    Starting Carb Conversion: Flat Tops to Paltechs 1 2 3 4 13

    by Dadsun

    I bought this Z (1973 240z, white/red, build date 10/1972) in April from the original owner, and have been working on restoring. (Will post some interior pics soon, hopefully.) As some of you know, like @Captain Obvious and others, the original flat tops were neglected and this car has been driven about 5K at most, in the last 20+ years. So, after some input from the board, and looking around, I settled on the Paltech round top SU carbs. They are beautiful. In fact, I'll have to clean/polish/replace the rest of the engine compartment elements to keep them from looking crappy by comparison. I an not a mechanic, but consider myself handy. I need some help on w…

    Japanese characters on the glovebox liner 1 2

    by JDMjunkies.ch

    Hi there. Both me and my friend have a genuine swiss-market 240Z. As @HS30-H pointed out in the past, the three japanese katakana characters ス イ ス on the glove-box liner stand for "su-i-su" and mean these two cars where destined for the swiss market (suisse) What i'm wondering now are the Characaters next to the "swiss" tag: I have some kind of "F" or "P" in a circle left of the swiss mark My friend has a something like an "A" right of the swiss mark. Since it was written there for a certain purpose during assembly or after, i guess it has either to do something with the equipment variant (colours maybe?) or the destination too. But google…

    Acceptable Antenna Replacement

    by Tirnipgreen

    Hello...I have a 1973 240-Z that needs an antenna to fill the hole where the original one once was. I would love an original, but I am not willing to spend the kind of money that I see them for on Ebay, etc. Does anyone have a suggestion for a respectable alternative...? I really don't care if it works...it could even be completely manual. I just want it to look good and retract fully. Thanks for your help...Ryals in north GA.

    240Z Poster for car shows?

    by jayhawk

    Hi all. After seeing these views of my ‘73 240Z during Motorman7’s restoration of my ‘73 240Z, I decided to take a couple of years to show the car at Z events and some concours events before returning it to Daily Driver status and getting it dirty. 😄 We (Motorman7 and I) took it to 2019 ZCON Branson (2nd place to Zup in the stock category) and 2019 JCCS in Long Beach. After I brought it back home to N. California, I drove it to a Concours event outside Sacramento, where I was the only Japanese car there. There was a lot of interest in my Z from a lot of folks, but also a lot of ignorance about Datsuns from the bulk of the spectators. So I want to develop a poster ab…

    Tranny/Diff Ratio and RPM @ Speed 1 2 3

    by texasz

    I need some help here. I've put together a lot of information (below) on possible transmission/diff combinations I may put in my Z and need a little guidance as to what this all means. Here's what I think this is telling me...the wide ratio (77-79) is going to give me more off the line acceleration in 1st and 2nd with a long wait to $^!# to 3rd and poorer highway top end speed than the narrow ratio (81-83) tranny. That being said, the it gets messy when you start to look at different diffs in the mix. These are the sites I have used as references for all this research. http://www.zhome.com/ZCMnL/tech/GearRatios.html https://tires…

    Relapzed 1 2 3

    by Mark Maras

    It's truly amazing how tough addictions are to get rid of. Case in point, I've been patting myself on the back for the last couple of years in gradually getting past the Z voices in my head that urge me to look for Zs that need more work than my back can handle and parts that I have no place to store. I no longer check out CraigsList on a daily basis and 'had' settled into a peaceful retirement UNTIL today. Today, I'm driving down a street in SE Portland (note the secrecy) when I happen to glance over at an old chain-link fence almost totally overgrown with weeds and brush. First thing I notice through a small gap in the brush is the rear of a 63 Impala. As I'm rememberin…

    Inner Gear Shift Boot

    by Tirnipgreen

    Is there some kind of retainer ring (etc) that holds the inner rubber shifter boot in place...? I see nothing in the parts diagrams. I am guessing that the shifter end gets smeared with grease and then installed with the pin and nylon bushings with the "E" clip. Then the small rubber boot goes over that. But shouldn't there be something that holds it in place...? Help...!

    Z car value

    by Montana Z

    Hello folks, After 23 years of ownership I am considering parting with my Z car. However, I'm a little stumped on how to determine a price point. I know original cars can bring good money on BAT and know basket cases can be had relatively cheaply but mine is neither. It has some rust and some repairs that I'm not happy with, but I don't believe any are detrimental. I have the original engine but have it pulled due to low compression on one cylinder and there's a Datsun Spirit SRT stage 1 engine currently in the car. The car has an auto transmission, but I have a 4 speed as well as a cl…

    Odd cylinder liner factoid. I didn't know.

    by Zed Head

    Browsing the parts manual and came across these factory cylinder liners. Didn't realize they were a factory piece. And, even better, you can get them on Amazon. http://www.carpartsmanual.com/datsun/Z-1969-1978/engine-280z/cylinder-block/26 https://www.amazon.com/Nissan-11012-N4200-Liner-cylinder-11012N4200/dp/B01LX9V3ZK
