I defend myself against unwarranted attacks - texasz came on here on the 26th and by the 29th all had been sorted however during that time you and another attempted to dissuade my client from buying from me ! Yes, I'm not the strongest at IT - each to their own, can you make exhausts ?....... and it was my IT guy that mumbled something about windows and logons - what do I know.... As for my customer base - texasz wasn't yet a customer so how would he be in my customer base. It's sorted for texasz so let's move on, please - have a great day.

ITS ALIVE. i decided to take off every electrical connection off and deep clean each pin. they didnt have bad corrosion but the copper had turned green where it wasnt connected for the last 20 years. I double checked each pin ohms coming through the ECU and finally got each reading within spec. Started it up and boom perfect idle. I appreciate all you're guys help. the resources and information helped a ton. now to bleed the clutch, find out why the break pedel is stuck and see if this thing can move!

You are right! Mechanic should get this engine running with pertronix ignitor module 1761, 1.5 coil and 1.5 ohm ballast.

I love the 510. Never owned one but…

Photos are of the original N33 exhaust manifold I removed from my 73. Replaced it with an earlier one when I went to round top carbs. I confirm you need a different downpipe. I was able to swap my 73 downpipe for an earlier one.

http://www.zcarblog.com/wp-content/uploads/2025/08/July-2023-First-Drive-on-KWs-e1757565270666.jpg This is Matthew’s 1973 Datsun 240Z featuring our Z Car Garage KW Suspension. He has kept the car mostly original aside from chassis and drivetrain upgrades including a triple-carb’d L-Series, Watanabe wheels and Recaro seats. Let’s take a look at how Matthew got into Z cars… http://www.zcarblog.com/wp-content/uploads/2025/08/July-2024-Paint-Correction-2-e1757565546687.jpg Matt is from Calgary, AB and we know him through his father, Rob from many years ago. Our good friend Herbert was selling his original paint, 87k-mile 240Z and Rob noticed it on zcarblog.com leading to his acquisition. MATT: My Z car story is a family affair that began at a young age. Growing up, my parents both owned Z32 300ZX convertibles — which, incidentally, is how our connection with Z Car Garage began in 2004 when Rob and the team at Z Car Garage did a pre-purchase inspection on one of the Z32 Convertibles before being imported to Canada. We were active in a local Z car club in Calgary, Alberta, attending events with the 300ZX. At the time, the 350Z was new and exciting, and I even had a poster of one on my bedroom wall. http://www.zcarblog.com/wp-content/uploads/2017/01/phan-112117-018-e1485412969426-1024x631.jpg http://www.zcarblog.com/wp-content/uploads/2021/01/PXL_20201221_020624527-e1611120295487.jpghttp://www.zcarblog.com/wp-content/uploads/2025/08/October-2020-Driving.jpg But to truly understand our story, it’s important to go back even further. When my dad was a teenager working at a local gas station, he fell in love with an orange 240Z with a white interior that often came through. He was 18 at the time and never forgot that car. Fast forward to 2009, when Rob from Z Car Garage called and told my dad he had to buy a 1973 240Z that had just been featured on ZcarBlog. My Dad flew down to Seattle, WA to pick up the car and drove it back to Calgary, AB. I was 15 then, and I vividly remember working on the car with my dad. We replaced the dash with an original, uncracked one, fixed a minor oil pack leak, and made lasting memories at local car shows and events. http://www.zcarblog.com/wp-content/uploads/2025/08/August-2011-18th-Birthday.jpg When I turned 18, my dad gifted me half-ownership of the Z. Unexpected circumstances forced us to sell the car in early 2012. By then, though, I had fully caught the Z car bug. I spent the next year or so searching high and low across classified ads in the U.S. and Canada, but nothing quite compared to our Z. On a whim, I posted a “wanted” ad on our local classifieds, using the most recent photo I had of the car. Then, in March 2014, I received a message that simply said: “Hello, I own your old car,”…followed by a phone number. We exchanged a few emails and calls, and they even sent me a photo of the car’s current condition (below, March 2014). http://www.zcarblog.com/wp-content/uploads/2025/08/240Z-March-2014.jpg On April 5, 2014, I picked up the car and drove it straight to my dad’s house. He didn’t know I had bought it back. I drove past the house, and he spotted it from inside. I don’t think I had even parked before he was out the door, beaming with excitement. Not only had I gotten back into a 240Z — I had brought home our 240Z, the same one we had built memories with years earlier. http://www.zcarblog.com/wp-content/uploads/2025/08/June-2014-After-Purchasing-Back.jpg From 2014 onward, the car remained largely untouched. Matt was finishing university and starting his career, and while he drove it when weather permitted, the Z mostly stayed as it was. Behind the scenes, he was always dreaming of how he’d eventually build it — period-correct modifications, all reversible, in case they ever wanted to return the car to stock. http://www.zcarblog.com/wp-content/uploads/2025/08/August-2020-NissanDatsun.jpg In 2021, he began collecting parts for the build. He started with a second set of suspension components, which allowed him to send the spindles and hubs out for the KW coilover conversion and have other parts powder-coated or zinc-plated.

