Finally got one...now to make it mine: 1973 240z Refresh / Personalisation
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.

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.

When and Where did You get yours?
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.

Mechanical Fuel Pump Woes
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.

Mechanical Fuel Pump Woes
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:

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?

I do now believe it is vapor lock due to the elevation and recent temps in the high seventies. I triple wrapped my factory fuel rail with Thermo-Tec this morning and switched spark plugs to match my E12-80 dizzy. My recent plugs were a perfect brown shade. I was very happy with their appearance. I decided to take her up Pikes Peak last week. What a blast. The 15,000+ foot summit was closed due to weather, but I made it up to around 13,500 feet. I hope you enjoy the photos. I am very excited to be getting a baseline dyno tune for my engine this week. $80 for three runs. My plan is go with run 1 as-is. On run 2 I'd like to crank up the timing and see the results. And following that I'm considering turning the mixture nuts an extra 1/2 to 1 full turn richer for the 3rd run to see if she wants more fuel. Thoughts?- Finally got one...now to make it mine: 1973 240z Refresh / Personalisation
I've been chasing a fuel starvation problem both at starting and WOT. I suspect it's vapor lock a result of 80 degree temps at altitude. It's time to put some heat resistant tape back on the fuel rail.- Finally got one...now to make it mine: 1973 240z Refresh / Personalisation
They pop up fairly frequently. Not a big following here. Most bodies are very clean or very ratty, one or the other.- Finally got one...now to make it mine: 1973 240z Refresh / Personalisation
Some updates: - I have another failing mechanical fuel pump. $16 cast unit from Amazon. - I picked up a two owner early 260z from NM to resell (yellow). She was purring like a kitten within an hour of getting home. - I stumbled upon a "rust free" 72 two owner California car (white). Cleanest underside I've ever seen. My 73 may go back to stock and be sold in order to keep this one.- 1972 Datsun 240z Clean Title
Sorry gents, the car has been sold. Off to France.- Finally got one...now to make it mine: 1973 240z Refresh / Personalisation
A dead fuel pump left me stranded one day. Surprisingly I was able to limp home. With 2 day shipping from Amazon, she's back on the road.- Finally got one...now to make it mine: 1973 240z Refresh / Personalisation

I've put a few hundred miles on her in this gorgeous Colorado winter. The clutch is really soft, and I have a huge to-do list, but every 30 minute drive is glorious. I will have to do the clutch before any autocross or drag racing. Coming soon: ZStory twin tip muffler Fully rebuilt NISMO (Datsun Comp) Mikuni 44s Facet fuel pump- 1972 Datsun 240z Clean Title
I do have a timing light. Time is the factor. I don't know who rebuilt the engine. The body is not cut for flares. Yes, sorry, no carpet. Just some floor mats. No rear bumper. The image is a vinyl decal with the Datsun emblem. Car is currently listed on eBay. I'm going to install a fresh reman dizzy and see if it gets rid of the sputter.- 1972 Datsun 240z Clean Title
Update: clean title in hand. Price is now best offer. Will be listed on ebay at the end of this month.- All you can carry for 59.99

Long overdue update. The rear suspension renew and overhaul was a success. Everything was sandblasted and painted with VHT Roll Bar and Chassis paint. Tokico Illuminas and Vogtland springs (I wanted to give them a try). 4:11 open R180--I love it. The five speed is very nice as well...I need to stop forgetting that I have that 5th gear! I will post more photos from my phone. Funny story. As soon as the rear was buttoned up I went on three joy rides with 18 month old gas. All of a sudden, she wouldn't run. I suspect I got water in the distributor at the car wash. She was down for a few weeks. I went through 10 reman Cardone dizzies before I got a good one. I decided to upgrade to the 280zx distributor while I was replacing it anyway. 10! Now, I've logged another 40 miles or so. She's a blast. I refinished (amateur) a set of Watanabe RS-8s and these will most likely never come off of the car. She will be parked again for a clutch master cylinder (does anyone have a source for a larger bore?) and the clutch slave. Engagement is very weak, even after bleeding. After the clutch parts, next will be a retrospec front air dam and a 432 rear spoiler. - Finally got one...now to make it mine: 1973 240z Refresh / Personalisation
