Never done a Mini, but the least fun I ever had doing a water pump was a G60 Corrado. Took a day and a half, and the "proper" procedure includes removing the alternator, supercharger and A/C compressor - so reclaiming the refrigerant and evacuating the system are supposed to be part of the water pump job. I did not open the A/C lines, which added several hours to the time.

I've heard the ZX fans (79-83) are a different thickness, and don't fit in S30s. But I would think that the 74-78 fan should still fit my '71. Just wish I knew for certain before I start looking for used ones.

Are all the plastic fans interchangeable? Can I use one from a 260 or 280Z? Or do I need to get one for a '72 240Z?

As I said, Dave, those boxes do work. Or at least they did in my past, so I assume they will today. I wouldn't think connecting them to a 240Z would be hard, although on my Series I the wiper parking routine might be an issue. Don't know if your '72 is any different.

I'd still be interested in finding out how heavy (or light) they are.

Since there's bound to be other things on my car that won't be stock when I finish it, I don't think competing in a stock class will be anything I need to worry about. But it's a good thing to remember.

Another common mod that eats more amps than stock is electronic ignition. And the internal voltage regulator in the ZX alternator is more reliable, and delivers a better regulated voltage than the stock points-type regulator. It's just a better system. But even better is that the alternator swap is totally reversible. Going to show the car and want to look stock for a weekend? You can restore it back to factory in 15 minutes or so.

Looks like it has potential, although the original engine and transmission are apparently long gone. #4633 on eBay

Garth is right, the alternator upgrade is a totally separate issue. The ZX alternator will help recharge your battery faster, and can produce more amps in normal driving. The internal regulator is more accurate and reliable as well. But it doesn't address the issues that Dave's harnesses do.

See details here: Thread in Parts Swapping

Thanks for the kind words, Dave. Your help and support during the trek to get here has been invaluable. These parts wouldn't be available today without your help.

The 240Z headlights work by switching the ground, not the power supply. So you have something grounding the wiring somewhere in the switch or it's connections. When the headlights come on with the switch, do they come on high beam, or low beam? (Or, heaven forbid, both?)

No, this is a good question. In my experience the 280ZX pulley should work fine, no need to swap it. You might need a new or different belt, but that should be all. If you've got any local wrecking yards that will guarantee their parts, you should be able to grab and go.

Just to clarify - these adapters are for 240Z's wishing to use the '81-83 internally regulated 280ZX alternator. Later 260 and 280Z's are not supposed to need these. Other Nissan alternators may work as well, but I can't confirm that.

At this time, probably as ordered. Depends somewhat on the demand.

The alternator adapter plugs are going to be available after all! See details in this thread: http://classiczcars.com/forums/showthread.php?t=20571

Good news in several ways! I've hooked up with a source that will make the "Plug-N-Play 240Z Alternator Upgrade Adapter" to my specs. And the production version is frankly better in many ways than I had hoped. 1.) It is now the small, weather-resistant and self-contained unit I had originally envisioned. (See pictures below.) 2.) It is made with a factory-style connector, and new brass terminals. The necessary diode is self-contained. 3.) Better yet, the final version is cheaper than I had thought it could be made. The final price is $15.00 each, INCLUDING postage within the US. Contact me for shipping outside the US. A small volume discount is available for quantities of 10 or more. Contact me for that as well. So here's the scoop - I can only do this via money orders at this time. PM me for the address to mail it to. Figure 7-10 days turn-around (plus first class mail delivery) once I receive payment. Here are the pictures, and the instructions. (Instructions will not be printed and shipped with the adapter, to hold down on costs. Please download it here instead.) The alternators that I know for a fact will work are from '81-83 280ZX, both turbo (70 amp) and non-turbo (60 amp). I've been told that other Nissan alternators may work as well (Maxima, etc.) but can't verify that. 240Z to 280ZX alternator.pdf

You have to remove the nuts. WARNING!! One of those wires goes straight to the battery. Make certain you have disconnected the battery before you start.

You could simply add foglights as is, but I think you'd be defeating the purpose of the parking light relay. The idea of the relay kit is to make MORE power available for the parking lights. If you then put more lights on the same circuit, they draw through the same relay and fuse as do the parking lights. It would be better to use another fuse and relay for any additional lights that you may add.

Hmm, maybe not. Here's one that is cheap, closes really soon, and has no bids.Metal fan and clutch on eBay

Thanks, guys. Sounds like the problem is real, even for a street car. I will use a plastic fan instead.

Is running the early metal cooling fan on a daily driver really a bad thing? I seem to have heard that it is hard on water pumps. Is it all that bad though for a daily driver? Or is it only a problem for sustained high RPM use?

Looks like a gold Panasport to me.

Probably won't pass the visual inspection in CA, even if the sniff test is within limits. Are there any Z headers with CARB exemption stickers?

I installed similar boxes in my cars back in the '70's. Yeah, they work. Shouldn't require too much in the way of wiring mods, IIRC. Never cared for the add-on look, even back then. I'll probably either use Rain-X or PIAA wiper blades (which have a Rain-X like coating on the blade) on my 240Z.