A few years later, I reached out to KW and learned that Z Car Garage would be the exclusive dealer for the kit. Given my family’s long-standing history with Z Car Garage, it was an easy decision to contact Rob and place an order. http://www.zcarblog.com/wp-content/uploads/2025/08/July-2024-KW-Endless.jpg The installation was straightforward, though slightly more involved than on a modern car due to the need to install bearings into the hubs. I also opted for the KW adjustable top hats, as I planned to run 16×8 +0 Watanabe wheels and wanted to avoid rolling the fenders in order to preserve the car’s originality. The first drive revealed a night-and-day difference compared to the stock suspension—firm, yet compliant enough to maintain comfort for street driving. Although Z Car Garage ships the KWs with a recommended out-of-the-box setup, we ended up softening the settings slightly to better suit the rougher roads in Calgary, Alberta, which are no match for the smoother roads in California. http://www.zcarblog.com/wp-content/uploads/2025/08/KW-First-Install.jpg http://www.zcarblog.com/wp-content/uploads/2025/08/Rear-Underside-1.jpg In the corners, the car feels extremely planted, with excellent turn-in and feedback. With my current setup, the grip provided by the suspension and tires far exceeds the car’s power output, making it an absolute joy to drive and toss around in corners. Before installing the KWs, I drove more conservatively, hesitant to push the car too hard. Now, with the upgraded suspension, my confidence—especially in corners and at higher speeds—has grown significantly, allowing me to truly enjoy the full potential of my Z car. http://www.zcarblog.com/wp-content/uploads/2025/08/240Z-May-2025-1.jpg It took a couple of years to gather everything, but with the help of a good friend — who also happens to own the local performance shop, VEX Performance in Calgary — the build finally started coming together in July 2023. We removed the old suspension and replaced it with freshly powder-coated components and, of course, the KW suspension. The engine bay was cleaned and prepped for the new Fujitsubo exhaust and triple Weber setup. http://www.zcarblog.com/wp-content/uploads/2025/09/IMG_6118.jpghttp://www.zcarblog.com/wp-content/uploads/2025/09/IMG_6101.jpg http://www.zcarblog.com/wp-content/uploads/2025/08/240Z-R34-GTR-e1757565636237.jpg But the moment it all came together was when the car was lowered onto the ground, sitting on its new Watanabe wheels. That’s when it hit me — a rush of emotion. The same Z my dad bought in 2009, the one I brought home in 2014, had finally become the car I’d dreamed of for years. http://www.zcarblog.com/wp-content/uploads/2025/08/240Z-May-2025-2-e1757565521969.jpg Thanks for your support Matt! We love that you are building and enjoying your dream Z car! What’s next? MATT: As of 2025, the Z is exactly how I envisioned it. I take it to local Cars and Coffee events, car shows, and the occasional late-night meet. As for future plans — they’re still up in the air. I’ve considered going EFI, or maybe even an OS Giken TC24 build someday. But for now, I plan to Enjoy the Ride. http://www.zcarblog.com/wp-content/uploads/2025/08/August-2023-Passenger-Priness.jpg Build Sheet: Engine/Drivetrain Triple Weber DCOE40 Kameari Exhaust Sheild ITG Air Filter w/ Carbon Backing Plate Fujitsubo Super Ex Header Fujitsubo Legalis R Exhaust Koyo Radiator Malpassi FP Regulator Nismo Fuel Pump STI R180 3.54 LSD http://www.zcarblog.com/wp-content/uploads/2025/08/August-2023-Car-Show-Debut.jpg Suspension KW V3 Coilovers w/ Camber Plates Endless Front BBK T3 Rear Control Arms T3 Front Tension Rods ST F/R Swaybars 280ZX Rear Disc Brake Conversion SuperPro Bushing Kit Wheels/Tires Watanabe R Type 16×8 ET 0 Watanabe Electron Lock Nuts Continental ExtremeContact 225/50R16 Interior Recaro Classic LX http://www.zcarblog.com/wp-content/uploads/2025/08/Septemeber-2023-Local-Zs--e1757565477500.jpg View the full article

