  1. Thanks, guys! I took both of your advice and contacted some local glass shops. I should be all set now. Unfortunately, I am clumsy and dropped one which broke, but shouldn't be a big deal. I am going to make a separate post in the future overgoing the rebuild for anyone else who may run into the same questions I had.
  2. Think they can replace the glass? I removed it from the housing by boiling the panel in water melting the glue. Thanks for the advice!
  3. Hey Guys! I have some sport mirrors for a 280z where the glass/lense is is pretty rough condition. Do you know if glass this bad around the edges is able to be cleaned up? If not do you know where to get replacement glass? I feel like buying original new sport mirrors is a little on the unnecessary side due to cost, and that I already have good bodies. The aftermarket plastic ones don't interest me that much either. Just trying to find a way to clean these guys up! Thanks in advance Here is a photo

  6. Thanks guys, I'll take a peek at those threads👍
  7. There you have it! Thanks Chuck for the kind words, didn't realize you were on this forum🙂 You all have been a great deal of help. Can't wait to rip the Z around town!
  8. Honestly, I don't know, I will have to ask. However, I think their final conclusion was that the injectors were undersized for the car.
  9. Time to settle this thread Forever! After about a year of tinkering with a very sick motor, and doing everything per the FSM manual to no luck, I gave up and sent my Z to a doctor to be fixed. The shop I took it to was Sakura Garage in Phoenix, Arizona and I highly recommend their work, as they are some of the most knowledgeable Z car enthusiasts I have ever met. Anyways, they decided something was up and hooked up the car with an AFR Gauge. With the car idling I think they said it was running somewhere along the lines of 24:1 being on the extreme lean side. So they turned my little potentiometer to control the fuel to full rich and could only bring it down to 20:1 (should be around 13-14:1 I believe). So they went through the entire EFI FSM and found absolutely nothing wrong with the car. They wondered if it was the injectors so they did full spray tests into graduated cylinders for fuel flow, consistency, and volume, and it looked totally fine. Swapped in a different ECU, still no luck! With fuel pressure solid, and literally every other option exhausted, they decided on a whim to just toss on a new set of injectors anyways and....... my motor purred like a kitten. Now they still don't know what exactly is wrong with the old injectors as they are what came with the car, OEM, and I had them rebuilt as one of the first things I did to the car when I bought the car. However, when I bought the car, (completely original) I remember the only thing disconnected were the fuel injectors. So my guess is that these injectors were the culprit to why the car was parked back in 1991. Anyways, glad its settled, figured I'd share this with the community in case anyone ever has a problem like I did. thanks @siteunseen, @Zed Head, @Captain Obvious, and anyone else for helping me a while back when I started this thread!
  10. Hey guys! Just a theoretical question here. I can't find really anything online about z owners who are running the 260s comp cam on their L28e or Z for the matter. So I figured I'd ask if anyone has, or knows anyone who has, used this cam on their Z. Does it make any noticeable difference in hp or torque? Is it able to be used with a stock 280z EFI system? Would you recommend it for someone trying to find just a slight bump in power? Really just trying to start a conversation of what your thoughts are about this cam. Here is a link to the cam I am talking about. https://zcardepot.com/products/performance-camshaft-comp-racing-cam-240z-260z-280z

  15. This intrigued me, as an issue I wasn't aware of, so I did some digging and came across this link. https://www.atlanticz.ca/zclub/techtips/plugs/index.html Inside the ink I found this: Historical Z Plugs so, I believe I am running the wrong plugs. Which is weird, because AutoZone recommended the NGK-BPR5EGP which is a hotter plug. Do you think it would be worth it to switch to the B6ES-11? I wonder if for some odd reason these plugs make the car unhappy. @dutchzcarguy thank you for the great catch. @AK260 Interesting, I will take a look at those resistance tests when I get home. The miss Is rhythmical at times in the sense that I can watch the RPM gauge bounce. However, when the gauge isn't bouncing and the engine is still missing, it seems random, as there are just distinct muffled gurgles out the exhaust with constant engine bucking. Regarding vacuum, it reads perfect, as I did all the tests and corrected issues in a previous forum post. Lots of new rubber everywhere.
