I, personally, wouldn't install just one piston but I have seen it done and working. Make sure it's the same piston as you already have in the other 5 cyl. Don't get the P90 head unless you want to lower you compression. Look for a P79 like Keith suggested. If your head (N42) is okay I'd use it since you wouldn't really notice much difference without other modifications.

You've changed carbs and you've even changed engines! I would stop blaming either at this point. Get back to basics. Fuel, spark, etc. There are no 'phantom' issues. Everything has a cause. You have changed a lot of things around on that car and the more you change the harder it becomes to diagnose. It sounds to me like it's ignition related but like I said with so many changes, I would go back to basics and try to eliminate the possible causes one by one.

AFAIK, the Pinto did come out in 71. I had one. Their recall and subsequent repair was to put a plasic shield behind the tank. In further tests, the shield also burned in the explosion.

If you're going to change the ignition relay, I would go to a self service junkyard and get a couple of them from there. I say a couple because that chances of them both being bad are slim. They'll be cheap because they have no clue what they are. Try them to make sure that is your problem. That will save you from paying Nissan's price if the problem turns out to be elsewhere.

Is your 79 ZX f.i. or carbs? I only ask because I don't know at which point the Aussie cars became f.i.

daddz, I really can't break the music down by the car I'm driving. The car isn't listening to it, I am. Since I was born in 1950, my musical influence would be basically the 60s and 70s. I like pretty much anything from those eras. I get somewhat selective when you start talking about music from the 80s, 90s, and 2K. I don't like rap/hip hop or anything that even resembles it. Drinking and driving or for that matter drinking alcohol at all has no appeal to me. (The 'Deacon Blues' comment) But back to the original statement, remember this was about a car that hit the scene at the onset of the 70s.

I guess we haven't established what kind or year Z he owns.

And you guys tell me not to be mean!

Sylvania Silverstars are much brighter than stock, cost less than H4s and plug right in with no modifications. I use them on my dailly driver 810.

The second picture show the relays and identifies them. Remember this is for a 78. I'm pretty sure that it's the same but compare the picture to your car to be sure.

Okay, here are the pictures. The frist one shows the location of the relay bracket which is above your fuse box on the passenger side. You'll have to remove the panel below the glove compartment.

When that car is right it need no gas to start. By 'more gas or less gas', I assume you mean that you are stepping on the gas pedal to start the car. It has a cold start circuit and the fuel pump is self priming.

I don't know if it would be the same as your 76 but I can attach a picture of the relay bracket from my 78 FSM. Does anyone know if there would be a difference?

I like the 'original' rear strut tower brace in the 72 and the 'original' dish mags. The 71 even has the 'original' orange accents on its wheels.:classic:

Don't vent it, that's actually illegal in some states. If it is R12, and it must be unless your 73 has been converted, it is very expensive. Unless you have a leak, it should all still be in the system. It can be captured but you need a tank and someone with the expertise. Call around and see what an a/c specialist would charge to do that. You'll probably have to pay for the tank and his labor but I think the freon is worth keeping.

Phyte, are you sure you meant to post that on THIS site?:eek:

I DON'T THINK SO! LOL

My bad!

It occured to me that I had read a similar thread here last year. So I searched and found it. Mike started a thread called 'Driving Music' last May. Reading through it I came wonder how we could have gone this far without mentioning ZZ Top?
