TD04 oil feed
Hi, I have a mk1 eunos and im installing a TD04L from a subaru on my 1.6. I have a -4AN steel braided oil feed pipe but was unsure whether it needs a oil restrictor.
do TD04 turbochargers need a restrictor, I was told journal bearing turbos wont need them but it wasn't a reliable source
can anybody help me?
thank you in advance

Sturovo, who supports lots of TD04 installs, counseled me to do so. I used a 1.5mm restrictor built into the -4AN adaptor at the CHRA and have had no issues in about 3k miles.

Good info Joe and David.
I think it should be possible to run the run the Subaru 13t without a restrictor looking at the CHRA oil ways.
The pathways to the bearing and thrust surfaces are small (~ 1-2 mm) and once the oil reaches the shaft the clearance for the oil to escape is tiny.
I tested the oil flow through a TD04 with and without a restrictor and there was no significant difference. As Vlad pointed out Subaru use a 1.5mm restrictor with this turbo so for peace of mind I use one also.

that's great news! thank you everybody! just bought a 1.5mm restrictor, hopefully should arrive soon!
I was told that a 3AN line I wouldn't need a restrictor but because as im running a 4AN id need one
I was told this from a local mechanic but ive seen his work before and I didn't trust his advice on this.

1) I will edit my post. I looked, and I also used a 1.5mm dia restrictor / adaptor as well, NOT 1.0mm
2) I think you made a wise choice to use a -4AN and restrictor rather than relying on tubing size and length.
3) Sturovo, thanks for the further research.

just a quick question everybody, I received my restrictor today and the turbo is no longer burning ANY oil so im happy however there is a leak I cant figure out why.
I bought a
M10x1.5 1.5mm restrictor adapting to a 4AN fitting perfect for the oil feed line to attach to, however it is leaking I believe from where the pipe joins the fitting. and ive tightened it as much as I dare but its the same.
Is there anything high temperature I can apply to the threads to seal it?