  16. Haha, me two. First time I started it, I mixed it up and it wouldn't start. Went for the starting fluid😞 Sounded like a 12 gauge it backfired so bad🙂 Kinda cool, kinda terrifying. Equally stupid Anyways. For ignition I am running a Petronix Flamethrower 2 0.6ohm coil. I am running a stock distributor, but I just had it sent off to Advanced Distributors in Minnesota to be rebuilt and recurved. It looked pretty crummy inside, and I don't trust remanned units due to reports of inconsistencies. I am still using the factory ICM, ballast resistor, etc. I did clean the thermo sensor before I put the motor together. However, the engine doesn't seem to be affected with it connected or not, so I just leave it unconnected living in Arizona. All the bullet connectors are solid. I wired in the resistor for the WTS so I can adjust how rich the motor runs. No matter how rich she still likes to buck. All makes me think it is ignition. I also pulled apart the Ignition Control Module. It had oxidation and rust spots on the outside. The circuit board looks brand new inside, so I just let that be. Wish I could run it and see if moving the wires caused problems, or if it arced in the dark. Running out of things to look at, but those new wires going bad must mean something.
  17. Hey Guys, I battled a number fuel injection issues in a previous forum. With that system running right, I now have narrowed down the stumbling idle to something ignition related. The car takes a few seconds to start up, but when it roars to life it holds an idle. However, you can hear a clear miss, and the motor will buck around. I also want to note that I can free rev the car and it seems to smooth out at higher RPM. My first question is about the spark plug wires that I came across. These are/were brand new NGK wires from Zcardepot I installed last winter. The car has probably seen about 30 minutes of idling/revving in a garage since then, while battling injection issues. It seems as if the sealer around the wires has overheated and separated at the boot. What could this be caused by and why? Would this cause arcing around the engine? spark plugs don't look fouled. NGK-BPR5EGP I attached photos of 3 wires that seemed to have gone bad, and 1 photo of a wire that still seems to be in good shape.
  18. Hey guys long time no see, I was absorbed in a full suspension rebuild, so this thread got put on the backburner. Since I have last posted, I had zcarsource replace my pickup tube inside my gas tank. They did a great job, and it fixed the fuel flow/air bubbles problem. Now I can free rev the car easily up to 7k rpm and the car runs much better. However, I still have a problem with how smooth the motor runs. At idle it still bucks and jerks like it has a misfire and with the exhaust off the misfire is clearly audible. I can notice the engine bucking till about 3000 rpm, to where the motor seems to run smooth. Now as a last ditch effort to see if it was still fuel, I pinched the return line to see if it would smooth out. All that happened was the idle ran higher (with fuel leaks beginning to sprout), but still had the consistent stumble, so I doubt fuel pressure is an issue. I also want to note that I tested the fuel injection control unit, and all of the FSM tests checked out great. This makes me think it must be spark. However, I have a new distributor cap, spark plugs, coil, spark plug wires, and rotor. So the issue must be more complicated. I was thinking that it possibly could be the distributor? It has a small amount of side by side play, but I gap checked everything and it was almost perfect. So I am wondering if it is the transistor ignition unit on the passenger side kick panel. Does anyone know how to test this. I looked at it, and it looks pretty nasty. What are the signs of one that has gone bad? Tell me what ya'll think.

    The Strut Spacers are located between the Strut Mount Insulator and the Spring Seat in the rear of the car and are the counterpart to the front Upper Strut Bearings on 70-78 models I don't care if they are poly or rubber. I am in SOS mode and need to get these asap. Trying to move for college, but need to finish the rear suspension so I can tow the car. This part is holding me up. It is backordered everywhere I called. So if anyone has a spare set, please save me!

