Totally new to this forum, so please excuse me if this is posted in a wrong section.

I need to supply pressurized oil to my turbo for my 95 RS (420a engine) project. I found the oil pressure sending unit right above the oil filter, but it's nothing like I've seen before. There was just ONE bolt to remove. Then I just pulled out the sensor; it was a smooth cylinder and it was magnetic. All the units that I've seen are threaded. I don't think I want to tap the hole and possibly get shavings in my block.

Is there another way to get oil to my turbo, like a threaded place somewhere on the block that's blocked off by a bolt or cap?

Everything's bolted up, this is what is setting me back from starting to tune!!!!!!!!!

That's the crank angle sensor. The oil pressure switch is on the far left side of the block when laying under it looking up. You won't see it the first time you look. There's three sensors back there from left to right: Oil pressure switch, knock sensor, crank angle sensor. The oil pressure switch is on the far left side above the axle shaft. You'll need a deep socket 1&1/16", or an "oil pressure switch removal socket" that you can get at AutoZone for about $7.

Thank you very much with the help. I'll check it out. I figured it was a bit wierd for it not to be threaded.
