I purchased a 'T' block, one 12.7mm (1/2 inch) barbed connector and two of the big barb connectors from Enzed this afternoon, also purchased a 12.7mm (1/2 inch) 'T' connector for the turbo oil return line, I might have to bend some tube for the big hose, my OEM breather didn't have the 90 degree bend it it like yours.
I had a look under the bonnet dark this afternoon, I have to relocate the battery isolator so I can move the Donaldson air cleaner further forward.
How are others connecting the air return between the air cleaner and the turbo, I was thinking of adding a large barb tap to the Donaldson tube that the air hose connects to.

SubscriberOn the aircleaner housing? From memory the air is filtered from the outside in so the only way to get to the post filter air is after the housing and pre-turbo.. Although I guess you could have it pre-filter? Doesn't seem right though..Originally Posted by The Mutt

^ yes this would work^
I just connected my air return the other day. On mine I have a short bit (~100mm) of 3" stainless tube connecting the two 3" silicon hoses between air cleaner and turbo. I simply drilled an 1" hole and welded an 1" gal steel barb to it. I used a bit of 1" oil resistant hose to join to provent. I welded the barb on at an angle to suit.
Cheers, Andrew.

Has any one considered an exhaust ejector for the road draft system
Probably a nutcase idear and not legal but no hot oil smell
I have 3 inch spiral air line connecting the air cleaner and the turbo, it has wire embedded in the spiral to keep it from collapsing, I'm thinking of cutting a hole into it and riveting plates either side so that a return air connection can be added. Would have already been done, had to go to Wagga Wagga for a few days on business.

Want to weld me one of those?
This is one of the pieces I can't figure out how to buy or make without a welder.

SubscriberWhat diameter intake are you running? If its 3" you're probably in luck (assuming I've still got some 1" stainless around somewhere).

Flick me a PM with diameter and how long you need the intake piece (or I can just allow 30mm or so each side of the 1" for clamping to).

SubscriberI wish I had more room between the turbo and the cleaner.. I'm going to have to do something with the cobra.

SubscriberI'm almost ready to give up due to space, there is very little room between my air filter and turbo.
Is there anything wrong with connecting the air return pre air filter? Even when hot and driven at 22psi there is no noticeable residue in the outlet. It is just a matter of space
