A to Z Posted April 7 Author Share Posted April 7 (edited) 04-06-2024 UPDATE: Well since I have dry rotten overflow hoses and a tank full of gas, I decided first off, to jump in the Z car and drive to Denver and back. It was a 117 mile trip, first one of any distance in the car, and it took some guts on my part to drive a 52 year old car so far from home (garage), especially something I had built. BUT....it went without a hitch.....my 280ZX Close Ratio 5 speed transmission ,81-83 variant with the "good" overdrive, and my 4:11 gears gave me 70 MPH at 2800 RPM....75 MPH at 3,000 RPM, and 80 MPH is at 3200 RPM. I dropped it to 4th and I was at 4300 RPM at 70, so the overdrive does make a difference. This car has verified 45K original miles, but the drivetrain is all new, as is most of the suspension and brakes. After getting home I grabbed the tool Duffy told me to get.....to adjust the brake master cylinder and booster. The tool is a god-send! I attached a video of it, but basically I used it, and a feeler gauge, set at .030 so to leave a bit of distance between the pins at adjustment, as I read somewhere its good to leave that much cushion. So, I got that adjusted and took her out again for a spin. Brakes are GREAT! When I stomp on the brakes the front wheels lock up and slide....never did that before.....my rear drums, even though I rebuilt them, just don't seem to work, and the E brake might as well be non-existant....so there is another project to figure out. I managed to get the fuel burned down below 1/2 tank.....here's to hoping that is low enough for replacing rubber fuel lines and filler neck. Took a few pics of the car as I always do....the closeups, if you can see the road dust...yeah I didn't wipe it down yet. When I took it out to test the brakes, I went through a local park and a handful of really tight turns with a 15 MHP limit got my attention, I went way too fast into them and threw the car into all of them.....I was trying to get it to either plow (understeer) or for the rear to break loose (oversteer), it wouldn't break loose, just stayed flat and did what was asked. I guess the near race car suspension works after all. The coilovers are set at the middle adjustment in the setting range. I normally don't drive like that on the street or in palces where people are, but I didn't see anyone and took a chance on the way up and back down. No one got hurt, and I found out what the car is capable of.....the car is better than I am capable of, so, I guess when you do all the suspension stuff, it really works. No more reckless driving on the street. Maybe someday she and I can go see how she likes autocross. Cheers! To view video, click "facebook" below and scroll through photos to the end.

A to Z Posted April 7 Author Share Posted April 7 (edited) As I have fixed little things here and there, small adjustments have had a BIG effect. a tad high idle....I corrected it, and the car came alive even more! As Boston George said....as it runs more and more and all of these changed parts "seat together" it will smooth out, he is right....it is becoming better and better. I now can say it is the car I wanted it to be 3 years ago when I started.....well 2 months shy of 3 years. The stroker is SO strong in the mid range, real street RPM's.....and the brakes are now ON, and the suspension is ON. Really nice to see it come together. Only thing left really is a cleanup on both door sills, rear drums and e brake, and fuel tank fix. It gets quite a bit of attention!

A to Z Posted April 7 Author Share Posted April 7 And now I wonder......how does a guy get to a point where he is bored with his Z car and wants to sell it? Quote Link to comment Share on other sites More sharing options...
A to Z Posted April 14 Author Share Posted April 14 (edited) 04-13-2024 UPDATE: So ordered the parts I needed to redo the hoses on the gas tank as well as a new filler neck, and decided to just get it over with and do it today. Very straight forward, but yes it is messy, and when I was letting the fuel drain, I walked away for a bit and came back to my 5 gal bucket overflowing! I blocked off the small port above the lines that feed and return from the carbs, and the driver's side port with copper plumbing caps....3/8 and 1/4. They did NOT fit right on, I had to use the dremel and open them up and then hammer them on. I then used the JB Weld to totally encapsulate them so I will NEVER have to do this again! I removed the carbon canister EPA "bag" and then removed all the hoses attached to it. I referred myself to the Z car Page that explained how to do that and used that as a guide (https://l.facebook.com/l.php?u=https%3A%2F%2Fzhome.com%2FRacing%2FFuelTankVaporLineMod%2FFuelTankVaporMod.htm%3Ffbclid%3DIwAR1CRB-K9MEA7BV-iDKRUhF4DIav92s3URvoLfdtm9JEXMoIZa1B12t_VUQ_aem_AYERpFuuWLmDxBWQcg6kDWB5XCyqV31fHhOPXT6lckUUhZyFHzoDsib2tLU11S3eWpEyR8tA5bH2sI_tP6vtGH7N&h=AT1WDx-JsAgk_WyvqIG7dCggOKAEPMcOvU_rP9QO-rEmKJK2ttY50DvJ6-PCI_GWdrjapjaidJhw8LLWxfHl0wpTPLTBeSv8v9P16mBjFCk_W4FHKLVVYJ9ZWtcunQHfdAsA&__tn__=-UK-R&c[0]=AT3tY1wiGHPTWcClhUVohf1JdT9khcNxdIdrsxpRoIL3t22WbWZubTvra0juI7yEygG6OuLpD2kD9_E58MH_ZoetYU0UwBJvIya4nNlS8FwJWwdzxBT8iXdGx4suCF0u1kPcBtxCaurzIpo_D2feerY8kllMHgmoV9WhYbKD6GQMLnrAhny1OPM_UQ24ffyXHQZUxL-GAzQkhUn1euANohA ). I got everything hooked up as instructed and closed it all up. I then poured the gas back in and no problems. Started the Z and let it run for a bit, and again, no leaks. It will now sit and let the fittings, or rather the BJ weld on the fittings dry up. After this, I decided to fix my seating situation in the car once and for all. I have thought of all the different things I could do to give me more room, and finally decided to cut out the lower cross bar on the rollbar. It is for looks anyway, and although I didn't want to do it, I decided that it IS my car after all, and I mod everything anyway, so I modded the rollbar. Cut and vacuumed it up and now the seat position is GREAT, but I need some foam on the rollbar angled bar as my head is against it. I have provided some pics and 2 video's at the end of the pictures.

