Still struggling with car at idle after 8 years
You'd better correct or explain this. Otherwise, the CZCC members will write you off for good. Specifically: No one (in their right mind) tries to rev their engine up to 6000 rpm at rest. Hot or cold.

KONI Sports for Classic Z's
After taking my Z off the road in early November 2024, I'm back to trying to get these Koni shocks properly fitted in my Series 1. If any member has any updates from their Koni fitting experience(s), please share. Thanks

79 280zx Fuel Damper
My Dad always preached to not put old parts you can afford to replace back on the car. Lots of exceptions to that statement but you all know what I'm saying.

Putting out the feelers
The front end look great! It could easily be changed by the new owner. I suspect if he couldn't figure that out he probably would not be interested in buying a really nice z car.

Darn Tire Jockeys
I've been using slotted hockey pucks as lift pads for several years. They work quite well. Just make sure that the slot is wide enough to keep the puck from wedging itself onto the pinch weld strip and deep enough so that the load is taken by the rocker and floor panel metal on either side of the pinch strip (rather than by the pinch strip itself).

Best Suspension Upgrade for a 280ZX That Keeps It Streetable?
Motorsport Auto | Z Store Has the complete set shock absorbers and springs. For 625 dollar. when you see costs for a "today modern car" this is VERY VERY SHEAP !! I don't get todays cars they are stupidly expensive and brake down all the time.. and just to change a bulb the whole bumper has to come of???!! Welcome to todays technology it's crazy!!! And then all those stupid gadgets,, what? a auto windscreenwiper?? I DECIDE WHEN TO WIPE .. stupid car.. auto lights? going into a little tunnel.. the light flicks ON, and stay on for about a minute. pure waist of energy.. i know.. but if a million cars do this it's a LOT of waisted energy.. Lights on all day.. stupid waist of energy.. are people blind these days.. lights on should be there for motorbikes only during the day.. just my opinion.

Hose Clamp Finishes
OK, I was so focused on the finish color I totally missed the fact that the screw was a hex-head instead of a pan-head JIS! D'oh! Captain, I really don't know the history of this car...so nothing surprises me. But here's my basic question...now that I have all the small hardware cleaned and ready to send out for plating, should all my hose clamps go in the "clear zinc" box or the "yellow zinc" box?

Saving car #34464
I got the SU Carburetors back from the doctor. When they were done in 8/2000, with updated throttle shaft bearings at that time, there were 2 holes inscribed "inject grease". I believe the grease I injected caused the seal to leak. With the idle screws turned all the way out, I couldn't get it to idle below 1000 rpms, and I couldn't balance them. Ztherapy got rid of those older style bearings, re-machined the bodies, and plugged the old grease holes. I actually have to turn down the idle screws now to keep it running, unlike before.
- Charging fun with Zedyone !

1970 Wiring Diagram
So @Mike , I tried to delete the old obsolete incorrect previous version of the wiring diagram (version 6.0 on page five of this thread), and the edit privileges will not allow me to do so. I'm assuming there is a time limit on how far back in time one can go to edit something? And that post on Feb 11 has exceeded that time limit? Can we change that? Or at least, can YOU delete it if you won't allow me to do so?

Duffy's 1/71 Series 1 240z build
I got my Datsun Z Car Series Oil Sending Unit Relocation / Remote Block done! I have only one for sale now, but more are on order. I am pretty proud of this design. Three outlet remote oil sending unit block. Metal 3D printed out of aluminum to look stock and mimics the 240z, 260z and 280z brake proportioning block design. Block has 3 outlets, all are 1/8 NPT. Comes with a custom length -3AN hose and one 1/8 NPT -3AN fitting and either a 1/8 BSPT or 1/8 NPT for the engine block side of the hose. Stock sending unit on a 240z is BSPT, this will require a NPT sending unit like this. [https://zcardepot.com/products/oil-pressure-gauge-sender-240z-260z-280z-70-77?variant=32184292737137](https://zcardepot.com/products/oil-pressure-gauge-sender-240z-260z-280z-70-77?variant=32184292737137) No sending units come with this order. Pictures of sending units are just for reference. Link: https://www.m2racing.com/shop/p/datsun-z-car-series-oil-sending-unit-relocation-remote-block

Impossible Oil Leak?
Well he is a mechanic and used to also race a camaro single carburetor car. He is 69 years old. Ill guess ill just wait for the new parts to arrive.

Size? Fuel Line Replacement
A possibility of fuel starvation. The end of the return of the fuel rail is restricted so there is some back pressure on the supply side to the carbs. If the lines were reversed that back pressure won't be there to feed the carbs.

Seat Return Spring
I did but to no avail. I even ended up blasting the old grease/dirt out with brake cleaner and then relubing it with sprayable silicone lubricant but the squeak didn't go away

[2025] What Did You Do To/with Your Z Today?
I hope you strapped them down to the headlight scoop for the drive, although I think you'll need to wait a while before opening them.

Check out this ATK crate L28 engine on BaT
Thanks, and that is interesting. Google Translate serves its purpose well. Is there a Japanese Wikipedia? Any thoughts on where that "new" N42 casting comes/came from? There is a disconnect between ATK Vege (which seems to be a combined company, looking at the logos and the descriptions) and the KSS that comes up through that Japanese ATK link. 1936 versus 2003. North America versus Japan. From the web pages - https://atkvege.com/about-atkvege/ About ATKVegeATK North America is the largest private label Crate Engine Remanufacturer in North America. Partnered with our sister company, VEGE de Mexico, ATK VEGE has a history of Remanufacturing that dates back to 1936. https://atk.co.jp/company/ name KSS Co., Ltd. Representative President and CEO Keiji Okawa Established August 2003 Capital 3 million yen

Well that's no fun!

How vibration free is your 70-71 240Z?
Since you're in experimentation mode and you have fabricating skills, you might remove the factory mount and fab up a new mount that gives the desired angle. It wouldn't need to be super strong or made for permanence if you're only evaluating cruising speed. Keep the strap in place in case of breakage. It could be a solid mount. If the angle is perfect but the vibration is the same, then you can start looking elsewhere. The RTz mount either gives a certain angle with the GM mount, or it gives a range of angles in use with the snubber, as the diff nose moves up and down. The GM version is an actual mount, the snubber version is essentially a solid strap. p.s. have you considered mounting a camera under the car to see what the diff nose is doing while driving? Maybe something is moving. Or, looking back at your pictures of the crossmembers, why don't you just shim the crossmember mount downward with some washers. Perfect the angle, take it for a drive. then you'll know if you should go further.

In the previous version (of this site) it was absolutely possible to change the title, but i think only in the first month or so..
