In my S4 turbo project I need to take oil to the turbo, and that at all times not only when the oil is warm....if you now what I mean. So I would like to know where I have a good cool oil source I can use. I've read about a restrictor, can you explain what that is and what it looks like, picture?
Is my oil cooler efficiant enough if engine is turbocharged?
How much tourqe can I get if 500Hk (on the engine)?
A suitable external fuelpump, suggestions?

The oil cooler circuit is bypassed when cold.

An easy way to get constant pressure would be an adapter plate between the oil fillter and block. (Oil filter sandwich plate.)

Remove the spring and cup for the cooler ports and port the oil right into the cover plate. Both my twin turbos get oil this way. You may, or may not need to install a restrictor...it depends on the turbo. I run -3 oil lines, teflon with braided shells...these are thin lines and seem to do the trick.

I found this oil filter sandwich plate, without thermo, how can I get the pressure down? Very large connections so the pressure will hoooooa in the turbo.
"Remove the spring and cup for the cooler ports and port the oil right into the cover plate." I dont understand, can you explain were you mean?
Im very interested.
