    Which engine for a 77’ 280z

    Wow... I'm really outnumbered here. The L28ET is an incredibly stout and reliable engine. At $400 it's an absolute steal! (at $500 it's an absolute steal...) I wish I were in a location that I could pick it up! You don't actually need to do anything to it to get cheap reliable power. If the cam looks good and the engine is relatively clean you're set. The turbocharger is NOT scary - run stock, they last nearly forever. From the factory they run about 7 pounds of boost and at that setting they'll run forever. (most people forget that turbochargers were originally built for aircraft - an avocation where they have to be as simple as possible and extremely reliable...) Run stock, you can drop the engine in with little fuss and you'll have a strong dependable power plant. The stock ECCS engine management system works very well - as long as you keep the engine stock. If you modify, you'll probably have to look at a tunable engine management system. It'll take a bunch of $$$ to craft an N/A engine to come close. The L28ET is cheap power... Also remember that 80% of the L28ET's were mated to an automatic transmission The weak spot: You'll need to focus on the engine (ECCS) harness. BUT, you'd have to do the same with ANY early EFI engine harness! They just weren't built to last this long. Most of the problems are due to oxidized wire and connectors that will skew the information the ECU needs to run the engine properly. A new harness makes a world of difference - that's what NewZed has seen me comment (complain / warn) about. Now... The problem with a turbo engine is it turns many people into boost junkies. That's where the charge pipe, intercooler, blow off valve, bigger injectors, fuel rail, adjustable FPR, bigger fuel pump, new fully tunable engine management system, coil-on-plug, wideband, blah, blah, blah comes from. That's also where you see guys blowing turbos, melting pistons - because they don't know what they're doing. I daily drive mine. Have for the last 9 years.

    My son chides me for not using a sanding block at times (uneven pressure when you're using your hand - it's not flat...). I like to start by hand - I can feel debris that will scratch more than the 1500 or 2000 grit under the paper that way. When I feel debris I immediately wash it away from the paint and paper. Once I've gone over by hand I start using a block for flatness (then I usually give it another quick once over by hand... OCD). I cringe a little when I see machine cutting. Every time I've tried that I end up with deeper scratches than I want and I believe it's because debris gets caught in the grit - but you'll have no way of knowing it until you're buffing.

    restore plastic lense

    We just use our buffing compound and orbital buffer with a foam pad for plastic lenses. No prep and they polish right up... For rubber, vinyl, and plastic - Mequiar's Hyper Dressing.

    Taillight panel paint

    We had a 1975 280Z "Museum Car" in the shop for a few weeks a few years ago (4500 original miles, then kept in an auto museum in PA - shipped from the museum to our shop...). The color was actually much lighter than I thought the original color would be (it shows a tad darker in these pics than IRL- the top of the license plate light actually shows the color best - that's not merely "light flare"). Here are some crappy pics I took of it:

    When the grommet is still black it's a lot easier to see. :) Who made that harness for you Q?

    AZ auction action

    I had to look at that link - I was sitting in the auction hall when the '76 2+2 was on the block. I also had a chance to see it on the paddock before it went in. The engine bay that I saw today looked nothing like the pictures on the site - it was, well, less cared for... The car ran quite poorly - just as I've seen with other stock early EFI Z's that haven't been gone through. The interior was complete and quite nice, as was the paint. The final bid was $40,000. We also saw the Orange 1973 on the block just a few cars before the 2+2 and were quite amazed at the $37,000 final bid... It was a nice example of a '73 with original engine (with SU's). The interior and exterior looked much better than the engine bay. The hatch glass had vertical defogger lines. Radio was not original IIRC. An Auto Transmission car like the 2+2... Personally I was surprised by the two Z's I saw at auction today.

    original blue engine paint colorcode?

    We came upon a well preserved part that we took to a local paint supplier and had them match the color. We ended up with a quart can (from which we've done probably 5 blocks over the years and still have more than half) and eventually a couple of spray cans they made using that formula. We discovered that it's much easier to brush on than spray the block itself... Easier to spray the brackets and pulleys. We also learned from the 1975 Museum car we had in the shop that if you're going for authentic factory look when spraying, you have to overspray the bottom of the head about an inch or so...

    New house, bigger Garage!

    Poop brown? (Sorry, Poop Brown Metallic...) That's my car's original color. Guess there were a lot of those...
  9. No, the needle sits at the center point without voltage or current. I have one in my hand (and I'm not sitting in a Z...).

    Dec. 260z door windows parts

    No. I think you need to adjust the forward channel - the vertical channel that the nose of the window travels in at the front part of the door. That's assuming that you've already cleaned and re-lubed it (and all your other channels). You might also check the nylon guide at the nose of the window frame to make sure it's not cracked or broken and is still properly attached. If the window doesn't stay level while you're rolling it up (tilts forward or tilts backward), that's the small channel near the rear of the door. The FSM shows how to properly adjust. The trick is to get both of those channels adjusted in the correct position so that the window moves smoothly and stays level as it moves up and down...

    Oh, I wouldn't use tar to plug off that water port to the carbs... 😉 😂 (How much tar can you get for a "Ha'penny"? - wait, where can you get a Ha'penny...) And it's probably BPT but over here, we just stuff an American NPT plug in holes like that.

    window regulator

    No, It came with the change of interior style between the 240 and 260. My early 260Z has the same regulator used in the lates and '75-'76 280Z. Then there was another door change with the '77-'78 and the regulator changed again...

    Ya. Jeff, pop by my place - I have one for you...

    Right? It has also amazed my son and I as Z cars passed through our shop how different each one was to another. They all have different "personalities" - rather than: "a Z is a Z is a Z"... It's definitely a car you can make your own.

    Just posted this on HybridZ - not to double up, but I thought I'd add to what these brilliant Gentlemen are saying: Jeff, hate to keep harping on the transmission slave cylinder, clutch fork, collar, and throw-out bearing... BUT... I strongly recommend that you get the correct length collar and use the stock throw-out bearing. When all that is correct inside the bell housing, the fork should be pushed forward far enough that there is virtually no play between the fork and the stock slave push rod. In it's current configuration I believe you may well have trouble with the collar moving too far forward and slipping off the tube that it should glide back and forth on. If it does that while driving you'll be in trouble... The collar length needs to match the pressure plate thickness (not necessarily the type transmission you have but the clutch package). I have 3 different length collars in my collection. I also have fear and trepidation about that mustache bar. You definitely have an R180 diff and you need an R180 mustache bar that's mounted properly. The Z differential has a tendency to move - a lot - in it's factory fresh condition and I always want those bolt holes to fit nice and tight because the nuts will NOT hold the differential to the bar (without moving) by themselves. +1 on the starter relay - The start signal is one of the most common Z deficiencies. The solution many people use is to connect the start signal to a relay coil and use power straight from the battery to engage the starter solenoid.
