Excellent write up btw.

I understand the issue about moving the filter tip down around and inch or so, but for me it was a convenience factor. No measuring of threads, adapter fittings, or finding the right plugs. I just installed the pressure transducer to the block and installed it at the next oil change. Like I had said, just my .02
As for the gauges not fitting the block, you could always have used reducers to make it work, or retapped the hole in the filter block. I just was amazed on how easy it was for me. I have a greddy block and defi bf oil press gauge.
But like I said earlier, nice writeup.

Just an update. I ordered the fitting I linked to above. The install was really easy. The pieces fit perfectly. I used teflon tape to seal it all up, and haven't had any leaks. I have no idea what size and pitch the threads are, but it seems like a good, easy solution.
OK, here's one for you.. Are you getting the oil temp before or after the oil goes through the cooler?
FYI, the lower plug is in the return from the oil cooler. With a VDO oil temp sender installed in this hole, with the 42 adaptor, I see 180f on the street. On long track runs the temp held at 240f.

Just to let you know my experience. I had to go back and re-do the fitting using a sealant instead of tape. The tape started to leak a little on me. However, it could be because I didn't have enough on there, or something. The fitting is great.
Twan, I'm not sure about the locktite. If it is fine with oil, then it should be okay. I used some type of blue RTV from Autozone when I fixed mine. Someone else I talked to said his leaked with the sealant, so he fixed it with tape. I have no clue what type of sealant he used, or how long he let it dry before filling up with oil, though.

One of the standards has one more thread per inch than the other. So they are close, but not the same. The fitting above works fine for Defi. The one side threads into the car, and the other end is 1/8 NPT, which seems to be pretty much standard for aftermarket oil gauge fittings.
after reading that install, i'd be scared. Most places will recommend a remote mounting of a sender, as i did my on rsx. Basically, you come out and run a line to the T, then mount the sendor. When the engine is revving, bouncing, moving, all the weight and stress of that sender is on the threads.
I may be over-stating my concern, because the block on the 4g63 is Iron, where as the k-series is aluminium.
regardless, remote mounting, can't be a bad idea.

NPT = National Pipe Thread
BSPT = British Standard Pipe Thread
Maybe it's JPT, Japanese Pipe Thread.
Chances are it's 3/8 NPT
For anyone that doesn't know, pipe thread is progressive so it's diameter gets larger the further it threads in. Basically if it's leaking then it probably isn't tight enough.
I don't get oil pressure readings right off the pump, once it goes low the damage is done. Tap the oil pressure off the head and it will read lower but it also starts to drop if there is any problems on the bottom end. You know your losing pressure this way instead of the audible low oil pressure method.
