Local Police Trying to Find this Man
2 pointsYears ago, at a party, a biker showed up. He would walk up to a gal and say, “I’ve got your name tattooed on my d***.” One gal challenged him, so he whipped it out. Sure enough, “Your Name” was tattooed on his unit. What an idiot.2 points

KUDOs to Ztherapy
1 pointReceived a package today with a couple gems inside. For the last month or so I have been chasing a lean condition just off idle on my 240 motor. Cold it was hard to start even while being choked, a condition I have not experienced since purchasing my Ztherapy carbs in early 2001. Trying all of the normal problem solving I finally did the “starting fluid test” and found that when I it sprayed on the rear side of the back carb the idle was effected. Closer examination I discover the shinny silver cap over the throttle shaft was missing and covering the hole definitely changed the idle. Engine ran good at 2500+ RPM. Steve at ZT called me back and we discussed the issues and he advised me the throttle shaft seal was probably blown out. (A backfire can do that). He offered check the carbs if I would send them to him. That day I UPS them off to him and in less that two weeks I received a package back. My 20 year ZT old carbs look brand new and based on the cost of a ZT rebuild kit the price was a steal. They are one of those companies that you can’t say enough good thing about. THANK YOU STEVE .1 point

Electric fuel pump wiring with relay and inertia switch
I have a 1976 280Z that was converted to SU carbs by the previous owner. The mechanical fuel pump was crap, so I replaced it with a GMB part which didn't seem to work very well. I replaced that with another GMB pump which seems to work fine. I am aware that some have reported problems with them, so I also installed a NISMO electric pump. In reading on this site about how to wire this up I saw lots of advice about adding an inertia switch for safety. From the FSM and wiring diagram I also learned that the factory fuel pump in my car was controlled by the fuel injection relay, which had been deleted long ago from my car. This article describes one pretty clean way of wiring in a relay and an inertia switch to provide power to a low-pressure electric fuel pump in a carb-converted 280Z. Background: In the 280Z the fuel injection relay is actually two relays packaged together: the EFI bible refers to these as the Power Relay and the Fuel Pump relay. When the ignition switch is in the ON position, the power relay sends sends power to the fuel injection system (ECU, fuel injectors, AFM); the fuel pump relay sends current to ... yep, the fuel pump. The current sent to the AFM doesn't power the AFM; rather, the AFM closes a set of contacts when the engine is running and air is flowing, and it opens those contacts when the engine is off. The current required to operate the fuel pump relay runs through those AFM contacts so that the fuel pump relay closes only when the engine is running and air is flowing. If the engine stops, the AFM contacts are opened and so is the fuel pump relay. It's a little more complicated than this (related to how the Start position of the ignition switch sort of overrides all of this so that the fuel pump can run in order to start the engine), but that's not really important for this discussion - I want the fuel pump to run when the ignition is in the ON or START position, unless I've been in an accident. It turns out, there's an easy way to do this. The connector that (formerly) ran to the Fuel Injection relay is part of the instrument harness and is found under the dash by the steering column. I just replaced the female 6-pin connector (only 4 pins are used) with a similar one from Vintage Connections and then wired the male part to the Ford-type inertia switch and Bosch-type 12VAC 30A relay as shown in the diagram and pictures below. I just mounted the relay and switch to a piece of 2mil aluminum plate, and mounted the whole thing by where the ECU was located. It seems to work: the fuel pump comes on with the key in the ON position, and if I tap (well, smack) the inertia switch to get it to open, the fuel pump turns off. I haven't driven it enough yet to know whether the inertia switch will "break" when I don't want it to (going over bumps, etc.), but it's easily reachable from the drivers seat.1 point

1 pointThat's what I get for reading posts on my phone and using my old bifocals. It sucks to get old. The alternative is worse. Anyway, that drier can be tossed. I suspect it really wasn't sealed tight, considering the duct tape, so it has seen more than a lifetime of moisture.1 point

engine compartment color
1 pointCount me too on body color. That's the first thing I notice when I see an open hood. Black is a negative, something was done at some point to this car, half way kind of job. I've used a small HVLP cup gun from Harbor Freight with good results. $15 well spent. I could dial it in to a pattern no bigger than a thumb tack. Still have that little baby!1 point

engine compartment color
1 pointAgree, body color. I feel like black makes the engine bay too dark and thus more difficult to see things (including leaks some times), I've always thought body color looked more finished. 🙂1 point

