yeah i would be a bit concerned about not having a restrictor, dunno if that turbo needs one or not, i always understood that the turbos hardly used any oil. i totally agree tho, on my gfs cabby at idle with the sensor on the head and fairly light oil there is almost a full bar of pressure, and when ur on it, there is nearly 1 bar for every 1k rpms. and i like to wind that 10:1 8v out haha.

By the looks of it in the picture, that oil return line will be right in the way of the cv axle. (it could just be the angle of the photo). But it would definatley be somthing to check.
Im not sure if this has been brought up already, but I didnt see it.

Yeah that oil return needs to hug the block as much as possible.
Here's a pic of mine with a similar setup.

that the first thing I checked guys and it's TOTALLY the angle of the picture. That line is millimeters away from the block.

My 1z is factory fed from the sender port on the end of the head so at some point even vw thought there was enough there!

I would be concerned about reducing the oil pressure to the rest of the drivetrain by taking oil from there, especially without a restricter.

Well considering the fact that the factory runs a HUGE line to the turbo and I've pulled it back some from that...I'm not worried. Have any of you ever seen the size of the oil line from a factory k03...it's almost .25 I swear. This motor is not expected to have a long life anyway. I will kill it some way or another:)

That has to be your signature. Seriously one of the best quotes here.

it doesn't matter if I rob oil from the head or the oil filter housing...I'm still robbing oil pressure.
And I know I'm not the first to turbo a 1.5:)
It's not like this is a 20vT that suffers from sludge or something. This is just a 1.5D I got for free.
Anyway...enough doubting. I'm one of those guys that builds the *** and if it breaks...I fix it and keep going.

when it breaks autopsy of dead parts will tell us all how to do it better next time!

Yeah...good point. I care more for the t15 for sure:)
I have a few spare engines out back. Did any 8V gassers have larger pumps? I know for fact I have a 16V pump out back too. I just thought all 4 cyl blocks were created equal as far as oil pressure was concerned.

IIRC, the 1.5 motors had 26mm oil pump gears. The AAZ/1Z has 36mm oil pump gears. That's a huge difference in oil flow. It seems you might have appropriate expectations.
i used a TD oil pump whenever i did a turbo conversion.. the 1.5 engines DO have tiny little oil pumps..

well I have a few 1.6 diesels out back. Are they any better?

i pulled 26mm pumps out of my early 1.6L engines too..

It depends on the year. The hydro non-turbo 1.6s had 30mm pumps which are better than the 26mm pumps.
i think the n/a solid lifter engines got 26mm.
hydro n/a and solid lifter TD got 30mm pump. 30mm pump will supply enough oil for a turbo on a solid lifter engine..
hydro TD and AAZ got the 36mm pump.
pretty sure thats what came in those engines IIRC.. someone feel free to correct me if im wrong?
