In the process of planning direction of restoring 2 1971 240Z, I am looking at the wiring system of the cars. Although the wire harnesses appear to be in good shape, it seems that that originally there was a capicity issues (ie headlight relay upgrades etc.). The ISIS system is comparmentized, you have a main power block, which would then control the power to two additional power blocks such as one in the engine compartment and the one to handle the rear harness section. Personally, I think this would upgrade the car(s) significantly and make the electrical system more reliable? Appreciate everyone's thought of going this route! newtonhubcap

Had a stock 72 Z with 68k miles that I thoroughly enjoyed but moved on to other sport cars. Wanting to get back into the Z world that I miss, but unsure about a modified version. The car is the blue 71 with a 3.1 stroker (Rebello) advertised in the ad section by jackboxxx. Anyone familiar with the car? My conversations with the owner have been very positive and reassuring thus far, but with my limited technical knowledge on "built" motors and reliability (this one appears to be well-maintained and not excessively "massaged". i.e. no track/drag days), I want to get some input from the community. I do not intend to track the car myself, but do want the extra performance …

What would my best option be for my flow guide valve. Currently I have the tank line coming into it, the air cleaner line going to the back of the air cleaner box, and the crankcase tube just blocked off. Crankcase tube blocked because I have no nipple for it on this blocks vent outlet. My understanding is the 240 blocks have a smaller nipple coming off of the same vent that goes up to the pcv valve. Should I run the crankcase outlet up to the intake manifold? My thoughts on this is wouldnt this be pretty much exactly the same as running it to the crankcase vent that goes up to the manifold anyhow. Could I just scrap the flow guide valve and run the inlet from tank …

I rebuilt the clutch master and the operating cylinder. The master won't pump fluid thru, but if I take off the connecting rod and push the pump with a screwdriver it pumps, with the connecting rod in place, nothing? Weird, got me puzzled, any clues?

In the service manual it instructs to use a "conductive sealant" when installing the oil pressure switch. Nissan dealer says they use teflon tape. I don't believe that is conductive. Any advice? Second, after running for a while going into town and restarting it misses badly until I take off and then it hits smoothly on all six. It used to do it only after a an hour or so on the freeways. Now it does it on a trip to town. It has me baffled. Any suggestions would be appreciated. Rod

I have my differential cover off and both of my rear brake drums. I am getting ready to take all of my suspension parts to be powder coated. I am wondering what is best for the aluminum pieces - differential and drums. Is it ok to sand blast these parts or is the aluminum too soft. What is the best way to clean the aluminum to get it looking shiny and new. If I can get it shiny and new I can either leave looking this way and clear coat them. What is the best cleat coat for these parts. The drums probably need something that can handle the heat. If the aluminum is too hard to get shiny and new looking, would you just powder coat them in silver or whatever other color…

I have been on this forum now for acouple of month but have not properly introduced my self. First and foremost thank you to all the guys and gals on here that have been kind enough to share their wealth of knowledge on our Awesome Z's.

Inside is actually pretty good black vinyl, It doesn't ahve a radiobut everythign is immaculate in terms of actually being THERE. So I was fortunate to work at a Dealership that got it in for a trade and i jumped right on it. Anyway I am from Ardmore, OK. and Have loved always to work on vehicles and this will be my official resto…

I thought I took a lot of pictures when I disassembled my '72 240Z four years ago, but I didn't take enough! Can you identify these brackets. That's a foot long ruler at the bottom of the picture. Pretty sure they are on the bottom of the car someplace. Thanks.