1 point+1 on the return to body color option. You'll have a choice between single stage (like OE) and two stage processes, choose one to best match to current body finish. Going with body color will give the various engine bay bits the best opportunity to be seen.1 point

No oil pressure after rebuild
1 pointOK, I will convert this stuff to it's own thread when I get a few more minutes to make it read right. In the meantime.... I have more pics. Here's a pic of one of the gauges. You can see the two different heating coils wrapped around two different "U" shaped bimetallic strips. Interesting to note that internets research indicates that "U" shape is part of the compensation as well. The concept is that the unheated side will compensate some for changes in ambient temperature. "They say" it doesn't get rid of all of the temperature based effects, but it helps some. Between that "U" shape and the compensation stage, the gauges seem to be really stable. So this is an example of the compensated gauge with the two stages: And here's a closer-upper pic of the compensation stage showing it's parts: The switch opens and closes to keep the temperature of the compensation strip at a constant temperature (ave). If you put a Voltmeter on the sender unit, you'll see that it isn't a steady voltage, but is instead a square wave.1 point

Trouble Downshifting to First Gear?
Let me chime in on the transmission FILL and DRAIN plugs... (begin rant) I have no clue why people tighten these SO TIGHTLY! It's un-necessary. In my former life I was a licensed Journeyman Plumber (Ret.). Actually, I guess I still am a licensed Journeyman Plumber - just not employed as such... What in the crap does this have to do with transmissions you ask?? THOSE PLUGS ARE PIPE FITTINGS (well, they have pipe threads...) So, now that you know that I am eminently qualified to speak on the subject: - Go the Home Depot. Plumbing Department. BUY an entire roll of TEFLON TAPE. - Go home. Properly apply (ya, just wrap that sucker up with tape) the teflon tape following the manufacturers directions to the male threads of BOTH PLUGS - BEFORE you install them. - Tighten the plugs (BOTH PLUGS) ONLY ENOUGH so that they don't leak! There is NO pressure inside the transmission (like there is in your Natural Gas line or your galvanized water pipe) SO THE PLUG DOESN'T NEED 80 FT/LBS OF TORQUE. Seriously, you can practically screw them in by hand if you use teflon tape or good pipe dope (just kidding (exaggerating really) you need to snug them up.) But you really, really can stop over tightening those plugs. How do I know? Come and remove these plugs from MY transmission. Be a plumber - even if you don't want to - for me... (end rant);1 point

Just Another Damned Z Car Project Thread
Here is the engine. As I said above, Rebello 3.0. The cam is 27C-9, which I don’t know what that means in terms of lift and duration but I had asked Dave for a EFI street motor with some grunt. The compression is 10.2:1 so that cam will have to bleed off some compression for pump gas. The car will use a Haltech Elite 2500 for brains so you know I follow Duffy Mahoney every time he posts!1 point

My two swiss S30Z Fairlady Restoration build thread
Yeah it has been a while since i worked on the car myself. but i decided it's time to assemble all t he small bits and pieces into "subassemblies" whever possible. Last week i worked on the moustache bar. So here we got the puzzle in single pieces: The powdercoating company also coated the inside of the bushing shells, so i cleaned them with the dremel tool Added som fresh Bushing grease: And in with the new bushings And all hardware combained. ready for installation. It looks like a simple thing, but if you think what work went into it: - Everything had to be disassembled from the car first - The moustache Bar got sandblasted - The bar got primered and powdercoated - Old Hardware fasteners got cleaned (in the rattler), zinc plated and yellow passivated - New OEM Nissan Locking nuts and washers ordered and added - New Polyurethane Bushings with bushing grease Hope to find some time for some other work again soon, it's fun after all ?1 point

Non-Dilbert Engineer Joke
1 pointThanks to @Dr. 240Z An Engineer dies and goes to Hell. Dissatisfied with the level of comfort, he starts designing and building improvements. After a while, Hell has air conditioning, iced water, flush toilets, and escalators, and the Engineer is a pretty popular guy. One day God calls and asks Satan, "So, how are things going down there?" Satan says, “Why, things are going great. We've now got air conditioning, iced water, flush toilets and escalators, and there's no telling what this Engineer is going to come up with next!" God is horrified. "What? You've got an Engineer? That's clearly a mistake – he should never have gone down there! You know all Engineers go to Heaven. Send him up here immediately!!" Satan says, "No way, I really like having an Engineer on the staff. I’m keeping him." God says, "Send him back up here or I'll sue you.” "Yeah, right," Satan laughs, "and where are you going to get a lawyer?”1 point
