Never mind. Blew it up myself, looks like an r200. Somebody already converted to R200. I think, based on the lack of side bolts. Ask for the half shafts too.

It's an R180 isn't it? Stupid Facebook photos don't blow up. Can't tell. 1972 240Z.

AydinZ71 is right, I didn't look at your picture. You already have it. Your drive (propeller) shaft will work. The distance for an R180 and an R200 is the same. They are the same length. One area where you can get screwed up is if the R200 is from a 1975 280Z. For whatever reason Nissan used a different bolt pattern for the pinion flange in 1975 only. If you can find out it might save you some trouble.

The Facebook R200 seems like a decent deal. Axles, half-shafts included for $200. Probably close to what you'd pay in wrecking yard prices today. I mentioned gear ratios in your other thread but with a V8 you could probably use a taller gear anyway. The torque doesn't need the low 3.9 and you'll get better cruising RPM with a 3.54. You only need an R200 diff mount and the curved cross-piece for the suspension drop-downs(to clear the bigger diff cover) to complete the package, I think, but should probably get something like the Technoversion RT mount to handle the power, if you don't have one already. https://www.technoversions.com/DiffMount.html Here's your other thread.

You might need the halfshafts too, depending on which R180 you have, can't remember the details. Easiest would be to find a 76-78 junked 280Z and scavenge the parts. Sometimes you can get the whole car for less than the collection of parts. If you have to piecemeal it, the 280ZX's up 1983 (including) use an R200. Some use an R180 so you have to check to be sure. Check the ratios also. You might have a 3.9 now, but many R200's are 3.54.

Did you get new parts or used? The E12 modules are old and failing. You can use the red and green wires in the ZX distributor to run a GM HEI module.

Scroll down to the April 10 post here. Should have done some reading before you ordered. He is incommunicado. Good luck. Cancel that credit card charge if you can. S

Sounds like the stator or magnet or pickup coil in the distributor itself is broken or the wires have shorted. Download a 280ZX FSM and look in the Electrical chapter to see how to test those parts, or disassemble the distributor. In short, you probably have a bad distributor. Is it used? The bushings wear out in the ZX distributors, allowing the reluctor wheel to hit the pickup coil points. Here's a good description. https://www.atlanticz.ca/zclub/techtips/distributorrebuild/index.html

Just curious. What about the other guys? ZCarDepot and SilverMine? And Chequered Flag (Joe@ModernMotorsports's business)?

Maybe he needs another reach out. It's been almost 6 weeks.

Edited - the credit card charge challenging process requires oversight. I don't think that it's a given that the consumer always gets their money back. It's a process. If it was a U.S. business you could sue them in small claims court, report them to the attorney general in the state they are registered in, and also report them to the Better Business Bureau. Those are all remedies/actions for the consumer to take against companies that do not fulfill their obligations. Which is what Whitehead is doing here. But they're in Canada and the US Attorney General's office has a lot of other things going on right now. If a business needs a loan they should go to a financial institution. Whitehead has taken this person's money and is using at as collateral for loans or to stay afloat, paying their own bills. Often, what is happening here is a precursor to bankruptcy. Business will take consumers' money, use it to pay salaries, etc., delay as long as possible, then claim bankruptcy, leaving the consumer screwed. As JMortensen said though, there is a time limit. That should have been a sign, that Whitehead was stringing you along for a reason. They know about the time limit too. All in all, it's not a good sign. Looks like Whitehead is in trouble.

Why didn't you just use the stock valve covers? Didn't you still have to redo things with the taller Holley cover? Just curious. What is the benefit of the Holley cover over the stock cover in the first place?

The wiring diagram might help. Looks like both wires get power so turning the key on won't tell you anything. One wire is the ground for the CSV and the other wire is the power to the internal heater in the thermotime switch. If you still have the bullet connectors in the harness you could use those to figure it out. One pin of the switch will have resistance from the internal heater (the curly line in the drawing). The other one will be very low resistance since it supplies the ground for the CSV through the switching portion. Measure resistance through the pins to ground, then connect the male bullet wire to the one with low/no resistance. Or, disconnect the CSV, turn the key on, and the wire that has power will be #47, from the relay. Which is connected to #45 at the terminal and would go to the side of the switch with resistance.

Just go ahead and start a thread with a big For Sale in the title. If it catches someone's eye they'll follow-up, if not your diff will get sold. You paid, so you have a legitimate usage of the site to sell parts, per the agreement as a member. Not really sure what's happening with the site. I think that SuperDan has lost interest. Or maybe something has happened to him. Classiczcars.com has a Parts for Sale page, and they like LSD diffs too. Good luck.

I think that what you're proposing is not the way that most people would get to a larger booster. Which is really all that you're trying to do. Swapping to a completely different pedal box to get a bigger booster seems like a more difficult path than necessary.

This part sounds like a failing ignition module. They overheat and stop working then start working after they cool off. Often they will stop working after getting the engine up to higher RPM. That's one way to test it, run it up to high RPM, watch the tachometer needle for weird behavior and see if it keeps running. This part is normal. Those lights are supposed to be on when the engine is not running, but the key is on. They should both turn off when the engine starts.

It's been two days and the people who donated still haven't been acknowledged. The site seems to be on autopilot, nobody's at the helm.

@tube80z or @SuperDan can fix it.

Put some jackstands under the rear control arms, start it up, and run it through the gears. Don't do it with the wheels hanging the u-joints will probably bind from the angle.

That's going to be a 3.54 ratio open diff. Not even close.

Here's a sampling from a commercial vendor. https://whiteheadperformance.com/performance-parts/datsun-240z-260z-280z-parts/240z-260z-280z-r180-r200-diff-differential-lsd-limited-slip/

I've never done it but I've seen that most of the big cam shops can recommend a cam based on parts and plans. Probably also the drive gears and other odds and ends. They want people to call. https://www.compcams.com/products/comp-camshafts.html

Actually, 76 does have a top gear switch actuated solenoid that controls the vacuum to the vacuum advance module on the distributor. One of those emissions things. There are a lot of different 5 speeds out there. Some of the ZX 5 speeds have neutral, top gear, reverse, and overdrive switches, at least the FSM says they do. I removed my top gear solenoid when I got a 5 speed and just let the vacuum advance happen in all gears. Ran great. Just connect the hoses or run a new one to the same port on the TB. I think I've seen it described somewhere in the FSM but can't find it. It's in the wiring diagram also though. Underlined the two parts connected.
