So I've read a bit of this thread:

https://www.miataturbo.net/build-thr...t-70781/page4/

and this thread:

https://www.miataturbo.net/engine-pe...ocation-73987/


And I'm left confused. I have two questions I'd like a rock solid answer on:

What thread type is an NA oil pressure sensor?

What thread type is an NB oil pressure switch?

For some reason I feel like I'm finding out one is BSP(T?) and one is NPT, but I'm unsure if I need an adapter like this:

1/8 NPT female to 1/8 BSPT male Adapter

Or are they both the same? Cause at the same time I feel like if they were different I'd see the correct info all over the swap threads.

Thanks.

 

All the same thread AFAIK. The block port is BSPP, the sensor is BSPT.
