Default Turbo oil feed

I'm have an ls2 from a gto in a 240sx and looking for a place to run an oil feed for the turbo. It is running a different oil pan so no oil feed option from the oil filter housing. I'm not to keen on using the oil pressure sender port at the back of the block so were else could i get a good oil feed for a turbo on the motor.

I wouldn't use the galley plug at the front of the block because it's unfiltered oil.

Since you don't have the oil pan adapter, your options are basically the galley plug just above the oil filter, though it's a little difficult to access, or the port behind the intake manifold. Another option is to add a filter sandwich plate. If you're running an oil cooler, you can also tee it off one of the oil cooler lines.

I just tapped my truck oil fitting and ran a -04 line to turbo. I was almost going to tee off of oil pressure port behind the intake also but the bottom end gets oil first.

The bottom end gets oil first ?

Pressure can only be created when the entire system is filled and all oil meet the restriction that is bearing clearances etc....

And oil is fed directly from the pump...to filter, from filter directly up past the barbell to the area where the stock oil sender is, and then down the main galleries/drillings to any bearings.

If you look at the link I posted, inline oil filters were added after the galley plug and before the turbo.

I missed that, but yes if you use that galley then I would add a filter to protect the turbo.

Where is the port on the oil pan... Next to the filter and you are saying a engine does not drain down? Today's lesson is?

What port and on what oil pan ? There are many and the OP has not stated which he is using.

And any drain down is negligible.
