Hello! When I test my AFM air temp sensor, it comes back at 170 ohms, which is way too low. I looked through my spare parts and I found an old AFM with part number A31-622 420 Would this AFM work in my 78?

Hi guys, My distributor cap's center connector rubber bit seems to be melting courtesy of the HT wire from my spark coil. Is this commonplace, or is there something going wrong here? The car runs perfectly fine and only noticed this by chance...

Hi guys, Not sure if any of you have tried installing the MSA bullet mirrors (https://www.thezstore.com/page/TZS/PROD/classic02e02/50-1178) but I'm having a bit of trouble here. They mount by way of 2 bolts with their hex head facing the inside of the door (basically the mirror is installed such that the bolt sandwiches the door between the mirror's threads and the hex head of the bolt which is located under the curvature of the top of the door. This seems incredibly difficult to install as you are basically holding the hex head inside the door and hoping you can find the threads of the mirror blindly so I'm figuring I must be doing something wrong. Anyone…

Hi gang, Installing a new fuel sending unit (top loader for a '78 280z) but don't remember which direction the arm is supposed to face once installed (towards the front of the car/rear/left or right side). I keep bumping the internal bits of the tank during installation and once almost ran out of gas because the arm must have been jammed up against something in the tank denoting a full tank on the gas gauge. Any idea which way the arm is supposed to face once installed in the tank for a '78? -chase

I am in the middle of a special project on a 75 280z, part of which is a new vintage dash with retrofitting a set of Speedhut gauges. I need to find out the type and thread size of the temperature gauge sender port on the thermostat housing. The adapter in the kit is NPT thread, diameter is close but just slightly too big. Does anyone know is the port is metric or BPT? The oil sender is BPT and I re-tapped it for NPT for the new sender, it was only 1 thread off, 27 vs 28. This is the only adapter Speedhut has that appears to be close... Any ideas or insight most welcome...

I have a 71 240Z that I have owned since 1990. 3.90 R200. Engine is F54 blk , flat top pistons, N42 head. Supposed to be around 10.5 cr, head studs and Schnieder 260-70f cam. Have good set of SUs, but figure I need more air to run this baby. Don't really want the headaches of triple webers as I don't like tuning all the time, don't know about 390 Holley either. Just want a reliable setup to play a little with , but be able to take on 1000 mile cruise if desired. I'm looking for suggestions, Anyone running a similar setup and engine. Reliability is number 1. Am considering an efi setup, which one ? Got my first Z, a 76 280 in 1980, My track car is an 86 300zx wit…

Rear Spindle Pin 1 2 3

I know there are many threads on this topic, but I need your advice. i couldn’t get the spindle lock pin out so I took it to a local machine shop. I said he could take out the spindle pin too. He removed the lock pin but stripped one end of the pin. He said he heated the entire area to almost glowing red, but the spindle pin wouldn’t budge. Advice please: he wants to now cut thru the spindle pin between the gaps where the strut joins the link. He’ll then remove the strut assembly and then focus on removing the remainder of the pin from the link. thoughts?

I know this is a long shot, but I am looking for recommendations for a shop to rewire my 260z datsun. The guy who previously owned it did some wire splicing and other shady stuff. I figured that it's better to just get the whole thing rewired with a better fuse block and just get rid of all the gremlins I've been facing. no turn signals dead gauges and some other tings. I was wondering if anyone in the Pittsburgh PA area knows of any god shops besides what good old google recommends. Any help would greatly be appreciated. I just do not have the time ore space to do it my self. Thank you in advance.

Hi all, I've been searching high and low through all types of sites and groups trying to locate one of these A/C drier brackets as seen in the bottom right of this picture. Hoping I'll get lucky and one of you has one laying around I could buy. Thanks in advance!

Alrighty, Ive got a stock 1978 280z and I'm currently installing an MSD 6A and Blaster 2 coil into the car. After reading any and all forum posts on the topic I came to the conclusion that I would need an MSD Tach Adapter 8920 in order for the MSD box to Communicate to the EFI by upping it to 12v. All my wires are in place and I'm getting a good strong spark. I put a voltmeter on the purple wire coming out of the MSD tach adapter and I'm getting 12v. Only problem is that I'm getting no fuel. It must not be communicating with the EFI somehow. Here's my Setup. MSD 6A: Heavy Red goes to battery + Heavy Black is going to battery - Red is going to Bl…

I've finally got my 1978 280z idling decently... Kind of. It's been really touch and go. My distributor has been doing this weird thing where it starts making a grinding noise and then stalls the engine. Doesn't do it 100% of the time, but when it does, it's typically when I rev the engine or attempt to put the car into gear. This is leading me to believe that it has something to do with the oil pump or spindle rod or something. I've attached some photos of my old distributor cap and rotor and you can see where there's been interference between the rotor and cap. I have since replaced the cap, but continue to experience the same issues. Any thoughts? Anyone seen this befo…

Im losing my mind. I took pretty good notes for every fastener I removed from my 240 when I took it apart...except for these washers. Any thoughts where they go? I even ended up buying new ones from Nissan which are shown in the pictures.
