Unpacked my ZTherapy carbs in 2017 and bolted them up directly. Didn't touch them then and haven't touched them since. I have run ethanol free gas ever since I had the carbs done and with the "new" carbs I had to do the entire fuel system front to back at the same time.

But wait, I did this conversion back in 2017 and documented here;

And which one of these 3 almost duplicate threads are you going to stick to??

Just plug this into your Google search bar and add what you want to search for after a space at the end; site classiczcars.com I find I get better results with this search than the forum search box.

@Patcon When I went LED bulbs for all my exterior bulbs I matched the bulb color to the lens covers. From what I've read the lens will filter all colors from the white LED's except for the color of the lens causing the light to be dimmer than it could be. Don't know if this is an old wives tale, but just sayin.

As my sig says 12/70 build date, you can check Carl Beck's site registry for my vin if you want it.

Here's a shot of the passenger seat with the "L" bracket installed on the receiver belt. As you can see I did use the plastic sleeve to keep the receiver from falling to the floor.

I went through my receipts and found that I did order the hardware kit 9 days after I ordered the Roadster seat belts. I had to use the "L" bracket to fasten the seatbelt receiver part of the Roadster belt set to the floor next to the tunnel on my 204Z. Sorry that my answer is "oh contrare" to the other replies.

Like me, many 240Z owners have installed the "Dave Irwin" plug and play relay setup for the headlights. They should have documented it if they did this to the car. If done per the instructions it is completely reversable to stock.

ZTherapy replaces the bushings with roller bearings. Including me I'm sure there's plenty of folks around here that are very happy with our roller bearing carbs. I'd guess you'll be happy with your bearing mod.

I think they forgot to drop in the small block! 😉

Looks like a nice new Vintage dash!

Here's where the FSM is for a '73 240Z on this site. You've got some reading to do. And hey, there's lots of pictures of the parts talked about in the different sections.

Drop this thread and move to your new thread regarding dizzy and firing order.

As @240dkw says. Ignore where you think it should be. Once TDC is achieved per the cam lobes and cyl #1 all the way up the rotor in the distributor will be pointing at #1, then the firing order goes counter clockwise from there in the order stated in post #2.

Now that you have spark, things can move on. I remember in the other thread the topic of TDC came up and there was a response about where the cam lobes are and you might have been a rotation of on TDC. Open the Oil cap and see if the 2 front lobes on the cam are up in like rabbit ears. This should also be with the #1 cylinder all the way up like you described in the other thread with the screw driver in the spark plug hole. Your firing order is 1 5 3 6 2 4. With the engine at TDC as described the rotor in the distributor would be pointing at cylinder #1.

Here's the calculator I used when I changed to 15x7 wheels. Tire Size Calculator | Tire Size Chart | Tire Size Conversion | Discount Tire Ended up with 205/60 R15 which calculated out to be almost identical to stock tire height (assuming 195/70-14) so when my speedo reads 65 MPH actual would be 64.8 MPH, pretty close. The 205 is tire width and 60 is a tire height percent of tire width and the R15 is the wheel diameter.

I think he's referring to the stock fuel rail for the S U's where at the end of the rail where the return connects to the flexible fuel return line the end of the fuel rail is tapered down to restrict outflow to slightly pressurize the fuel rail.

Rather than the high pressure pump why not go with a low pressure pump. I did this one back in 2017 and it's working fine with my SU's. Motorsport Auto - The Z Store - K&N Electric Fuel Pump for Carbureted Z/ZX It's not the quietest but once the car is started I can't hear it over the exhaust and my exhaust isn't that loud. I use a magnaflow 10426 resonator with a magnaflow 13216 muffler, ceramic coated 6 to 1 header w/2.5" pipe all the way back. SU reliability issues... All I can say is bunk.

Mine are Gunmetal w/polished lip. It is hard to tell which is which...

I worked in IT for 38 years on IBM mainframes. Started on a 360 model 50 in 1971 as an operator and then as a MVT -> MVS -> z/OS sysprog. I'm very familiar with why you ran Lotus Smartsuite and what went down between IBM and Microsoft around the OS/2 PC operating system. Best WYSIWYG word processor I ever used was Ami Pro (acquired by Lotus and turned into Lotus Word Pro) before my company standardized on Microsoft Office.

@jayhawk Some poster humor. I loaded up the .odt in Word (MS365 so it's current). Did you know that Word only supports up to 17"X22" max page size, then it doesn't have "Export Directly as a PDF", word only supports PDF's in 8.5"X11". I loaded up LibreOffice Writer and your 18"X24" (which is a standard poster size) worked just fine and the same sized Exported PDF. So if anybody else wants to look at this you really should use LibreOffice Writer (it's free), not Microsoft Word. I did make some minor changes, hope you don't mind, here's what I did... 2023 THE LEGENDARY DATSUN 240Z CONCOURS INFO POSTER 18x24 a.odt

Thank You!

@jayhawkI really like your Z "An Instant Classic" history poster! Would you mind if I used it?

A funny cup holder story... Of course my wife's 50 Chev pickup doesn't have cup holders (we did get some recently that clip into the speaker grills in the dash). She got an award at the show and my wife had our 5 or 6 year old granddaughter in the truck with her while they were waiting in the award lineup. When they got to the front of the line my wife handed our granddaughter her water cup and asked her to hold it while she accepted the award. While the granddaughter was holding my wife's cup she said... "Grandma, you need to sell this truck and get one with cup holders".
