Morning all,
Hope we all had a great Christmas.
Just starting my 2.0 blacktop turbo build and was after some advice as to where to take an oil feed from to feed the turbo? I have the return line
sorted, just interested in where anyone has taken the feed from.
Thanks
Andy
There are two ways to do it.
Take a T from the low oil pressure switch.
Or how Ford did the Focus Rs.
There is a second blanking plug on the back of the block left of the low oil pressure switch. It's the same 1/4 npt fitting. Ford used a 1/4npt
to m10 adapter. You can buy a
1/4npt to m10 adapter on eBay.
1/4npt to m12 adapter on eBay.

I've already decided on the oil feed like wasa.
But, got any pics of the return to block? Interested to see how you've done that.
Cheers,
Steve

Are you going to fit a restrictor or run full glow to it.
You need a restrictor to stop it blowing past the seals dont ya???
Pretty sure the restrictor is in the oil inlet on my turbo. Will check.
Yeh I am sure the banjo in my td04 is restricted to around 1mm.
Oil returns from turbos should be below the normal oil level in the sump ideally,as if they are above the oil level crank case pressure can restrict the return of the oil from the turbo and cause issues with your turbo bearings/seals.
Ifnthe return is below the oil level would that not cause problems with surge in corners etc??

Surely if your breather system is pants it doesn't make any difference? Pressure on the oil pushes it down and up the pipe.. Gas pressure up the return will not hinder a dribble of oil as long as the return pipe is a good diameter.
I was under the impression the turbo oil drain should be just above the level of oil. The drain oil pressure from the turbo is very low and any
restriction will cause issues. Well that's what I'm planning on my mx5 turbo build as that's how most do it. Either into the sump above
oil or in through the dipstick hole.
Happy to be proven wrong tho.

Perhaps it just refers to big power Cosworth engines with lots of crank case pressure,as this was what I was running at the time.
Newer breather systems might not cause the crank case pressure problems.
