Joe's 1972 240Z adventure


Recommended Posts

9-4-2022 UPDATE: I managed to finally get the car running ELECTRICALLY. I had to climb underneath and with a long screwdriver I removed the mixture set screws on the SU carbs that was keeping me from turning the mixture screws all the way in and then back out 2 turns. Normally it as a 4 position wheel. So, now I just have to turn the other needles in and back out to a baseline so it will idle without me having to pump the gas. I also had to replace the ignition switch again, and put a new coil in. 1972 means everything is old, and is suspceptible to being replaced I guess. Work continued.....I went ahead and tackled the area under the master cylinder......I sanded out the metal, then blew it off and masked off everything, then painted it white and then top coated it with Caliper clear paint which SHOULD be brake fluid resistant. I Lastly I scraped off some sticker residue on the inside of the windows and put the factory "OK" stickers on both quarter windows. Small steps. Pics follow.

9-6-2022 UPDATE: I got the Z to run, albeit it was smoking like an old coal powered steam locomotive! Out of the garage in a circle and back in. First time I have driven it, first time moved under it's own steam since it's been here. Have to take the small victories! So, I spent some time trying to figure out why it was just drinking fuel like crazy, disconnect the chokes, pulled the tops, verified the needles, N54, mixture nuts all the way in, yet still not only running, but blowing dark grey clouds everywhere, so I stepped back and started reading up.....and after shooting a text to Sal Ceja, he told me what it was....I had plugged off the vents on top of each float bowl.....without the air, the float just jams up and you get full rich......so that is the next step!

9-7-2022 UPDATE: Ok, so I got the carbs working well enough to sneak in a first drive. Down to the corner and back twice....stopped and put 10 gallons of 87 octane in. WIth the wide tires, the steering is tough! Also, now out of the garage I can see things I didn't see in the garage, so plenty to fiddle with. Now I will put the Gunson Tune on there and tune it, and get it ready for front end alignment, a vacuum brake fluid change ( my best efforts not good enough) , finish hooking up the lights, etc. and then I will have a driving project. Here is a video or 2 of it running and a walkaround, and 3 pics. I revved it so you could hear the pipe, but obviously the carbs are rich, but oh well, took about 15 months to get here this far, and I feel pretty good about it.....:)

9-9-2022 UPDATE.  I finally got my BRE sticker.....so, the last stickers for underhood are now on, the BRE sticker, and my Vintage Gulf Imola racing sticker....yeah, it's OLD.  Also had some time, so I tackled the big port on the back of the aircleaner that was all scratched up and looked awful.  I got a rubber plug and pushed and turned it in tight, then put a bead of superglue where it goes into the metal....then masked it off and painted it with 2 coats of satin black.  Then I took some wax, and polished out the backing plate.

9-11-2022 UPDATE.  Tuned the carbs, and got the backing plate back on.  Ran new lines for the float overflows I think it looks good.  Then I changed out my old turn signal and light switches/stalks for the rebuilt set I bought.  After getting the plastic covers back on, I went ahead and removed the grill, and began installation of my horns and the Headlight Relay Conversion MSA sells.  The bracket that was supposed to be with the horns wasn't there, so I made my own, and painted it satin black.  I managed to get the air pump installed right behind the horns inside the engine compartment, along with it's relay.  Next was the headlight relays.....I mounted the 2 relays on the right side inner fenderwell and ran the wires.  For some reason, only one headlight comes on....switch to high beam, then it comes on in low beam....so more to figure out.  Also turn signals don't come on or flash, no brake lights now, and now the fuel temp and oil gauges don't work....oh and the tach is spotty.  Stuff to do I guess.  I took a few pics and a video of the horn.....she is LOUD! :)

9/17/2022 UPDATE.  My air filter finally came in.  A previous owner had drilled a bunch of holes in the bottom of the factory air cleaner cover.  I remembered that 3M makes colored duct tape, and so I bought some and cut it nicely and covered the outside of the holes, then put it on the inside as well.  I want it sealed.  I then polished it up and took a few pics.  I may get reproduction stickers for it....pics!

