HEI module. The test procedure will be the same for the TIU. The instruction is made for someone the has basic knowledge of the electrical system. Its basically a process of elimination since the TIU is a black box without special test equipment. Instruction - Fitting a 4-pin HEI module to 280Z 1977 RevD.pdf

I have never heard of them being interchangable. Seems strange that Z Car Source would say that without reseaching it better. Like Pop's Z said, I think the R200 mustache bar with the PU bushes is you best option.

I don't mind the urethane bushings in certain sections of the suspension. But then the 280Z is a little softer than the 240Z. I wouldn't recommend urethane on the tension rods, the mustache bar or transmission cross member. The tension rods can break due to the rigidity of poly urethane and it can increase bump steer. The mustache bar and transmision mount transfer a LOT of drive train noise with Poly urethane. I know this from first hand experience Steering rack bushing would be another to think about.
