'75 280z 350sbc

Recommended Posts

I have an rx7 I'm rebuilding, formally an LS6 swapped car I may be going 2jz with. I know it would be a long time before I'll be driving my FD and wanted something to drive for now while I take my time building the rx7 so I starting looking into something else. After a few hours of searching I found a 1975 280z for sale on CL and moved forward into making a deal for it. It was described as perfect running and driving with only needing minor interior work and new brake pads. This will be picture heavy and a little bit may be out of order.

Went check it out, it had no major rust visible so that was a bonus. It ran and drove under its own power so I loaded it up and took it home.

Got it home and starting looking over everything more thoroughly.

Gave it a wash for the first time. Also removed those lights and spoiler.

Under the carpet most of the wiring was spliced, wire nutted, and taped together. After a little scraping on what looked like surface rust I found a few bad rust spots. The brake pads were fine, the calipers were seized. I ordered some new ones and replaced, maybe later I'll upgrade them and do a five lug swap. This car needed a lot more work than what was lead on to believe.

Moved the car under my carport to work on it out of the sun, need to strip the interior and some exterior to plan for POR-15 and Lizard Skin. For S&Gs i put an FD Seat in to get an idea of what it would look like.

Most of the interior has been removed. During the first few days i made a list and big order for replacement parts, most of it has arrived and stored until the car is ready for them.

After a few weeks of stripping the factory sound deadener, paint, and rust the interior was ready to be prepped for POR-15. I put an FD roll bar inside just for the fun of it, no plans on using it in this car.

I did order a roll bar made for the S30 but not sure if I'll use it or go with something else. Pulled the car out of the car port to give me some room to move about while applying the POR-15. I got new bumpers in so went ahead and removed the factory ones.

To make working in the sun bearable and to provide the cars with a little protection from the weather I ordered a canopy. With the wife's help I had it assembled and set into place within a few hours and was happy with the result. Will make working a lot easier during hot or rainy days, and I can reinforce it in the future to make it a more permanent set up.

There were a few small rust spots, I didn't see the need to cut a whole floor pan to weld in new pieces. I used fiberglass and resin for the repairs, it was only in 3 places. After the rust repair I used metal prep on the bare metal to get it ready for POR-15, this was my first time using it, I'm sure it won't be the last.

I applied two coats with a brush 6 hours apart. I think it came out good.

After giving the POR-15 a few days to dry I went right into masking and filling threads with tape before spraying the Lizard Skin, also my first time using Lizard Skin. I have another kit to use in my FD for later, I used Fat Mat originally for that car but will remove it for Lizard Skin.

I went with the sound deadener and ceramic coat kit, 2 coats of each. Pictures are between coats and cured of each. POR-15 and Lizard Skin are probably overkill.

Next thing to focus on is Wiring, being that the majority of the cars wiring was loose wires with wire nuts i removed everything and decided on a 21 Circuit E-Z Wiring Harness. The Harness using factory connectors but I didn't have much to go off of so order 3 prong and 2 prong connectors and some assorted grommets.

Got a new Air Dam in, still need to mount it. Decided on using Riv-Nuts to mount the 3 Piece Spoiler. Z battery tie down will be used, the battery was just sitting in place. Got some Z coasters just because.

The interior is mocked up temporarily so I get see where and how to route the wiring. I'm doing a lot for the first time on this car. The FD Seats fit good, almost a direct swap. I'm waiting on SpeedHut Gauges to come in to finish wiring up the dash.

The only thing keeping the car from driving is to finish the wiring and install the fuel tank, i took it off to clean it.

The ball valve might not last long with gasoline flowing through it instead of water.  Wire nuts are always bad.  Weird that somebody would remove fenders to put louvers in that spot.  Looks like a Baja rig, but with potential.  Can't tell if your pictures are before you got it or after.  Good luck.  Edit - not trying to be negative.  But you have a curiosity there.

Nice progress!  Looks like you're really making quick work of it.  Keep the updates, and pictures, coming!

Thank you, I hope to get far with it soon.

I don't know why a lot of things were done the way they were, I'll continue to correct what I can.

 

 

Been bouncing on and off between this and the rx7.

I did some moving around and cleaned it and the rx7 up a little. I also need a nice warm day to take the carpet and vinyl out to sit in the sun to fit right. The new interior went straight from the boxes to the install. Then I have the bumpers and front air dam to put on to complete the exterior. I'm thinking once its done I may list it to fund the rx7 once and for all, or at least trade it for a running one to be driving an FD again a little sooner, no telling.

I let the vinyl and rx7 carpet sit out in the sun to make them easier to work with. Haven't had a sunny day in weeks.

I was supposed to get the fuel hoses done, I ordered 5/8" and was sent 1/4" so I'm put off another week from finishing my fuel system. Still have plenty to do so next on the plan was to get the wiring done. This week I was able to get the rear section done. This is the first time I ever rewire a car and I think I'm doing pretty good from the condition the wiring was in before. I reused the old connectors with new terminals where I could instead of splicing new wires with old wires. It doesn't seem like a lot but it took a lot of time to research and plan what wires from the EZ harness goes into factory locations. Next week I'll have the front finished then may need help from a buddy to do the ignition and dash. 

I'm just saying, if I ever get rid of this car the next person will get a deal, the interior has been stripped, POR-15'd and Lizard Skin'd, new wiring and new interior ready to go in. And that's just a start.