9-18-2022 UPDATE. Today was an odd day in the garage. I managed to take the turn signal relay out, and I found it is a 2 piece arrangement one plugged into another. So, I put the new one in and absolutely nothing still. I went over to the passenger side and looked on the outer footwell.....apparently there is supposed to be a round relay there....I sure don't see it. I have a relay there that is rectangular shaped with rounded corners......at that point, I decided heck with it and started working on other items for now. I cleaned up the door jambs. On the driver's (left) side, I went ahead and cleaned it up, masked it off and decided just to repaint it, as my wet sanding just wasn't getting back down to thenice paintjob that was there before I did the bodywork and painting. I ended up with a few runs that I can address later, but I got it painted....I also went ahead and attached a couple of weatherstripping pieces, and then took some steel wool and removed what was left of the chrome "plating" on the plastic strip of the door panels. I then masked it off and used the Molotov paint pen I had to make it look new. Well, it didn't. The paint pen doesn't allow it to go on smooth, and looks choppy when done, so I took a rag and Denatured alcohol and wiped it off. I think I will spray it with the Interior SEM Napa red paint and just make it a part of the whole door panel/card. I cleaned it all up and got it ready for that, then went over to the right side and did the same, but also went ahead and installed the weatherstripping for that side that needed to be replaced. Thankfully, that side didnt't need to be painted like the Left/Driver's side. I also finished the painting of my grill to a dark grey. I put everything away and deicded to take her for a drive.....Well it ran great sitting still but driving under load she was very lean, lurching and popping. So I turned the mixture screws on the SU's all the way in then back out 2.5 turns. Now it ran great! I found a stretch of raod where I could then carefully step by step lean it out until it ran bad, then back up one spot. So overall I am 2 turns out PLUS "one click rich" or 2 1/4 turns out. Put the airbox back on and hit the road! For some reason the kickdown from drive didn't want to work, and I found that manually shifting the auto was better anyway. Manually shifting gives you a very quick shift....so not quite sure why shift kits are even sold......I CAN however see where the loose torque converter I have could be nice from a dead stop....she is a tad sleepy for a second or two, then takes off fine. I have an appointment in a couple days for front end alignment and a vacuum brake bleeding, as my best efforts with the speed bleeders still isn't cutting it. The tires are also self clearancing the flares as needed on bumps, etc.😃 Not damaging the tire at all, just shaving the inside edge of the plastic flare. I was able to reach under there and pull the filings off! 🙂 I am really going to have to get serious about my lighting and couple gauges that aren't working now. Everything else is fine. Exhaust really growls on a downhill at speed when I downshift and let the compression slow her down! Here are a few pics. 🙂

I super glued a small piece of rubber, a little square on each interior side door latch. So when you open the door and get go of the latch it doesn't hit the metal and rattle. 🙂

 

I can't believe how fast it shifts when I shift it manually.

Nice update Joe..  I like how you're taking your time and doing it right. Sounds like you have the SU carbs tuned pretty well.. and Cool how the exhaust has a good note and growl to it.  Seems like there are always little things to do. Keep up the great job you're doing.. Thanks...

9-25-2022 UPDATE. I managed to get a few things done today. I swapped out my hazard switch, pulled the center dash vent panel and stereo out, pulled the center console out and did some wire cleanup and more work on tracing wiring to get things working. I found a connector that was undone.....that probably had a lot to do with my issues. Funny thing is, if I unplug it, car starts fine, if I plug it in, car starts in the "on" position and runs with the starter engaged. I disconnected it, car runs fine, so I will have to figure out what is causing my car to run in the ON position from where I plugged it in downstream. Most of the lights working and the gauges......since the gas gauge didn't work, I checked out the wiring at the gas tank, and those connections were bad, so I cleaned them up did a little repair, and now it works too! While I was under there, I went ahead and rust converted the tank straps and painted the tank. I finished up the front end alignment, just eye balled it now it has just a hair of toe in. Today I also jacked the car up in the rear and adjusted my emergency brake....I did 3 small videos of that I will attach. After all of this work my blinkers STILL don't work......new turn signal relay, new hazard switch...hmmm . One headlight I have to figure out, and when the lights are on, one backup light is on....so just have to trace it out. I am setting the car up as a "a vent fan delete" and "radio delete".....with jacks to plug in a stereo if needed. The stereo I had in there doesn't work......I will have to test it to find out why. So, alot of little stuff today. here are some pics and 3 videos at the end.
