S14 Oil Pressure Gauge Install Question.

[BoBa524]

So, i got a prosport oil pressure gauge(electronic.) I need help finding out what the thread size of the stock oil pressure switch. I want to run both, stock and this gauge. looking for suggestions on what i can pick up from a local hardware store maybe.

this is the sending unit.

with more searching it looks like SRs use a 1/8bsp thread, right?

Yes. Nismo sells a T so you can run both sensors but its a very tight fit with the intake many brace. I think prosport sells adapters if the sending unit threads are not 1/8 bsp.

i got a t fitting and two other fittings in order to run both sensors. but it barely clears because of the intake manifold bracket. Got it to work tho, however, i broke the connector to the factory switch so ill just get a conversion fitting for the gauge and just run that. oil pressure light just doesnt light up anymore when you start the car.

could you post a pic of the setup. You said you used some other fittings what were the specs on them.

this is what i got, the engine uses 1/8 bsp threadbut the sensor uses 1/8 npt thread. I got a T fitting from home depot and its 1/8 npt thread. like this:

so then i had to to get a male-male fitting that was bsp-npt like this:

then i hat to get a fitting for the stock sensor(bsp thread) to screw into the T which is an npt thread. like this:

my stock sensor is touching a water hose that i believe goes into the heater core. i wanted to keep the stock switch working, but after braking the connector i just realized it was useless, so i will just get one fitting for gauge sensor to engine block.
