Are you going to ask these same questions to anyone else now?

Cats can stop up and restrict the exhaust

to be honest i havent even looked at the exhaust. Im assuming it does have cats. I did have a 10K potensiometer laying around and tested this hack from siteunseen and it did work when setting the ohms to ~1000. Car reved to 4500-5000 before shifting without any hesitations. im not planning on driving aggressive at all. but just trying to get the car running well.

This is the one I used with LED lights https://www.amazon.com/dp/B0811GTVH2?ref_=ppx_hzsearch_conn_dt_b_fed_asin_title_2&th=1

Its a long shot, but putting a feeler out for a 3.364 R200. Looks like only the '79 4 seater manual transmission s130s had them stateside.

Does it have Cats?

Thanks for that. We set the plug #1 position by TDC and the rotor position. So we ended up with that L20 positioning through our methodology by accident

As I was working on the car today, it occurred to me that perhaps the best KEY-ON signal I could hope for in the engine bay would be one coming from the alternator. After all,it will only have an output when the car is running. I have an internally-regulated 70 amp, 280ZX alternator so I won't be using the 1972 OEM voltage regulator. In fact, that location on the inner fender is where I'm clustering all the relays for headlights, electric cooling fan, etc. What do you folks proficient in S30 electrics think of this as a possibility?

Cody figured out the turn signals today. The signal flasher is a thermal variety even though it looks like an electronic flasher it's not. If we add just one incandescent bulb it flashes as it should. So I ordered some that are electronic with an additional ground. We'll see how they do. He also replaced all the bulbs in the dash gauges with LED's

@Mike It's still a bot!!

Are you sure your exhaust can breathe properly? Possibly the exhaust system could be a variable.

searching for a potentiometer is not so easy now adays. i miss radio shack.

I don't know if this is accurate, but for the L20, this site says the distributor orientation is different than what I would expect. https://www.gtsparkplugs.com/firing-order-datsun-l-series.html

Thank you for that info, ill see what i can get done. i would like to see if this would be a main cause and a fix verse a bandage. In the long run im doing to be redoing most of this with more modern technology so it might be a moot point.

So status, we figured out how to hot wire the car since we don't have an engine bay harness currently @SteveJ :) We have spark and we have fuel but we couldn't get it to fire. Even with Ether... We have good compression and we have the dizzy on the car on the compression stroke. Although the timing isn't set yet. But rotating it while cranking, we didn't get anything. No bump, no belch, no nothing... Valve adjustment was done recently My only idea at this point is that we flooded the engine with all the cranking time to sort the spark and distributors. Any other ideas??

You should never disassemble both sides at the same time! That way you have an assembled one to look at. If you didn't keep the parts well sorted then the auto adjust might not work. The sides are handed I believe

It might be the front, AFM? It'll spit and sputter and buck under load. A lot of folks have done this tweak. I did mine when there was a Radio Shack in every mall. Cost me $5 and it runs like a top.

Is it popping out the tailpipe? If so you should read this. I've got one on my '77. https://atlanticz.ca/zclub/techtips/tempsensorpot/index.html

I've been getting a 1977 280z up and running after ~20 years sitting. I've replaced all fuel lines, pump, tested for vacuum leaks, etc. I feel like ive tried to tune this thing with the AFM, TPS, and idle screw. If finally have it idling around 800-900 rpms and good power up to ~3000 - 3200 rpms then it feels like it loses engery and sounds like an airy fart. sorry but i dont know how to explain the feeling/sound. it doesnt sound like its about to die b/c its at higher RPM but it feels like it loses all get it up and go. it tried to increase RPM but does very slowly. this is very apparent on 1st and 2nd gear. When i shift into 3rd and 4th i am going fast enough im dont want to floor it. What should i be adjusting? ***side note*** when not in gear I can rev the engine 4-5000+ RPMs and it revs beautifully without hesistations. only when under load.

Do the half shafts in 1975 have replaceable ujoints or are they stakes like the driveshaft?

The good shops can find the specs or just take measurements. And there are aftermarket propeller shafts out there. Nissan calls the center longitudinal shaft propeller and the two "half-shafts" drive. You need to be aware of one big problem with 1975 though - Nissan used a unique flange bolt pattern on the differental. 76, 77, and 78 won't work on a 75. Motorsport Auto (TheZStore) knows, on their Replacement page. But not on their Performance page. Oops. https://www.thezstore.com/category/935/replacement-driveshafts Don't buy a Performance shaft from MSA. https://www.thezstore.com/category/827/performance-driveshafts

It looks about right. If you pull on the lever that the cable attaches to you'll see how it works. Each time you pull the parking brake lever that arm over the notched/toothed wheel moves over the teeth. As the brake shoes wear eventually the end of the arm catches one of the teeth and rotates the tightening mechanism, making it longer. When it's assembled correctly the end of the arm sits right on the teeth. An illustration of your picture is in the Brakes chapter.

I recently replaced my rear drum brake hardware but forgot to take a picture before disassembling everything. Can someone confirm if this is how the parking brake lever is supposed to be installed? I’m also not entirely sure how the lever functions in the mechanism. It looks like it might not be mounted correctly — should the lever sit on the right side of the cog wheel? When I place it there, it seems to keep slipping off toward the left side. Any clarification or reference photo would really help. This is the drivers side of the car

Hello, everyone. I am also a member of S30 World. I’m very happy to be a member of the team. Thank you Carl. Carl recommended me to Chris’s big project. In addition, I definitely thank Alan for promising to join the team because I am a member. Chris visited my house in 2018. I was very impressed that he was very sincere about all the variations of our car. And his dream was to establish and enrich the museum with cars that have received great restoration work. It’s all because of the Classic Zcar Club. We have been learning a lot from the people here. I’m making a lot of friends here. We are all connected in a simple way. Z. We know that there are no cars that have been restored 100% correctly. The S30 World is trying to restore the car close to 100% correct. Chris’s great passion is outstanding. Many enthusiasts have been involved in his project. It’s like magnets on the fridge. I think all the posts here are worth reading to make our beloved cars more beautiful. I think people who post here are like magnets too. As Florian said, we are simple. We want to enjoy the S30 more and spread the joy of our cars to the world. If you see the car at the S30 World Museum, you will surely like it. We need to correct the “100% correct” word into the appropriate word. But all the black painted floors and other little things are repaired in good faith, so even if we don’t fix it, you’ll like it. Oh, stay tune, I will report an interesting things regarding S30 World soon. Kats

Any of you guys have had a driveshaft made up. I need the name of a shop that does datsun driveshafts.
