Seiko Watch CorporationThe Datsun 240Z and Prospex Speedtimer: New collaboration...

I'm just learning what's what. I have near-zero electrictronics background but I am handy with a soldering iron and recently bought an oscilloscope to learn on (Tektronix TDS 1012) I can see that the WMIC labled parts are all metalized polymer capacitors and the resistors I recognize are pretty common...but the ICs? Are those the silver 14(?) pin guys with the heat sinks? And what the heck are those copper-coil towers with blue things next to the plug? I need a magnifying glass. I can't read 'em. Nothing looks like a discrete transistor that I recognize, but the round caps on the side say NEC...so I guess that would be those? When I was running the car previously I've grabbed the harness connector and given it a good hearty wiggle with no change but today when I did the second "tap" it was on the plug and not the unit itself, and it went off like a switch. Mostly though, when I tap it with my foot it is on the lower metal bracket. Tomorrow I will be sure to try and move/wiggle each bit of the harness from the connector up on into the dash and see if that makes any changes.

Roo, Nice work on the brake stuff. I have a couple comments / questions about the master cylinder: First, where did you find the rubber seals you used to rebuild the master? Second, the pistons originally had a black oxide coating presumably for friction reduction and/or corrosion protection. It looks like you hit the pistons with a wire wheel and burnished that coating off? Any thoughts about having them recoated? And last, a little pedantic, but I'm thinking that is not quite the correct master cylinder for a 5/70 car. I'm no expert on the early cars, but I think you should have the one with the ground and stamped "F" and "R", not the cast-in markings. The correct one I believe would look like this: There was some discussion about such matters here >> https://www.classiczcars.com/forums/topic/65579-brake-master-cylinder-46010-e4602-up-to-91971/?&page=3

Hey All, I hope someone can help me out, this is a rehash from another Z forum, but I'm spreading it in the hope of finding a solution. I'm in the early stages of restoring a 71 240z and thought a chassis jog would make life easier. As of now, step one is creating headaches, as described below. As of now i have built a chassis jig/frame and am in the process of bolting up my bent 240z to it. And here is the rub. I spent countless hours pouring over the only chassis dimensions document out there. That being the BF-3 204z dimensions PDF. As described previously I was thinking that the dimensions are wrong, or my car is very, very bent. With what I describe below, I don't think the car can possibly be 'that' bent. Some framing of the problem, with a crap pun: I have used four mounting points (described from rear to front): (1) Rear diff mount (not mustachio bar), (4 lateral bolts) (2) Front mount to the rear lower control arm, (4 lateral bolts) (3) Transmission mount, and then (two lateral bolts) (4) Front Strut Tower Top ("A" point). The dimensions (that don't work): (1) Reference point. (2) 465mm from ref. (1). this one is 15mm to short. (closer to 480mm) (3) 1427.5mm from ref. (1). This one lines up. (4) 2381.3mm from ref. (1). This one is 20mm to short. (closer to 2401.3mm) To my point......what the heck is going on here??!! Between point ref 1 and 2 my car is 480mm. In the BF-3 document, there is no reference to a 480mm dimension.... The car cannot be warped by 15mm, it's all structural mounting points. So, what am I missing? Moving on to the dimension between 1 and 4. Again, too short by 15 to 20mm... So, what is the actual dimension? All of the lateral dimensions are correct. I scratch my head. It's great though as it gives me something to talk with my wife about over dinner. Thank you in advance!

I'd love to have quick jacks, but I've used a set of standard plastic ramps for a couple of decades.

I've used common jackstands for years. )n the 280ZX in both front and rear there are obvious places which can support jackstands. In the rear, I slide a floor jack under the differential, lift on it and place jackstands under the places in front of the axle where the suspension bolts to the underbody. it's not hard to find stout places that can support the stands. What the factory manual says aren't the only places you can support the car if you're thoughtful about it. In front on my 280ZX, I slide the floor jack under the cross beam beneath the engine, then position the jackstands under the stoutest place in the frame rails with a chunk of 2x4 on top of each jackstand to spread the weight out. On my 280ZX I jack up the front first, then the back. It's low enough that getting much of an angle on either end makes it hard to access the other end. you may have to slide the jack in from the side, not the front or back. Lift carefully. Push on the car and make sure it's stable. Push on it after the jackstands are in place, and double-confirm that it's stable. Patience and thought will yield a safe result.

