UrS4 2.2T Sedan project

[s0_big]

Hi!
Did the first test with the car yesterday. Car drove wery well and feels nice. Unfortunately my turbo is still leaking (on the same place as before the repair). I got info from some guys and they told me that maybe i need a oil feed restrictor. I ordered a 2mm restrictor to try out if it will solve my leak.. Do any body else here needed to fit an oil restrictor to a journal bearing turbo? A little bit mad at my turbo at the moment.

I run with a AN 10. Worked good for 2 tears.

The car is not dead (not me either) been to much work and to little playtime... I installed a 3mm restrictor on the oil feed line to the turbo but it still leaks just a little.. I will try to live with that until i buy a new turbo some time. Made a little video of my testdrive yesterday with my new Gopro Hero 6. Further on i will try to get the car ready for MOT and hopfully they will let it through this time to. But we will find out soon

The car has been on holiday.. My turbo problem still hanging on and I don't want to risk the car to catch fire. Easy solution, buy a new precision 5858 turbo which I will do after my holiday to USA. Sorry for the lack of progress. But as soon as I order the new turbo i will let you guys know. Just need to work in the money after that the car will get MOT as soon as possible.

I think, that 3mm is still too much..I have journal bearing turbo too, but i have around 1-1,5mm (AN4 feed) inlet and AN10 outlet

One of my favorite builds of all time! I always come back to go through your build. I hope that someday mine will come out this nice!

Thanks you for the kind words. It sure will, just put a lot of time and effort in to it and it will happen
I hope I can afford to buy a new turbo so I can run it this summer. My other project (RS2) take most of my time and money right now. But the Urs4 is sleeping well in the garage.. I have to start it up some day soon.

Finally, i have put an order on a new turbo for the Urs4 =) Will be the same turbo. Precision 58/58 journal bearing. Hopfully it will arrive before easter. This summer it will run many fast miles for sure!