Hi Site Been a while….not sure, but whatever adds .080 inches….if they are .040 inches, 2 would do. Don’t hesitate to call Eiji….tell him you’re my cousin and if wants to keep eating steak at our house, he needs to be nice! 🤪 He’ll sell you the right stuff.

Ok thanks but would you know the casting number on the OEM exhaust manifold please ?

I believe he mentioned 10 plus years.

I've been stuck on this album for a couple of weeks now. I'll put on something else and after that finishes I'll say to myself... Let's give John Hiatt - Walk On another play.

I do, I ordered another from Nissan to replace mine. When I get back in town from Boston, I’ll post the p/n. Can’t remember if it was superseded.

I live in arizona... i bought it and it just arived in less than 24 hrs. fastest turn around for a relay i thought i would have to wait 1-2 months for.

Im in good company!!

Thanks Matthew for a great write-up =) Here is my tiny contribution to it: You were wondering about the Thermal switch 22110-E8000 and stating that it's probably for the automatic model only. I found information which connects it also with the manual model, with the emission control device (EGR) to be more precise. It can also be found from the -73 wiring diagrams (both manual/auto). Please see pictures below: Keep up the good work!

They look better wet.😁 Mine has water allergies though. Now for some windshield time.

It's a EX-mouse.. 🤣

Thanks for the mention! I just updated the thread as I’m diving head first into the AFM rabbit hole. Some tips I picked up on my journey: - Clean all the electrical connectors to the sensors (also the bullet connectors in the harness). - Measure the resistance to the AFM air temperature sensor and the coolant temperature sensor to make sure there within spec (coolant sensor is one of the most important sensors in the EFI system!). - Buy or borrow a timing gun and make sure the timing is set correctly. - Verify you are getting enough spark (right type and gap spark plugs, distributer contacts in good condition, ignition coil resistance within spec (0,8 to 1 Ohm)). - Install a wideband O2 sensor with gauge (cheap Chinese one is good enough for now) or if you don’t have a bung in you exhaust buy an exhaust sniffer so you can measure you AFR (Air Fuel Ratio). Idle should be around 14,7 and wide open throttle 12,5 I believe. - Try and see (while monitoring the AFR) if only you idle or the entire rpm range is out of spec. If it’s only idle maybe try and play with the idle air screw on the AFM to get the idle AFR back into spec. And If nothing work only then take the AFM off the car and start testing the resistance values. The number 7 pin is hard to measure the resistance so you must hook it up to a battery (9 or 12V) to test the output voltage on the number 7 pin. If you determine that that is your issue then welcome to my world! As you are based in the US maybe an AFM rebuilt offered by jdm-car-parts or Z-store is an option for you. Unfortunately I am not so it would cost an fortune to do so for me in postage and import tariffs.
