Welcome to my Blog devoted to the restoration of my 1972 Datsun 240z. I purchased it in 2013 and have been actively working on my driving-restoration, so I can enjoy the car rather than having it in pieces for years. Please enjoy the write-ups below, as well as the how-to's. Feel free to reach out to me directly if you have any comments or questions. Thanks. - Dave
For all those with the original style paper/cardboard glove box insert in their 240z, I found a cheap and easy way to upgrade to a plastic insert from a later 280z.
Here is the picture of what I started with. A huge cut in the back of my cardboard insert from the prior owner. Its only gotten bigger since I've owned the car
Old and new side by side. The 280z plastic insert will need to be trimmed to fit.
There are various approaches, I chose to trim just the bottom tab and the made a new hole for the glove box door arm
The finished product is much nicer than what I had in there originally. I did need to mount the glove box door first and then slide the new insert in. I also put screws into these front holes to hold it better. I probably could have trimmed down the side tabs as well and use the original holes, but this seemed like a much more secure way of mounting the insert.
Finally purchased a nice set of wheels & tires. I chose to go with 16" x 7" Konig Rewind wheels with 205/55R16 Cooper tires on them. Very nice combination to fill the wheel wells and not rub with my 1" suspension drop.
Last night I replaced the choke (cold start) cables for the carburetors. They need to slide freely and after 44 years of usage and most likely never being lubricated since new, it was time. After doing some research I found that 0.055" Piano wire is the best option for replacement as its affordable and able to push and pull, which is required.
After disconnecting the cables from the carbs and pulling the center console apart, I removed the cables from inside the cabin, then measured the length needed. I left myself an extra foot before I cut the Piano wire. I bent it around the mounting plate and then lubed it very very very good before fishing it back into the housing and reconnecting. I'm very pleased with the results!
After owning the 240z for several years, I [finally] upgraded the fuel model needles from the M58 smogger needles to the original N27 needles. At the same time I purchased a set of K&N filters and mini-velocity stacks. The car does pull harder now when I accelerate and overall I'm happy with the results.
I did need to re-route my valve cover breather to a mini filter that hangs down below, and I also added a barb to connect the breather for the fuel vapor line. The SU Carb breather hoses are still connected and are positioned "down" in case the floats ever get stuck.
Fully disassembled, inspected, and rebuilt to factory specifications set of early Datsun 240z 4-screw Hitachi SU Carburetors, E88 intake manifold, balance tube, heat shield, springs, linkage, linkage to the firewall and air filter housing with OEM Nissan air cleaner/filter. As an option, you may choose the customer K&N filter setup instead of the OEM orange filter setup, or have both for an additional $50. Domes and pistons are polished and bodies have been painted with high-temp fuel-resistant paint and baked to cure. Also included is a Vacuum gauge installed on the balance tube to help diagnose engine problems and tune the carburetors
This is a perfect kit for the 260z and 280z owners who want to upgrade to the reliable and high performance round-top carbs. Ready to bolt on and begin using!
Professional installation is recommended as fine tuning may be required depending on the condition of your engine, gasoline used, and other variables not related to the carburetors. As with anything that is 43+ years old, these are not perfect but are great performers.
This set is being sold as-is for $700 (reduced from $850 asking price), shipped anywhere in the USA. PayPal friendly and ready to ship within 1 business day of payment.

Carbs were fully disassembled, cleaned, inspected, and rebuilt using Z-Therapy rebuild kit (ZT-150: gaskets, float valves, ZT nozzles, needles, gas hoses, etc). Emissions gear on the intake manifold has been removed and capped off.
Following assembly, I did run these carbs on my car to ensure they perform well and were properly tuned
