In my experience, I wouldn't say that carbs are easier to maintain than EFI. I have spent many years reading, lots of trial and error, but I've reached the point where I feel I can handle any problem that could develop in the EFI system. As far as carbs, I don't have extensive experience but some. Believe it or not, I probably know more about flat tops than round tops. I had flat tops on my 510 and with the help of a long time friend and Z mechanic, became fairly proficient at tuning them. That's why I feel that they are no worse than the round tops. That's a rather unpopular viewpoint here so I won't elaborate on that topic! As far as carbs vs. EFI, I guess it really comes down to what you want to do with the car. If I was to build the 'ultimate L6' it would probably have triple Mikunis or Webers. But the turbo guys would most likely debate that.

I wonder if it would be worth anything to the 510/Bluebird crowd?

Well, I just looked at the microfiche and a Z pump is different. Oh, well, I tried!

d***, I have a mechanical fuel pump if you're interested. It's brand new in that it's never been installed on a car but I've had it laying around amongst my parts for so long I don't even remember where I got it from. It was made by Kyosan Denki Co., Ltd. It's in the box still wrapped in plastic and has three gaskets and a little info sheet printed in Japaneese and English. It is, however for a four cyl. The box says 'NISSAN BLUE BIRD 510 BLUE BIRD NEW" and it's part number is NP-456. Is there a difference between the 4 cyl and the 6 cyl fuel pump? If this is something you can use let me know.

Alfadog, I said that my rant was 'tongue-in-cheek' including the 'American bashing' comment. I didn't take it as snide. I was merely implying that by discussing whether or not this whole thread was 'off topic' we were getting more and more off topic. All I wanted to do was view more museum pictures.

Not controversy really, just opinion. Let's talk cars instead of getting even more 'off topic' by wondering if it's 'off topic.' Look at how much time has already been spent on that. It's nice to know who designed them but it's really of no use now except for the historical aspect which has been discussed to death.

I wasn't referring to Goertz. That was just part of my rant (tongue-in-cheek) and it was in response to Alfadog's comment My only point was that I can enjoy these cars and reading about them without worrying about whether or not it's an on topic subject or who they were designed by.

HERE WE GO! (again) Besides, Alan has already said it. But I gues it wouln't be CZCC if we didn't open up topics that have already been discussed to death and discuss them again. So where are we now in this Toyota thread? Off topic? In which direction? The Goertz myth? American bashing? I would really just rather look at pictures of the cars. I'm done!

Whatever! If this site can't even seem to agree that Skylines, 810s, ZXs, etc. are on topic then why worry about a Toyota. Just post it. No need to spend time discussing whether or not it's on topic. Especially when the logic is based on material that is questionable at best.

Sounds like you need to go through the cold start system. Thermotime Switch, Cold Start Valve, Air Regulator. Also check the temperature sensor. Sometimes, it's just a case of bad connections. If the cold start valve operates (bad thermotime switch) or leaks (bad cold start valve) after the car starts, that would account for the richness and difficulty accelerating. Do you have a Factory Service Manual?

As Tommohawk said go to http://zhome.com and look for their 'index of technical articles.' In there you should find a couple of good write-ups on tuning S.U. carbs.

Click on 'User CP' and then 'edit profile.' Scroll down to 'additional information' and you can add your location from there.

Well, I said freeze plug because in the pictures it appeared to be coming from inside the mounting plate. If it was coming from the other mentioned sources wouldn't you be able to see evidence of coolant leaking on the mounting plate instead of just at the bottom?

Freeze plugs on the rear of the engine? That wouldn't be good news since the tranny would have to come out to replace them.

As they have told me on a few occasions :classic:

Yeah but everytime I've seen something like that in a junkyard they wanted some stupid amount of money for it.

Being a 75, it has a voltmeter. What reading do you get when it's running? Should be above 12 approaching 14 when it's running which would indicate that the charging system is working properly. Should stay around 12 volts when the car is turned off. If not, the battey is either not fully charged or bad. Check these things after charging the battery.

Not being a scotch drinker (or any other alcoholic beverage for that matter) I'm unfamiliar with the term 'single malt.' But when my father was alive, his favorite scotch was Chivas Regal.

Dave, I've always loved the look of your car. Your add-ons and upgrades seem to go together very well. Looks to be painted the 350Z Blue. How come you've got Cali plates in Texas?

I let out just enough water to drop the level below the water neck. Check your Thermotime switch. It should only show continuity when cold. It's easy to check. Just cut of a connector with a couple of inches of wire from a junkyard car. Connect a volt meter to the Thermotime switch (on the car) and check for continuity.

No, but I've tried working in the bay of an Infiniti J30 and it can't be any worse! Give me an S30 any day.
