If you could mount the turbo higher than the valve cover, you could drill a hole in the oil fill cap, say 1/2", and just stick the turbo drain tube in that hole. Way easier than drilling a hole in the oil pan..plus you'd also have to tap it and buy a fitting. This may interfere with the hood tho..

Maybe this is more helpful

 

Oh yes. Turbo not hit block.

 

We have already helped you. The members of this forum routinely share their build threads and their new ideas. Some of the oldest members have dedicated hours and hours to writing basic DIY and FAQ threads that are easily found through the search function. This forum is a tremendous wealth of knowledge and it is open to you.

Let me assure you that the answer to your question can easily be found on this forum. Instead of utilizing the search function and looking up the answer to your question, you chose to post a thread asking a question that has been answered over and over in the past. In our eyes, this makes you entitled, and we hate entitled people here. Instead of doing the work for yourself, you asked us to spend our time to make your life easy.

The reason this forum is so great is because new users are strongly discouraged from asking basic questions. This may seem counterintuitive, but the result is a forum which is constantly discussing new ideas, instead of rehashing the same basic questions.

If you are interested in being a contributing member here, the world is your oyster. The search function is available to you, and the majority of your questions will be answered there. I still use it on a routine basis to brush up on old topics or catch up on a new topic. If you can't be bothered to do your own research, and you expect us to help you with every single question, then perhaps this is not the community for you.

 

Let's try a pictorial approach...

Oil, check. Sandwich plate,check. Feed? Yes please.

 

You are doing it wrong.

Don't use a sandwich plate for the turbo oil supply. Use a tee on the oil pressure sensor port on the block.

 

So i use a sandwich plate.
Turbo receives oil through one of the 3/8 holes and its plumbed back into pan directly.

Nothing else is on the sandwich plate.

Engine has oil. (Mine spits out the valve cover)
Turbo has oil. (Added a reducer to stop blue smoke)
They both empty into pan.

Oil temp never been hot.

Why is this bad?
Car has done around 5k without an issue.

 

Your sandwich plate is different than most, then. Most sandwich plates direct all of the oil coming from the oil pump into whatever is attached to the plate. Usually that's an oil cooler. It's never a turbo. If you don't hook both sides up, you grenade the motor.

 

OP go read the FM install manual.

 

General question to this topic:
I bought a turbo kit which connects to the back of the vvt 1,9 engine head. The oil-supply line is connected to a hole near the exhaust-cam. normally this hole is plugged with a headless-screw. Any thoughts about this oil-supply technique?

 

Don't let all these haters get you down OP! Try it out and show everyone else they're wrong.

 

I think the problem is that some brands of "sensor adapter plates" label their product as a "sandwich plate". Like the fine folks at Mishimoto, who sell both styles and call them both the same thing

 

There's a thread about that; https://www.miataturbo.net/diy-turbo...ey-plug-75112/

 

Those are designed for two different porpoises.

 

Mines the first dolphin.
Thanks - The dolphin fins made me not panic as i remember the pattern.

 

The bottom one is made to send all of the oil through a cooler or remote filter through the large ports. The top sandwich plate is designed to allow sensors and low-volume oil feeds such as turbos to receive some oil from the outlets.