What a load of rubbish, there's no way the ball can wear out that much! The Japanese engineers that designed that part knew enough about metallurgy to design the part so that never happens. The cheap stuff now coming out of some countries may be a different case, but not the originals.

I love the claims about patents considering that design is very common.

Your hard starting issue sounds like a problem with the fuel mix not being rich enough. Are you using the choke when you start it? Make sure both jet tubes under the carb get pulled down all the way when you pull the choke handle back all the way. Check that the fuel mixture nuts under the carbs are turned down 2.5 turns at least, and that the float levels are correct.

Need both sides

Location and price of the turbo engine

Perfect thank you guys for confirming that for me. Just on the topic of "new" systems and "old" systems I'm currently limited to the Legalis R exhaust pipes product number 750-15414 from fujitsubo themselves and the super Ex headers (510-15037) just to make sure these are the ones that would fit as I didn't know there were older or newer version of the exhaust. see the images for reference

Still don't know what's wrong with it? ;-) Every (good) carparts shop has them!

That was me that posted that photo to show him how a cracked or broken guide could cause an oil problem on one cylinder.

I apologize to @Sean Dezart You had bad contact information.

I ordered one of these plates for one of my ashtrays that was missing one, very nice piece. Quite close to the OEM unit, the only difference I could see is the reproduction is a flat piece, whereas the OEM slotted plate has a small rounded lip around the edge, at least compared to my other ashtray. Both ashtrays are from mid-1971 cars, in that transition period between original series 1 cars and later ones, if that matters. Fitment-wise, the "blade" part sits a little bit lower than the OEM unit per the attached pictures, but overall I'm very happy with the replacement. My ashtray is also missing the spring clip on the outside that I need to figure out now, along with finding a replacement for the pitted chrome rings around the lighter hole. Thanks @Chris Holt for your efforts!

I bought an N42 that had been in machine shop jail for a few years, guy never came back for it and I paid maybe $200 for a newly rebuilt head with an oiler cam installed. Put it on and went about 5 miles and the god awfullest noise came from the valve train. Limped back home and found a lash pad had come off. Thank goodness there was no damage and @Jeff 78 280z talked me down off the ledge, told me how to fix it and I've not had to look back. Runs great every since.

I have wheel and tires sets for 240z, 280z, 280zx, and 300zx cars. Some sets are OEM and a few aftermarket wheels. Most are in great condition. I set of early z cylone wheels not so hot Let me know what your looking for and I will let you know if I have it. Pick up only in Northeast NJ. Will be posting pics in the next few days. These have been in storage for 20+ years.

Thank you Gav.

Adding an update here: I haven't found the root of the issue. I keep the car at my parent's house, so it's not always easily accessible, but I'm thinking that maybe a brake line got kinked a bit during installation. I plan to check those next. If I don't find anything there, I will switch to the old booster and see what, if anything, changes.

So it's been awhile since I last posted. Remember that aftermarket ECU? I found out it was bad and causing starting issues and the high idle condition. I happened to find an original replacement ECU from another 1976 2+2 and that solved my problem. I also found that the TPS was missing a screw and out of position on the throttle body. As it turns out, the missing screw had broken off inside the throttle body. I was able to source a used one and installed it. Everything now seemed to work except for the temperature gauge. This was baffling to me since I had replaced it with a new one when I replaced the thermostat and the housing. However, that one was a two piece unit. I tested the temp gauge and wiring by disconnecting the connection to the sensor, temporarily running a wire from the the connection to ground and turning the key to the on position. The gauge needle moved from resting position to max within a few seconds, eliminating the possibility of a defective gauge or wiring. This was reassuring, since I was not looking forward to having to troubleshoot a wiring issue, nor did I want to have to go and try to find another gauge. So, I purchased a new temperature sensor, this time a one piece unit. I had some free time to install it yesterday, and Voila! I once again have a working temperature gauge. Here's the one that didn't work: Here's the one that worked: And the proof:

Thank you! Oh there's rust in it, not too bad though in most places. I think that under the hatch sill is probably the worst of it.

It says on BAT and other places...🤣 https://www.facebook.com/marketplace/item/4161254077491653/?ref=browse_tab&referral_code=marketplace_top_picks&referral_story_type=top_picks

Good song I heard in a movie with Harry Dean Stanton, "Lucky". Weird movie but he was weird guy in cool way in all his movies.
