Crazy question. In a 4 or 5 speed trans, there is a plastic gear on the output shaft that drives the speedo cog. I need to know the number of teeth on that shaft gear. I've had several trannies apart in the past and recycled more of these shafts that I can remember, but never kept one! Why you ask? I have a electronic vehicle speed sensor on my 5 speed now, attached to the speedo cog output housing, and need to compute it's output frequency vs wheel speed. To get a ballpark number, I need the tooth count on the shaft gear to get the speed vs RPM data to enter into my Haltech tuning software. (I get my MPH from a GPS speedometer) If someone just happens to have …

Now that my 240 restoration is complete (well largely complete - is it ever complete complete?) I'm trying to clean up my garage. I knew I had two spare heads, but find that I actually over the past decade have accumulated four. Three are N42s while the other is E31. I have an N42 on the car. The only difference I can see is that the valves are a bit larger on the 42. I haven't measured the combustion chamber size, and don't know what differences there are in cams. I'd like to know which head is correct for my '71 HLSS30 28726,and what differences there are in terms of performance. Many thanks

Hello all. Dreaded Z newbie here. I've recently gotten a 260z motor and 280z 5 speed. I need clutch, pressure plate and flywheel to complete the package. I'm planning/hoping to put this engine in a non-Z car. Can anyone guide me on where to go from here? I don't even know enough yet to ask many questions, so any help will be appreciated. Thanks in advance

A while ago, I picked up an 83 ZX non-turbo and (with my recent calamity with my Z motor*), I've been working on pulling the motor with the intention of moving over into my 1977 Z. It's a stock F54/P79 combo and I'm not going to do a big time rebuild at this time, but I do want to do some clean-up and maybe some easy low hanging fruit improvements. I'm no engine expert and I'm going to have some questions for the collective along the way. I think there was a slight head gasket issue with the engine, so one of the things I wanted to do was replace that. Here's where I am right now. Head is off and block is stripped ready to be pulled from the donor car: So my fir…

A friend bought this 280z recently from a guy in Georgia and the temp gauge is too low by my thinking after a hard drive, I'm guessing PO put a 160*F thermostat in. My local Nissan dealer won't order in a thermostat but I found a Stant 195*F , wondering if it is worth a try? I thought I had a spare 180* but can't put my hands on it. Thanks

I have a early 1974 260z with e12/80 dissy .installed the msd 6a with the blaster 2 coil .could not get the tach working with the msd 8910 so I pickup the msd 8920 tach adaptor. tach works but there is a little bounce there and also when the headlights are turned on it stops for a moment. I hooked up the msd 4 wire tach adaptor as follows black ground, red 12v switch power, violet to blue wire from wire harness in car which is the tack wire, white to white wire from msd 6a and also connects to c term. on e12/80. msd is closed today . is this the correct hookup thanks kurt

Just beginning the resurrection project on the rear axles and related components. Removing the outboard axle nuts required some heat-red hot- to break loose after 40 plus years. I know new nuts and lock washers will be required, but what do you think about the bolts? The J.I.S. M10 hardware is a bit difficult to locate-14mm hex size-and the taller height nuts I believe will work in that spot. Interference nuts or regular nuts with lock washers? Just looking for recommendations on the best hardware options. I have got the new rubber boots and clamps already and will be pressing out the u-joints as time permits to size them up. Surprisingly the u-joints still feel pr…

I've successfully removed all the bolts securing this heat shield to the underside of the intake manifold, but it seems as though the EGR pipe (the pipe that is connected between the intake and exhaust manifolds) is blocking the heat shield from being able to be removed from the engine. I tried for several minutes trying to wiggle the heat shield out, but with no luck. The next logical step would be to remove the EGR pipe to get it out of the way, but everything I've read on this forum indicates that loosening the bolts that secure the EGR pipe is damn near impossible. Am I missing any trick to getting the heat shield out with the EGR pipe still installed?
