1974.5 260Z ATLAS build

03-14-2026 ATLAS Z UPDATE: Since the intake was off, I went ahead and tackled the project I have been putting off.  Modifying the Atlas Industries alternator bracket setup to work on my project.  the mounting plate is 1/2" thick, and the alternator just wouldn't clear the frame rail, so after trying to cut the aluminum bracket down, I gave up and traced out the bracket on a piece of 1/4" thick steel and cut it out and drilled the holes out.  I then used my Dremel to counter sink the holes so I could use the bolts and everything that came with the kit.  I painted the steel bracket with silver engine block paint and the bottom bracket I had to trim 1/4" off of it.  Then I was able to install  he alternator (brand new AC Delco, nice unit), and then on to the fun part.....belt alignment.  Using a straight edge, I had to keep working little by little shaving aluminum off the provided spacer and then lightly grinding the back of the nylon pulley and it turned out great!  Then I went ahead and installed the fittings to use a 8AN line for the crankcase breather on the intake between cylinder runners 3 and 4, and I found that by leaving it black it is hidden and you cant see it, so that worked out better than I had planned.  once the intake was tightened all down, it was time to finish the intercooler piping.  The driver's side was VERY tight.  I used two 90 degree sections and trial and error and cutting them down I was able to come up with a decent arrangement.  so that piece, to be welded along with a frontal piece to weld a length on to eliminate some couplings were put together and I will take them to get them welded up then take all of the pipes to get powdercoated  with the "polished aluminum" finish.  I could get them polished.....but it would cost more......opinions?  Lastly I put together the intake side, switching to a 4 inch coupling setup with the GM factory style MAF meter.  it was 3.75 diameter, so I took some rubber strips that are adhesive on one side and ran a strip of it around the mating surface, and then I was able to tighten the hose perfect on it.  I did have to use the 4 inch to 3 inch reducer on the end, as the engine has pieces sticking out that won't allow for 4" pe, etc.  I have a 3" screen arriving soon which will be on the front and it should look pretty good.  I will have to get inventive to add polished/chromed to it to get rid of too much black.  maybe a very thin polished aluminum piece that wraps around it and can be fastened underneath?

 

Anyway, here are some pics: :)

03-16-2026 ATLAS Z UPDATE: My welder showed up today and welded up my cross bracing and a few spots on the trans tunnel where it touches the firewall. While here, he pushed on the outside of the windshield as I pulled the rope and got the windshield in. Tried to get the hatch window in, but it wasn't wanting to do it. So, I will have someone help me with that rear one later. I went ahead and installed my mesh cover for the turbo.....I had to go down a size to clear the engine. I got started on putting the door frames back in and getting the windows working right, more to do on that. PICS:

02-20-2026 ATLAS Z UPDATE: Today I got my intercooled pipes back from being welded up, and I decided to see how they would look painted. I used the Duplicolor silver engine block paint. I also was able to finally get the right length of hose for the lower radiator hookup. When time comes, I will tighten it up and assemble the intercooler piping! PICS.

03-21-2026 ATLAS Z UPDATE: After painting the intercooler piping silver yesterday, I didn't think it had enough "pop" to it, so today I I put a couple of coats of chrome spray over the top....I like it much better. I was able to get all the intercooling pipes installed. Then I went ahead and vacuumed out the car, and installed the carpets from Newark Auto I got on eBay. some carpeted pieces I am not installing, as I will leave the vinyl 260Z pieces that the car has from the factory. I dropped in my heel plates from Skillard and then mounted my dashboard and then set the console in to see what modifications would be necessary. The pics of the shift knob on the steel show that I am ready to hold it to the shifter, mark it and then cut out a shifter so that the shift knob is right where I want it. PICS! :D
