Garrett GT28 Banjo Bolt Oil Restrictor Size

[Lukezen27]

Guys

Anyone see any problems tested the oil feel line bolt withput actually bolting up the manifold?

I have everything still connected but the turbo and manifold cable tied to where the a/c radiator should go..

it wont hurt anything, but i wouldent run it for too long, it will sound terrible and probably wont run smoothly but should be fine just to test the oil flow for a minute or so.

Yeh should be fine to run. Its very loud and rough though.

To save any confusion, for best results when using a Garrett GT turbo,
Use a 0.6mm restrictor in the oil feed line.
Be mindful the following should also apply,
The oil drain must be of adequate size & free flowing without kinks or dips.
Try to drain back to sump above the oil level.
The B16A~B16B~B18C lend themselves well to this with an available boss on the block that can be drilled & tapped to accommodate an AN fitting.
(To the left of the dip stick – lower portion of block)
Also, don't mount the turbo more than 15deg off horizontal - shaft orientation.

If the GT is leaking from the rear, fit the restrictor & it should fix itself…
The rear seal is carbon.
If it’s from the front, Bad luck

Hope that helps

Thanks Adrian

The smallest I could find was 1mm and I've installed that, no more smoking out the tail pipie

Where can we get the 0.6m restrictor?

Mine was leaking both front and back

Hey Luke, the chap we saw said he had a smaller one (smaller than 1mm) so if you still need it you could go down. I'm pretty sure he said it was .6mm.
