Japan Quake
Coop, You mean Narita airport is operational again? That is good news. I have a co-worker who sent us an email from Narita after the quake. He was waiting on his flight and they shut everything down. I haven't been able to get back in touch with him since. Hopefully he is on his way to the U.S. Stay away from the seafood in China, and have a safe trip home.

Not Z related but the Skyline guys...
I found a snippet that refers to the underlying issue here: http://www.leftlanenews.com/r32-r34-nissan-skyline-imports-halted.html My understanding is that for cars that are less than some age, (and I do not know what that age is) the NHSTA requires that the car meet all the safety standards that were in effect in the year of manufacture before the car can be sold in the U.S. One of the safety standards in place in the 1990's requires crash test data to verify compliance. Apparently a company named Motorex paid to have crash tests performed on the R33 model of Skyline, and after it passed they claimed that the results also applied to the R32 and R34 models as well. Eventually the feds discovered that there are significant differences in the unibody strength of the different models and clamped down. By then there were a lot of the untested vehicles on the road, and the people who ended up paying the price are the ones who own the car at the time it is tracked down. However, if someone was willing to pay for and sacrifice several cars for the testing then if the sample cars passed the test, the remaining examples would get a reprieve. If this is protectionism, it must not work very well; considering the market share that "foreign" car makers have in the U.S.

Hood Closing Alignment
That is how my hood works, I have to "release" the safety catch to get it past that point when closing the hood. I wasn't able to adjust this out, but I didn't try very hard because it seemed like it was better to have a reliable safety catch than to have the hood close easily. That was a choice that I made. I suspect that you could enlarge the mounting holes for the safety catch and move it rearward slightly to make it skip past this point when closing the hood.

280z 2 core, or 240z 3 core radiator?
If you intend to buy a new radiator, get the 3 core. The difference in weight is negligible, and the difference in cooling is significant.

Got Bike?
I ride a touring bicycle in the summer. It is a Motobecane Grand Jubilee. I've will have owned it for 31 years next month. (Which is about equivalent to 7 years and 9 months in a warm climate)

Audio Question
1) Yes. You will have to modify the wiring somewhat to install the later radio. There are not many wires involved, but if that frightens you I suggest consulting a professional. 2) Probably. The radio's final power amplifier is designed to drive a certain load. Generally this would consist of a single speaker with an impedance of 8 Ohms. If you wire two 8 Ohm speakers in parallel the effective impedance drops to 4 Ohms, which will draw twice the current at any given volume setting. This could over heat the power transistors in the amplifier, causing them to burn out. And yes, the best that you could hope for is two speakers producing the same exact sounds. As you put it "mono" not stereo. 3) I have no idea where to obtain speaker brackets for the right rear of the early cars. That side of the car is very cramped because the fuel filler neck and the expansion tank are hidden under that panel. There really isn't any room for a speaker there anyway.

Period correct wheels
Growing up in the rust belt, where American muscle cars were the only "sports" cars around at the time, the Cragar Super Sports are just about the only wheels I associate with that era. I remember the occasional "slot mag", but it seemed the Cragars were the popular wheel around here.

Every time that I have had trouble removing a cylinder head from an engine it turned out that I had missed a head bolt somewhere. (Sometimes that is easy to do if the engine was dirty.)

Turn the key, Just get a Click
I routinely purchase new bullet connectors at Lowes. (The mega hardware/lumber yard) The connectors that they carry will actually plug into the originals and vice versa. I am sure that they are less expensive elsewhere, but how many do you really need?

Ignition problem.
5,000 RPM * 4 cylinders = 20,000 sparks / minute 20,000 / 3 cylinders = 6,667 RPM Not a whole lot of difference really. The GM V8's red line isn't generally limited by the ignition module. At least not in the older cars that still used the HEI module.

What Z is this?
It has a solid hood. What makes you think that it is a 280Z? (Not that someone couldn't have put a solid hood on a 280Z, but it seems like there would be heat issues.)

1977 280Z Voltage gauge "Always On?"
I didn't realize that the voltmeter in the later cars was always hot. At first glance that would seem like a problem, however generally analog meters have an input impedance of 10,000 to 20,000 Ohms per volt, so with the scale showing a maximum reading of 16V that comes out to somewhere in the range of 160,000 to 320,000 Ohms. At 12V that calculates to a steady state load of 38-75 micro Amps. At that discharge rate it would take more than 10 years to discharge an 800CCA battery. So I would say it isn't a cause for concern.

Synchromesh worn out?
The cold is bad enough, but the salt on the roads is the real issue. And if you can get the type of adapter that Steve mentioned that would be a really good idea. I have removed and re-installed transmissions in my car three times already and it takes all the force that I can muster. I used a transmission jack, but the problem is that you still have to twist and pull on the transmission until you get the splines to line up on the input shaft. There is no room for error on that. They either line up perfectly, or they do not line up at all.

Datsun Z questions
Lucky? Steve, really... More likely you are: A. sufficiently knowledgeable to be able to maintain your own car (you are a retired Nissan mechanic aren't you? You are certainly a wonderful source of information on the intricacies of the fuel injection and air conditioning systems on these cars.) B. live in a state (California) where there are still a large number of good condition Datsuns available (Both because of the climate, and the mandatory air pollution testing that cars there must endure.) C. apparently were able to find one-owner cars (which has to help considerably) Many of us are stuck with rusty 30-40 year old cast-offs and are luck if we find one in rebuild-able condition. Back on subject, I personally prefer fuel injection to carburetors, when it is working properly. However when dealing with any 30+ year old car there are going to be issues with the old electronics and particularly the old connectors. In places where we have wide temperature extremes and high humidity you need to be wary of the electrical connections and wiring on any old car. The bad news is that wiring and connectors are at the heart of any ELECTRONIC fuel injection system.

Crankshaft pulley nut size?
The 4 bolts that you point to in your picture hold both the fan, and the fan pulley to the water pump. This is the "standard" arrangement in most RWD cars by the way. You should at least loosen the fan belt before removing these bolts. The reference to the crankshaft bolt being a 16mm bolt refers to the bolt diameter, not the head. The head requires a 27mm socket, but 1 1/6 works just as well, being 26.9875mm. The trick is that on the older engines at least, you need a 6 point socket. And the wall thickness of an impact socket will prevent it from reaching the bolt head. Since it is very difficult to find a 6 point 27mm non-impact socket in the U.S. the 1 1/6 socket is and easy substitute.

what after market EFI will work for a 75z??
Could your cold start injector be leaking? How old are the injectors? Have you checked for vacuum leaks?

L24 C110 - very low Voltatge to Coil
That sounds like a bad connection in the wiring harness. Check all of the connectors between the ignition switch and the ballast resistor, and double check your ground straps between the engine and the negative side of the battery. Somewhere you have a high resistance current path. (or possibly several.) Corroded or loose connectors can cause this, as well as bad splices.

Black smoke when heavy throttle..
Could the accelerator pump on the 4 barrel be set wrong? On a down-draft carb there is actually a pump that is actuated by the throttle to literally shoot a stream of fuel into the intake when you open the throttle. (Without this the mixture would lean way out until the system re-stabilized.) I had a friend back in the 70's who put some huge Holly "double pumper" with mechanical secondaries on his small block Dodge, and every time that he punched it from a stop light it would actually flood the engine with gas and the car would stall. (Followed by him spending several minutes with the hood open holding the throttle plate at WOT and fanning the carb to try to get the fuel to evaporate.) It is possible to put too much carburetor on an engine by the way.
