Is that directed to me? I was there and he was there. Don't know that it makes it an honor but it was cool to see him. I don't know how much into Japanese cars he is but this is what he drove to the show: Leno's 1967 Mazda Cosmo Sport 110S

So far, there's not much posted here that I haven't done or at least some variation of it.

He makes good wax though. Meguiar's (correct spelling) is all I use. Here's the back of his head as he interviews Jay Leno at the recent Japanese Classic Car Show:

Nah, wrong bolt pattern, won't fit her Z:classic:

dogma420, first of all, thanks for the compliments about my car. It's no show car by any means. I do my best to keep it clean and mechanically/electrically sound. As far as the four speed/five speed thing goes, I done quite a bit of research on them. Not only the Z/ZX/Maxima trans but many of the 4 cyl transes as well. And I've had several of them apart. You would be hard pressed to actually feel the differences in ratios between a 72 four speed and a 77-79 five speed. The differences are slight and perhaps this is why people contend that they are the same but they are not.

They're the same size.

m4xwellmurd3r, I'm wasn't knocking your car in my earlier post, but it has problems, as mine once did and it took a while to sort them all out. Hell, they're 30 years old. I was just saying that BuDavid should base his choice, 240 or 280, on what their potential is not their quirks which both 240Zs and 280Zs, as well as 260Zs have. When they're right, like any car, they're pretty darn good.

Well the Zhome article is ......... WRONG! Sorry to whomever that offends but wrong info, and there is a lot of it out there, tends to become the 'truth' if enough people read it and repeat it. Read the last line in my signature (thanks to Jayhawk) If something doesn't quite seem right to me, regardless of what others may say, I try to seek more accurate information rather than 'someone told me' or 'I read somewhere that...' etc.

No arugument intended but if there was one the manual wouldn't be of much help either way. I was just giving facts. If you want to argue with facts, that's up to you. Those numbers from the owners manual are pretty general. 38 mph with a 3.592 first gear vs. 38 mph with a 3.321 first gear wouldn't make enough difference to make a change in the manual for four speed vs. five speed.

Compare them on this chart:

First off we'll deal with the last comment. WRONG! The four speed and 5 speed do not have the same ratios. 1st, 2nd, and 3rd are all slightly higher in the 5 speed. And there are three different overdrive ratios in the 280Z/ZX five speeds depending on which year it's from. The 5 speed was never standard until the ZX. It was an option on the 77-78 280Z. (in the US) I agree with Arne's comment about bumpers but that's just my opinion so nothing else needs to be said there. If your pre-pump filter is filling up with crud, you don't need another pre-pump filter, you need to drop the tank and either clean it or replace it. In fact, when everythinig is right, you don't even need a pre-pump filter. Cleaning the connectors is never a bad idea but that won't help your tank. If you think driving with a dirty gas tank and changing the filter every now and then is untimately going to solve your problem, I think you'll be dissapointed. BuDavid, I'd throw out his example of a 280Z as any kind of a basis to decide between the 240 and 280. A properly maintained 280Z doesn't exibit any of those problems. Nor are they "less stable at high speeds because of the big front bumper" as earlier stated. And the other statement: "it's very sensitive to vacuum leaks and corrosion on the connections" would apply to any car that has ever been built. The key is proper maintainence. My 78 starts and runs whenever I get in it, doesn't crap out an 4000rpm, doesn't wander at high speed, doesn't fill up the fuel filter with crud, etc., etc.

Rick, I have the same differential in my 78. It's the standard differential for a 77-78 manual trans S30. Unless you or someone else changed it, it's not a LSD.

I'm still betting on the tank being bad. I experienced that same thing when i purchased my 78. Cleaning the connections is always a good idea but the tank is the logical problem considering the car hasn't been run in 7 years. You can't really check any of the other components properly until you have the car running. My injectors were fine. Once I had a good tank on my car, the only other things I ended up changing were a couple of fuel lines, fuel filter, and the cold start valve. Everything else worked even after sitting all of that time. I'm going to go up and help him the first chance I got. I'll bring a can of starting fluid, my test equipment, some tools and my portable jumper.

