So I have an 87 4runner dlx and just got a 89 sr5 with the 3.0 v6 for parts like 1/4 panel and interior and cluster and was just wondering if the oil pressure sending unit will fit on my 22re

I had a 22r and I remember it being 1/8NPT. The 3.0L is 1/8NPT as well. Question of fit physically yes I would say, But calibration wise is something I would not be able to tell you.

How do u make the tach for the v6 work on the 4 cylinder

actually, whatever the size is, it's probably not 1/8" NPT. It is probably 1/8" BSPT, which is similar in diameter but not the same pitch. MudHippy has dug up a possibly-obsolete Japanese standard that gives the 1/8" BSPT a different name.

The good news: whatever size it actually is, all the oil pressure sending units are the same connection. As long as you're not trying to buy a tap.

The adjustment potentiometer:


if you have another tach hooked up that you're using to adjust, you can sneak a thin and long screw driver in there to adjust it (I had to gently push against the pot with the driver to bend it back slightly and seat, but this shouldn't cause any harm.)

if you don't have another tach to adjust by then you can pull it out by removing these 3 screws:


then use your multimeter to measure resistance across these two points:


The V6 was originally setup with a value of 44.9K ohms, I adjusted it to 63.8K ohms. I would recommend people converting a 6cyl cluster to a 4cyl to simply add 20K ohms to whatever they started with.
