Turn switch relay mod

Hi all, I added relays to the turn switch to take the current load off the switch by copying the idea on the website below. The mod is reversible and by doing so will leave only hidden soldered wires inside the clamshell as the only evidence it was done unless holes were drilled to mount the relays. With this setup the heavy current still flows through the fusebox but only a small current flows through the turn switch itself. I followed this website posting but I used a different brand of

Heater blower motor squeal stop

It is possible to lubricate both blower motor bearings without taking the motor out of the car to stop squeals or other noises related to motor bearings. I realized this after I had taken the motor out to lubricate the bearings. Many have opted to replace the existing blower motor and fan with a Honda civic heater fan. I like to fix things so I oiled the old motor because it was turning slowly and was squealing. Oiling both bearings with the fan in place in the car can be done by taki

Firewall insulation pattern for 1/1972 240Z

Here are pictures of the firewall insulation of a 1/1972 240Z on a "fabric board" with lines 1 inch apart going both ways to allow duplication if for some reason someone wanted to. Note that the top edge of all three pieces of the insulation are lined up with a blue line on the fabric board. Pictures were taken in full sun and have shadows. To clarify where the black insulation poster board ends and the shadow begins white dashed lines have been drawn. This could be printed out and the blue

Throttle jerk fix

Hi all, This mod eliminates MOST of the throttle jerk but not ALL of it. I owned the car for 4 years before I noticed it still has a small amount of throttle jerk. The previous owner of my 240Z reduced throttle jerk from idle to take off by bending the upper arm of the "turnstyle" as seen in the attached pictures to a stair step shape effectively shortening it. This mod is no cost, possibly reversible and requires no welding, drilling or adding parts. The connecting rod with a nylon bal

San Diego 5th ave Auto Showcase Oct 13 2013 Japanese class?

Is anyone planning to go to the 5th ave auto showcase in San Diego Oct 13? I spoke with an organizer Brandy and asked her if there is a Japanese class, or way to group some vintage Japanese cars. She told me that there are discounts available for any club or group if 18 cars minimum can be organized. They would reserve a part of the block just for up to 25 cars. Admittedly, I do not have Datsun Z etc. I have a 1967 Toyota Sports 800 here in the San Diego area. I would like to see a group like

1971 240z L24 engine with triple dcoe 40 webers leaking coolant

I have a 1971 240z that I have been restoring eight years the end of next month 8/13. I had a machine shop rebuild my engine which took the guy two plus years to do. I finally got it in the car and went with thriple Dcoe 40 triple carbs and the engine runs fine. I noticed a month or so after the engine was in the car that there was a small amount of coolant on the block where there are tabs on the block that stick out past the head. I pressurized the cooling system and dropped pressure so I pull

1977 280z rpm tach gets stuck

Hello I have a 1977 280z and the RPM needle gets stuck from time to time. when I park the car and leave it off over night it will reset back to zero. This is my first post so I don't know if I am explaining myself correctly. I am looking for some guidance of what steps I should take first to check it without having to dismantle the dash. I know there has to be someone else that may have or had this problem. Thank you and I hope I am posting this correctly. Open to some feed back.

Please HELP! Wiring Diagram for 1983 280zx GL

Hey Y'all! This is my first post. Please forgive me if this has been asked and asked. I have been searching for the wiring diagram for the OEM radio in my '83 zx. I can find the one for the non-GL, but no luck finding the one for my car. I am replacing the 30 year old worn out unit with a new aftermarket system. I plan to cut the old harness and reconnect. Any help would be much appreciated! Thanks, BB

Cowl leaf screen

This mod is reversible leaving no trace. Using silicone rubber sealant I glued a piece of aluminum window screen I spray painted black onto the bottom of the cowl where the holes are to keep leaves and other debris out. The screen helps prevent corrosion from debris trapping moisture in the area where the windshield wiper motor is. Mike Looking at bottom of cowl, screen being glued on:

Working on suspension

I want to coilover my car, but scare to chop off original struts. So, I've looking for spare parts. Luckily, local Pick N' Pull has new inventory of same year of my Z. Before pick them up, I study how easy to remove suspension struts from the car. I learned removing spindle pins from strut is one of the hardest job... Friend suggest to get yellow tank of propane to heat up and hammering one the spindle to move back and force to loosen up before using spindle removable tool. My spind

Making an inspection light lens

The inspection light is is NLA or very hard to find at the least, so I decided to try and make the lens. I had a light in good condition, but the lens was brittle and badly faded. Since I had all the equipment for making a set of tail light lenses for my 280Z it was not too much work to try make the inspection light lens. The Equipment I used: 1. Vacuum chamber and vacuum pump. This is needed to remove air from the silicone resin used for the mould and the clear resin used to make the lens. You

Hood emergency release (plus handle mount stripped threads fix)

Hi all, This has been done before by others, the following is my experience. I added a second hood release cable so now I have two of them in case the original cable breaks. Getting the hood open after the cable breaks is not particularly easy in my view of how others have done this. The easiest way to do this IMO is to do what someone else did, loop a steel wire through where the original hood release cable attaches to the latch under the hood, run it through the firewall grommet for the

Removing heavy bumper

Wanted to get reproduction Japanese Fairlady Z Gille Mesh, I remove front bumper to see the capability. Also plan to mount 240z bumper. After removing bumper, the front height is raised a lot. It's more complicated to remove valence compare with 240z. 280z got extra metal plate for bumper mounting position that prevent direct mount for 240z bumper. I thought Datsun Spirits blog used to have photo of the metal plate removal, but he deleted blog post. So don't know how much metal I should r

I would love to have an LS1, but quite frankly, i think it would be too

What do you do after 10 years hybernation?

After 10 years hibernation, I started basic staff. My goal is to run engine at first. Engine oil & filter change (5 qt for $15.99) Antifreeze coolant change (10 qt for $14) I bought cheapest oil since this is just testing purpose. I learned that Pepboy mobile coupon is really handy and beat the price from any other auto parts shop. off course, gasoline change. Drain 10 years old gas... It looks like... pee After replace fluid, start working on electric items. Change Battery ($100

It was running when I parked... 10 years ago.... Often heard from seller

I just got '75 280z. The car was parked on the car port for 10 years under the sun shine of CA weather. When I checked the car, the body is fairly good condition, only small ding on passenger's side door and fender. Rust is on the hatch area, but not cancer rust. Finally the car got towed to my home. The fun began

Im Stuck between a rock and a hard place!!!!!

I decide to drive my 280z over 220 something miles(Panama city to Jacksonville FL). I wrongly assumed my car had oil and was ready to go. After 2 hours on the road, I noticed as i drove up steep roads my speed would go down. Then i notice i couldn't get past 70 going down. Then i was below the minimum speed limit which was 50. Lucky for me it was 9 or 10 at night. Then my car started to shutter. I pulled over and checked the fuel pump...... No leaks. The engine looks good. My first thought was o
