Oil feed & Return Questions

[eckoxl]

Ok. For my turbo I plan on tapping off the oil pressure sensor. Anyone know what size fitting that I would need for a tee fitting?

Then for the return, is there an oil gallery that I can just remove the plug from and tap in there? I was planning on just tapping the oil pan, but I wanted to see if there was a gallery in the block i could tap into.

This looks promising...

The only other consideration is routing the oil line(s) so they do not impinge on the headers or other exhaust components that might cook the motor oil even hotter than it gets during the heat transfer inside the turbo. Woven Fiberglas Header Wrap comes in 1" and 2" widths and would be very handy to have in protecting the line(s) in the areas where close quarters might prevent you from arranging home made stand off brackets. HarborFreight sells inexpensive Stainless Steel ties that can be used very creatively when trying to wrap and contain exhaust manifold parts that add so much additional temperature under the hood. In racing configurations... having an oil cooler may be the only thing that allows high performance turbochargers from bearing failure as well as engine component breakdown. The best analogy for this comes from the idea of taking an ice cold Diet Coke from a cooler filled with ice and throwing it up on the BBQ until it nearly boils to bursting...and then trying to drink it... What it would taste like when it was cold is nothing like the brown, boiled and useless liquid that would be in the can on the BBQ. The oil that circulates through the roller bearing chamber on the "hot" side of your turbo is much the same...and before it gets poured back into the engine to get re-cycled again and again...it deserves to be much cooler. And if it is... it will continue to protect the internal engine components as well while on its trek through the oiling system.

This is just off my head from YEARS ago when i did mine but 1/4"NTP for some reason rings a bell...

This has nothing to do with my question.

Anyone have any experience with using an oil filter sandwich?

Like this

Then just using the inlet for the return line?

[RedZMonte]

i dont think that will work.... The oil filter and adaptor is all pressurized from what i understand, the return from the turbo is gravity fed... so it wouldnt flow enough back out and cause the oil to back up.... maybe even push oil up to the turbo..... I don't like to reinvent the wheel, there is a reason that eveyone including OEM tap the pan for the return...

Well it's either blast a hole in the pan for the return or go like I did and get a scavenge pump ! Works great !

Here is a good drawing of the oil feed. http://groomlakelabs.com/index.php?q...g2_itemId=2554

As far as the return goes I would just tap the pan.
