  1. By luck I stumbled on a 1971 #18720 Series 1 car that will become my new project. I will use this thread for any further updates on the 1973's sale.
  2. Tragic news. 11/2019: I was entering my neighborhood, slowing down from 45mph and turning left. I cut my wheel 90 degrees directly on top of a 2 inch pile of sand and skidded into a guardrail at 10-15mph. I will be pulling my motor and drivetrain and selling this poor 240z on ebay within a month or two. She is definitely repairable but beyond my abilities.
  3. Jason240z, it's the previous version, I bought this less than a month before the new style was released.
  4. I just finished my taxes, so it's time for an update! I'm absolutely LOVING the Mikuni 44s! I need to schedule some dyno tuning this summer with Jeff Winter. Here's a video clip from the SU dyno runs I mentioned before. Sadly, they wouldn't let me touch the engine bay between runs. IIRC the numbers were right around 140whp/tq at 6000 feet.
  5. Yesterday I took a 14 hour round trip drive through the San Juan national forest to pick up this 73. Fairly solid but has some frame rail rust.
  6. I still need to sort out linkage, fuel rail, and initial jetting.
  7. Slow and steady. I chose to get the valve cover powdercoated gloss black.
  8. It's the older version. The resonator sits a couple inches lower than the floor boards. Shouldn't be a problem unless the car is slammed. I just have some Vogtland springs and Illuminas.
  9. I ended up selling my completely rebuilt (by Eiji at Datsun Spirit) "NISMO" 44s also known as the Type 4. I instantly regretted it, and two weeks later bought these Type 3 Datsun Competition versions.
  10. It's been a while. Fujitsubo is a work of art. I can't wait to hear the whole twin pipe system. A freshly vapor blasted JDM valve cover will be hydro dipped in black carbon fiber.
  11. After much disappointment, for an unknown reason, the ZStory header/exhaust did not fit my car so I returned it for a refund. There was no clearance at the trans crossmember and a header primary was touching my steering rod. There is much debate about this on Facebook group DPAN, whether my car is bent, the welder made a mistake, etc. I got a refund and will be installing the Fujitsubo system soon. So far everything fits like a glove, plenty of space around the header. I'll upload photos when the install is finished.
  12. Updates: Installed Retro spec type 1 air dam Installed early 240z front bumper ------------------------------------------------------------------------------------------------------------------ To do: Install Z Story header/exhaust NISMO Mikuni 44 swap (Harada intake kit, Kameari fuel rail)
  13. I've disconnected the hoses from the carbs plenty of times. Not even a trickle.
  14. 2011 was the end of my starter marriage. Time for a new toy! [I also bought a 2008 Z51 C6] I searched craigslist for a Z within a 300 mile radius of Augusta, GA for months. I finally found one, 1973, decent looking in the photos, for $4000. It was a 2.5 hour drive up to Greenville, SC. The PO bought the car from a Datsun dealer in 1976. He said it was the longest relationship of his life. Daily driven in the 70s and 80s, locked in storage for the following two decades. He said, "I tried to sell her once before, and the guy showed up, but I had to send him away." He handed me the keys and told me to take her for a spin. The rings were sticking from sitting so long so she was blowing plumes of smoke. We took it to a nearby shop for a compression check; steady across the board. I was ready to hand him $4k on the spot. He decided to offer a $500 military discount AND delivered the Z 2.5 hours south back to Georgia. Every so often I think about selling her, but I've owned her for 6 years and have only logged a little over 2,000 miles. I still have some bugs to work out but I want to drive this Z for a long time. The paint job is a 10-footer. I intend to keep it that way. More of a driver's car.
  15. I've replaced all fuel hoses in the engine bay within the past year, most within the past few months. I didn't think of the vacuum pump Steve. Are you saying connect it between the pump and the oem fuel filter? I can't help but think if my fuel system is sucking air somewhere, it must also be leaking fuel somewhere? I did find a slight crack/drip of a fuel line about a month ago and replaced it immediately. I thought it was the culprit, allowing the filter to slowly drain, but I'm back where I started.
  16. Alrighty. I've replaced three mechanical fuel pumps in my 73 240z in the past five months. [Because I initially thought this was the root of all of my problems] It seems as though the pump loses it's prime every time she sits for a week or two. For example, today: oem-spec fuel filter is clean and new. The filter is full of gas. Car will not start with a solid 2 minutes of cranking. No fuel is making it to carbs. What gives? It's like the pump is sitting there doing nothing. I can blow gas through and suck gas in from the supply line easily. Gas tank is fairly clean--fuel filters have never been dirty in the past 6 years of ownership. SU floats have been set 3 times, mixture nuts 2.5 turns down. Losing my mind here! My two next steps: Remove valve cover to inspect eccentric gear and activate pump by hand. Remove OEM fuel rail and check for debris (is this even a likely culprit?). I am already planning an electric fuel pump install because I'm so tired of this. Here are the threads I looked into:
  17. My only work to be done before the dyno session is to replace some heater hose bypass caps that are starting to show their age. Unless you folks have any other recommendations? WORK TO BE DONE IN THE NEXT COUPLE MONTHS: Install retro-spec type 1 air dam Install Les' 432 rear spoiler Rebuild/refinish NISMO 44s Electric fuel pump install Seats?
