Are you missing these spark plug wire looms / stays that I boxed in green? If so, it's time to start hunting for some, they are normally included with the car.

My RPM's pretty much stay steady idling at the lights. Don't know if they do ethanol blended gas in Panama? I do have ethanol free fuel where I live and I run it in my Z. The gas is more stable without ethanol and the car is much easier to start when cold (you probably don't have cold in Panama).

Jalex, I was out cruising today in about 90 degree F temp in stop and go traffic. When I looked at my temp gauge it made me think of you. I run a 3 row Champion radiator with electric fans 160 degree thermostat, also converted to Evans waterless coolant back in 2017 as it has a much higher boiling point which keeps steam bubbles from forming on the cylinder walls. Also run a ZX electronic distributor and coil with Taylor plug wires and coil wire, resistor deleted. ZTherapy did my SU's back in 2017 and I've never touched them since I put them on the car. Car runs just fine in heavy traffic with my temp gauge looking like this. This is about as high as it ever gets, but it's never been an issue with the way the car runs. Engine is original, never been out of the car.

Jalex, With your car we never know what might happen next. 😎

Should be just fine.

I've done LED on all external lights. One thing I found is that LED bulb color should match the color of the lens it's going behind. This will give you maximum brightness. The other thing about going all LED is the reduced stress on your harness as this substantially reduces power draw.

Myself, I was 34 When I got me first CD player for Christmas 1984 and the first 2 CD's included were DSOTM and Flim & the BB's - Tricycle. By that time I had collected over 1,000 pieces of vinyl and yes, it's taken care of, always jacketed, cleaned on every play, decent turntable and cartridge. Once I heard these CD's I never looked back! I now have over 1,800 CD's that are now ripped on my LMS server. I'd guess somewhere between 1/3 and 1/2 of my vinyl collection has been replaced on CD. I'm no audiofool but to me CD was a very noticeable improvement over vinyl. There were other conveniences with CD... Just play the end of the track "Runnin' Down A Dream" on Tom Petty's "Fool Moon Fever" CD.

Yes, the person that "invented" the headlight wiring upgrade and the "Alternator upgrade Kit" (I'd also recommend this) for 70 through 72 240Z's is Dave Irwin. MSA has pretty much taken over the continuation of Dave's most excellent wiring mods.

The MSA harness is plug n play. See my post immediately ahead of yours. Also, if you plan on LED headlights you will want the MSA harness as it changes the power / ground arrangement on the headlight bulb connection. See this post for a description of what I mean. 240Z LED Headlight Wiring - Electrical - Classic Zcar Community

Can't answer your specific question, but I would highly recommend the MSA Headlight Relay Upgrade Harness, 70-73 240Z . This is a plug and play item and totally reversable. It puts the headlight draw directly on the battery and removes from the steering stock and fuse box.

This will sound stupid... My clutch issue was the slave had failed like a blown seal so pressing the pedal just pushed brake fluid out of the slave and the pedal just went to the floor. Since the new master and slave (I had the external spring slave to begin with) were the same as what I took out, I just measured the distance on each shaft of the old and then set the new shafts to the same length rather than following your diagram. This did the job and has been good since 2017.

At the point where you leave the .08 inches the spring is fully relaxed. It will stretch and have tension when the clutch pedal is pressed in.

I did both the slave and the master back in 2017. Used these from MSA and they're working just fine. From reading there's a recommendation that you should probably replace both at the same time.

The only other place I can think of that will turn on the brake light in the speedo is the brake warning switch.

My car is pretty close to yours SN wise, 17486. It has the E31 head and 4 screw carbs.

I went with the 6 to 1 ceramic coated headers and ran 2.5 inch exhaust the resto of the way out. I think this helped a bunch to channel heat away from the intake manifold! Used a Magnaflow 10426 in the tunnel for a resonator and a Magnaflow 13216 for the final muffler. Had an exhaust shop build the exhaust from the headers out with a chrome angled tip at the end. See attached pictures for the exhaust from the headers out.

The big reason I go for the Trico 43-180 is frame around the rubber is metal rather than plastic. If your blade holder for the wiper blade is the stock one for a 280Z the 18 inch blade will fit just fine. There is no 43-170 blade, only the plastic rubber frame 44-170.

Sorry, can't answer the question as I don't have 17 inch frames. My frames are just under 18 inches and I would use these blade inserts.

The mechanical fuel pump appears to be after market. It's your choice whether to stick with mechanical or electric fuel pump. On my 12/70 car I converted to electric fuel pump back in 2017 and am happy with that decision. Seems like there have been recent problems with some of the after market mechanical pumps. If it's originality you're after they were mechanical. There is the fact that even though they were mechanical, the stock wiring harness was installed to support the electric pump at the tank that made the conversion easy for me.

Great find, wish this had been available 9 years ago!

@Warty I followed this guy's guide to the hoses when I refurbed my tank back in 2017. The hoses were all the exterior braid so they look stock.

Back when I did mine I ended up using the original hose for this one as mine was in decent shape and this particular hose seemed to be unobtanium at that time.

Looks like the tank has been sealed with a gas tank sealer. Did a quick search and the "PPG 833K086 Yellow Fuel Tank Coating 1.5 gal Kit" is a likely candidate for your yellow tank interior. From your pics it looks pretty clean!

@TomoHawk I've been under the impression that 70 through 78 Z cars all use a 18 inch blade. These replacement blades are known to fit the 18 inch frames.