A to Z Posted April 17 Author Share Posted April 17 (edited) 04-16-2024 UPDATE: Took the day and started with getting the Water Temp gauge working.......great feeling, had to dig back though the wiring to find the right wire and test it....really glad it's fixed.....I am noticing since I fixed my gas tank, that it is reading full when I poured 1/2 tank back in it.....and when I turn it off, the gauge doesn't fall completely back to E. I hope it will striaghten itself out once I get it out driving it around and fill it up for another leak test. I repalced the in tank sensor and it was worrking great....hmmmm. I ordered a repalcement clock from Ron at ZClocks. Upgraded to the Quartz and I am having him remove the green light filter, as I am using white LED bulbs. I also received the tires for my new 17" rims that are coming. I went with the Riken Raptor tires 225/245 45ZR17 size. They were on sale at Tire Rack, and they are a ZR rated all season.....I only drive on nice sunny days, but they will work. Less than $100/tire! Free shipping too! I jumped on my rear drum brakes, adjusted them to where the tire spins 1/2 turn or a bit less.....so they're right on, and so far, parking brake looks to be good as well. STRONG pedal feel. I rebuilt them completely a while back, but never did the adjustment...no wonder they didn't work! Torqued the wheels back on and then I noticed all of a sudden a really loud clacking sound while idling. Turns out 2 valves worked loose! All better now. Added some of my Walmart oil.....this is really good oil! Also finally got my Rising Sun stickers, put them right where I want them. Here are some pics.

A to Z Posted April 25 Author Share Posted April 25 (edited) 04-24-2024 UPDATE: Ok, so I went out to tighten up the valves, get rid of the looseness and get things "right" in the engine. Mission accomplished! The crows foot wrenches I bought do not work with the torque wrench, there isn't enough room, so I decided to tighten them by the Armstrong, "oougha dooga" method. Engine started up and runs great, purrs like a kitten! I then decided to Leak Test my gas tank, 99% good, the seam on the tank stated leaking...I got some JB Weld Steel-Stick and put it on the seam to stop the leak. I may have to put just a bit more on there, but the majority of the leak is gone. Thank goodness! I added some roll bar foam to the rollbar where my head rests, and I also have the crucifix I bought on my deployment to Afghanistan back in 2009 hanging from the rear view mirror now also. I also got it out and drove it just a little bit, it's so nice to have it running better and better every day. The rear drums are working well, but the e brake has to be pulled up high to work, so it's either adjust the handle form underneath, or replace the cable as it is stretched. 2 Videos are available to watch if you desire.

A to Z Posted May 2 Author Share Posted May 2 05-01-2024 UPDATE. I recevied my "new" clock from Ron at Zclocks.com. I paid extra for a quartz movement instead of the old stuff, and I had him remove the green light filter, since my gauges are all lit with a white LED setup. Anyway, I installed it today and then covered the 2 spots on the rollbar with rollbar foam where I had removed a rear brace. I then took it for a short drive, and then went about more little this and that finishing things up. I pulled the door data plate off and the "big" job left is to restore the door jambs on both sides, so I have that to look forward to. Aside from the 17" wheels arriving and setting the suspension height for them, the car is basically done. As usual, I took a few extra pics, just to look at stuff from different angles. Cheers!

A to Z Posted yesterday at 06:13 PM Author Share Posted yesterday at 06:13 PM 05-11-2024 UPDATE: One of the last things on the punch list is to get the door jambs cleaned up, so I did that today. I also drained out the transmission oil as it is GLP-5 and is bad for brass syncros. I then refilled it with RedLine MT-90, which is of course synthetic, and is GL-4 rated....safe for brass internals. I also went ahead and undercoated the bottoms of my door sill plates. I will take them down to J&S Polishing to see if they can be polished, as you know they are very thin, we'll see! Pics: Quote Link to comment Share on other sites More sharing options...
