Hey all! I'm slowly working through the auto to five speed swap right now and am ready to route the hard line. I have a hard line from the parts car (1981 ZX) that I was planning on using but seeing how complicated the routing is, I want to make sure before I start that this will work. I'm totally fine buying a prebent line for the 77 if it doesn't. Has anyone done this successfully? Should I just bite the bullet and buy the line made for the car? Thanks in advance!

Hello all, I believe my oil pump is one or two teeth off due to the alignment of the distributor pin when #1 cylinder is at TDC. My question is whether or not it actually needs to be corrected. Can simply adjusting the orientation of the distributor correct this? My car is a 72 with SU carbs and I'm running a MSD unilite distributor on a Datsun Spirit 2.7 liter engine. It runs pretty well, but is difficult to start and seems to pull/ let off at light throttle while cruising. Thanks for any input. Cheers, Scot

Does anyone know the threading size for the differential drain and fill plugs. I tried to measure them and came up with 27x2.0 but apparently this was incorrect. My "Thread Detective" doesn't go this high.

I have an early 5 speed here (77-79 “B” type 5 speed) that I’m rebuilding that has a busted out tail shaft casting where the output driveshaft seal goes. Was apparently dropped at some point in it’s life, the dust shield is clearly bent and re-shaped by a PO. I’mm looking for brilliant and inventive ways to fix this (I mean cheap…..)

I'm restoring my dad's 1973 240z and since I'm doing the brake lines I might as well do the fuel and clutch lines. Here's my question. What is the difference between the 1972 fuel lines and the 1973 fuel lines. Buying a set it's a $200 difference, but when looking at clutch, return, and intake that adds up quick. The car has the round top carbs from 72. Can I run the 72' lines in the car or do I need to bite the bullet and get the lines for the 73? Car was manufactured in Sept. of 72.

As the title states, I finally was able to start my Z up and let it run/drive it for the first time after buying it (brakes didn't work and neither did the clutch hydraulics; The car was backed into the garage so I didn't want to inhale exhaust fumes trying to let it run.) Now that it can run, change gears, and stop, I'm met with my next line of issues: - Car idles high warm or cold (1,500 rpm.) If let sitting while idling, randomly it will start to fumble and die unless you give it gas, then it generally will return to its high idle. - When driving, it feels like its misfiring a bit. It will respond to throttle and rev, but seems down on power and you can …

The car: 1971 Datsun 240Z. Original motor, fresh rebuild (less than 2500 miles.) Original SU carbs freshly tuned, New spark plugs. MSD Hall Effect electronic ignition, Pertronics coil. Electric fans. Schneider Stage II cam and new springs. 6-2-1 headers with carb heat shields. 4 speed manual transmission. All smog components deleted. So, pardon the lengthy intro. Bought the car Jan of 2023. Fresh rebuild on the motor. Always smelled gas in the car, so after researching the forums, it seemed like fuel hoses were the place to start. Also I saw fuel dripping at the rear of the car. So I removed the fuel tank and all hoses and replaced said hoses because…

I'm getting back to installing an LSD in my R180 but I was concerned about the LSD heating up the differential during Auto-X. I drilled/tapped a hole in the fill plug for a temperature sensor but I also was looking into an alternate differential cover with extra volume and cooling fins. I located a family-run foundry operation that will do a one-off aluminum casting for $40 plus $3/pound so I designed one. Anyone want to comment on the design?

Almost got stranded yesterday with a starter failure. Was able to bang on it with a hammer and get another start of of it. I’d just get one “click” when I turned the key. This is a remanufactured (AC Delco -premium) gear reduction starter. I love when they put crap like “premium” in the description….lies lies lies! I bought it on Rock Auto 27 months ago and as expected the warranty expired 3 months ago. With a little I drove this car it might have 100 -200 starts on it. This is the world we live in where stuff appears to break right after the warranty period as if they know this when the rebuild. My Toyota (OEM Denso) starter on my 08’ 4Runner is the origi…

A while back, I heard that the original distributer cap was grey. Going off of that and a poor quality picture on BAT, I was able to find a grey YEC branded cap, but didn't know if it was close to the correct color. Today, I found a picture of an original Hitachi distributor cap: Putting that here for reference for others.

Does anyone know of a shop rebuilding 5 speeds in the PNW? Close to Portland is preferred, but am willing to drive if there's someone who has a ton of specific experience with Datsun stuff. Thanks in advance!
