Oil pressure sending unit adapter
 

Hi guys im looking for the adapter that lets you install the MX5 sending unit in the LS block. Anyone know who makes it?

Sending unit is from a 2000 base Mata

This is the sort of thing it pays to know your NAPA guy by his first name. I can't tell you how many times I went in to my guy with a puzzle like this to solve. Just take your LS sensor and your Miata sensor in and tell em you have a puzzle for him to solve!

Just get an oil bypass plate threaded in whatever the miata size is.

Miata oil pressure sender is 1/8 bsp so if you want to replace the stock LS1 sender which is m16x1.5 then you'll probably need 2 adapters. McMaster p/n 4860k151 is 1/8 bsp female to 1/8 npt male, then there's a bunch of 1/8npt to m16 adapters available.

This adapter threads into the LS port, and uses your factory mazda sending unit.