  21. I am going to agree that this is the issue because it was so hard to unclog, and I could have broken it when shoving wire and stuff through. Removing tank as we speak. I will send it off somewhere tommorow. Fingers crossed this ends the EFI nightmare for good. Never knew this was a problem until now, because the flow was much better before I drained the tank today, but still pulsed every once and a while. The difference is I have 8 gallons in the tank now, and I had a full tank before. Likely masked the problem until now.
  22. Ok I am going to keep stock cam. Didn't do injectors after all, because I think I found the real problem.... So the gas was old, sitting since December, so I swapped it for new gas and also replaced the filter I had running in the back. Put about 8 gallons in. The previous filter sure did do it's job. The first thing I ever did to the car was clean the tank with nuts, bolts, muriatic acid, and vinegar to shake all the rust out. I also cleaned out the pickup and return tubes with solvents which were clogged at the time. I then put a little filter between the fuel pump and the tank to make sure any pieces of rust or gunk I missed were caught Now here is where things get interesting. The car starts and idles beautifully without a miss when cold, or after sitting for about 30 minutes. Now I wondered what the hell was happening, and I knew it must be somehow fuel, even though the fuel pump bench tested wonderfully when I put it on the car. I went and looked at the little filter I replaced and here is what I saw. What the hell, is what I thought. I thought that the fuel pickup must be semi clogged, but that is not the case. When the car turns off it fills up instantly. That is when I noticed this when the car is off. This bubbles subside after about 20 to 30 minutes. When I start the car and watch this filter the stream is consistent and powerful to the filter. Then after running for a little bit the stream starts to spurt again with less power. Like there is air getting stuck in between. Have you ever seen this happen? Is somehow air leaking into the system? What is going on here, I am all eyes and ears. I am thinking there are rust holes in the pickup causing air to surge in or something like so.
  23. I think I am with you on this one. In the name of science though, my friend and I are going to rewire the injectors anyways tommorow morning. If something changes then miracles are possible. If not, then you can use my forum post as proof to debunk anyone in the future who thinks that their injector wiring is wrong.
  24. So you think that it is possible if the wires are connected backwards it can lead to issues? All six of mine are wired the exact reverse of this by accident. I tested by seeing which side of the connector was getting voltage when on the car, and the opposite side had voltage as apposed to this thread. No idea how I messed this up, as I thought I was careful. https://www.atlanticz.ca/zclub/techtips/injectors/connectors/index.html Regarding the cam, I will stick to stock, but I think I am going to use the internally oiled one. @Reptoid Overlords, ok interesting. maybe the header is just causing more noise to pass through. I might try one of those special tools to see exactly where the sound is coming from.
  25. Another update after a hard day's work. The Datsun has won again. Did a valve adjustment, some of the specs were crazy off. Mostly tight, but definitely not at what I set it to before. Redid the oiler gaskets with new proper ones. Realized that I didn't even have a gasket in the middle:( Anyways, fired it up, cold it was quieter, but once warm it was louder than hell from the valvetrain. I am thinking it's time for a new cam, internally oiled, and probably a hotter cam as well. So that's loss number 1 Number 2 I slapped on the potentiometer trick. Man that thing works like a charm to lean and richen the mixture. Quite a masterpiece, whoever came up with it. However, it did not fix the miss. The miss did go away when I had the potentiometer at about 3/4 rich. However, my eyes were watering from unburnt fuel, and it sounded like a vacuum out the back. With slightly more fuel I was able to get vacuum up to about 17 at idle, and it still ran fine. Still has a stumble though. Are you positive that fuel injectors can be wired backwards with no ill effects? With good fuel pressure, vacuum, electronics tests, I really don't know what the miss could be caused by. I checked to see if the EGR thing was rotted through by plugging the holes, but nothing changed when I did. I am starting to think it is spark related. Is there a spark control module? Is it somehow possible for this to cause a miss? On a positive note the suspension, brakes, wheel hubs, shocks is almost completely out and ready to be cleaned and rebuilt. Just stuck on the spindle pins for now.
