hi

got the omori mechanical oil pressure guage, it reads pressure between 2 at hot idle and 7 at cold high rpm

but the needle vibrates like its getting small pressure pulses, it vibrates about 1mm at the needle tip at all pressures probly more noticeable when hot.

it wasnt hooked up when i got the car and is now connected to a port in the remote oil filter.

I had to make the fitting because it was missing, I might be answering my own question here, the fitting i made has no restrictor, i remember the mech guage i had on my old eh had a really small hole in the fitting possibly to stop pulsation from the oil pump

Im a bit concerned I read on here that a cracked oil pump gear will cause pulsing oil pressure.

    • I'm actually not sure - I think it was "Stealth Performance" (It really is near impossible to find a FEMALE 1/8BSPT to 1/8NPT male at ALL) but having the thing leveraged on a 90 degree angle on a small aluminium fitting is not too smart. Also in not too smart, I've drilled out the center of the broken fitting so there's maybe 0.00001mm of thread to bite into, so yeah. I may have to get it drilled/tapped/plugged entirely. Given I could conceivably tap a thread/adapter/pressure line in any point in the oil system I suppose it's feasible to run a line to the Nissan Sensor to keep the dash working. Do these exist in AN fittings and the like? Like an AN fitting that has a NPT (or other?) thread as well for putting a sensor in?
    • I would agree.  There will be an amount of boost you could run safely with an otherwise factory system, but it would be low enough to not be worth the cost.  And if you are reliving your 20s, you know a 'little bit' was never enough. Personally, if I didn't want to spend the money, then stick with NA bolt-ons, and maybe a tune.
    • Fuark, at least the motor survived. What brand was the fitting that snapped?
    • Wrong question. There's no point in spending the rather large sum of cash and effort to add turbo, without taking it to the "sensible" limit of the motor itself. If you have to upgrade injectors, etc, then so be it. That is a tiny fraction of what it will cost you to turbo it.
    • Measure voltage at the starter solenoid terminal when the key is at start and it has clicked. If it is really low, then the suspicion falls on the ignition switch (contacts or wiring thereof) as causing a voltage drop instead of sending enough volts to throw the solenoid all the way to engage the starter itself. If it is a decent voltage, then the suspicion is on the solenoid. Might have s horted coil, or might hva dirty contacts. Rip the starter off, dismantle, clean up contacts and inspect winding. It might not be possible to see if there is a short in the winding though. I have a spare starter here that I could measure the resistance of the coil, as a guide to about what it should be, if you need a comparison. <parts hoarder>No you cannot have it.</parts hoarder>