I rarely see the factory alloys on a Z. I have them on mine and when I searched around to find a replacement for the one that had curb rash, it took over a year to find a satisfactory replacement so I guess they're not that easy to find. The one drawback is that they are only 5.5" wide but I have 22560's on mine and haven't had any problems.

Thanks, that's what I was trying to describe.

I stand corrected. The dogleg is the 77-79 200sx/78-79 510 5 speed. You did say truck trans. That would be the normal shift pattern. 1-4 same as the 4 speed with fifth above reverse. The dogleg has reverse at the top left with 1st below it and then across the gate and up for 2nd, down for 3rd, across and up for 4th and down for 5th. The truck trans has either a 16.7% or 18.7% overdrive depending on the year which is better than the dogleg but still not the 25.5% like the 81-83 ZX/81-84 Maxima trans. The 79-80 ZX tranny is actually the same as the 280Z 5 speed with only a 13.6% overdrive. You want the 81 up for the best overdrive.

Mohamed, don't misunderstand. All I really meant is that you have the experience to know how long to apply voltage to the injector and Corraro is inexperienced with the EFI system. He probably doesn't know the fine line between testing the injector with 12 volts and destroying the injector with 12 volts. You and I both have the experience to know the difference. And I'm just making sure that he understands that. I have no problem understanding your English. My family is from Guyana, South America so I've had a lifetime of hearing English that is different from what's considered to be normal in the U.S. I understand what you say better than I understand some people that were born and raised here.

Those are 15 inch ZX Turbo rims. Some people call the the 'Swastika' wheels. I really dont understand what he's saying about the injectors. Corrao, did you unscrew the injector holders and lift the entire rail with the injectors intact? If so, why? You could have tested the injectors (lose that term 'shock') without doing all of that. If you mess up those insulators when you reinstall the rail/injectors you'll have leaks that you didn't have before. If you put power to the injectors with the rail in place you'll hear a click. Like I said before, and I have a lot more experience with this than the others who have responded, don't put 12 volts to them. I don't care how many times BuDavid says he's done this. He also has more experience than you. 12 volts on those coils inside the injectors for too long will fry them and you will need to buy new ones. I'm betting that there's nothing wrong with your injectors and you're presently involved in doing some needless work. Don't make it worse. Put it back together if you haven't screwed it up already and TEST THE FUEL PRESSURE! 7+ years of sitting with gas in the tank is your problem. The car will not start without adequate fuel pressure.

Er...that sounds kind of like the the gist of the original question.....

Truth is that at this point he shouldn't have unbolted anything. Testing would have been the proper way to go. Ripping things apart before you know what the problem is only leads to spending unnecessary $$$$$.

A stock flywheel weighs 23-24 lbs depending on the source. Even the Y70 810/Maxima flywheel weighs 17.6 lbs. I weighed mine so I know that for a fact. 13 lbs sounds like the Centerforce. Is that what you have? And to answer WinZro's question, a 7.245 lb flywheel would be tough to get going from a dead stop in normal traffic. It just wouldn't generate enough inertia and you have to really bring the rpm up to get it underway.

These are my home made injector test tools. They're simple, they work and I've never had any problems with them. The one on the left is self-explanatory and the one on the right if you remove your injector connector, place it on the injector and place the connector on top, it will show if you have a signal to the injector while cranking or running the engine.

GreenZZZ, you're talking about the 'dogleg' five speed. It's only a 14.6% overdrive and not really sturdy enough for a 6 cylinder engine. I have that trans in my 64 L320 pickup behind a 4 cylinder engine. I'd go with the five speed from the 81-83 ZX or 81-84 Maxima. It's overdrive is 25.5% and it's designed for a 6 cyl. You can still find them but you have to look. I bought one a couple of months ago for my 810 at the junkyard.
