Does anyone know off hand what the tightening torque should be for the header nuts on a 75 280? Also, wonder if there would be any problem with using stainless steel nuts and washers on the factory studs? I've searched the FSM and found the specs for the intake but not the exhaust. Bryan

Hello guys A friend of mine has a L24E (810 motor) that is sitting on his property. This next week I'm going to be replacing the oil pan gasket on my L28E (280z) and I'm wondering if the two oil pans are interchangeable. I was going to remove one (off the 810) clean and paint it and put it on when I replace mine. Thanks Jan

I have a late '73 (7/73 I believe) with an L28 and an electric fuel pump. The power for the pump, which is located in the engine bay, comes off the ignition coil feed. I would like to reroute this so that there is no parasitic drain off the distributor current, and I'd also like to put in a cutoff for safety and theft purposes. Does anyone have a suggestion where I should intercept the harness so that can put kill switch in the cab, and still have it switched to the ignition? Thanks.

i had a 78 stock engine and tranny combo and then removed the engine for an f54 flat top with a fidanza flywheel, i chose to reuse the previously good clutch and pp with some issues lining up the old pp to the flywheel. upon start up there is a slight squealing noise coming from the bellhousing and when i depress the pedal the noise is gone. once warmed up the noise is constant with pedal depressed or not and have noticed rougher feel when engaging gears with reverse being a complete nightmare. i am leaning to the idea of the pressure plate being the culprit as it is the 225mm and i have recently been told the flywheel requires a 240mm. would that cause the squealing?

Ok, so I'm going to put the 4-speed and R180 I have up for sale since I don't intend to use them. Just to clarify, there is no way to readily identify the specific year or anything else about the gearbox based on the numbers stamped on it, right? I just have to say "Datsun 4-speed for sale" and go with it? Thanks, guys

Ok I own a 74 260z bone stock but the dual webbers. The car has been burning oil blowing gaskets here and there and is just plain worn out. So I decided to pull the motor and do a complete rebuild. But I was thinking about doing a turbo on it. I have rebuilt motors in the past even 3 280s. But I have not much knowledge on turbos to be honest. My question is what would i have to do to make my non turbo motor a turbo motor but still hold up for reliability. I know how to rebuild to stock. But i'm not really good with the performance part to make it better. Basically I want I want is to find a way to get a 13 second street car wether it being turboed or not. Reason is my old…

On the 71. Seems to read about halfway between that half point mark and the highest reading. This after car fully warmed up and cruising at 3000 RPM. Then goes back to just above halfway marker at idle. It is higher than it used to be.I don't know if this is something to be concerned about our not. Maybe just the sender? Think it means anything bad?

I was planning on removing my head on my stock '78 today, in pursuit of a suspected blown head gasket. I removed the throttle body (don't ask me why) after removing the plugs and rocker cover, and discovered that it was soaking wet on the back of the butterfly. I had previously removed by BCDD , but still had the vacuum line to the EGR system attached. I was able to pour water from the bottom of my throttle body, in the orifices that lead to the now removed BCDD. There was no moisture in the area where the vacuum is applied to the rocker cover. The only source of coolant in the area it appears, is the vacuum line to the EGR system. This line leads to a valve that is te…

Thinking of buying several timing kits that are made in Japan. The kits are labeled for a 260z. Am I correct in thinking that the only difference in the 70-78 kits is that the Slack side chain guide is different? Anyone know what makes the guide different? Can a pre 75 slack side guide be used on an L28? I'm thinking the newer guides must be an improved design?
