Doc since you have the RS2 turbo I have a question. Does this turbo look identical to the K26?

 

Pretty much it is a K26. Markings on it are K26-7200...

Read the Clarks Garage DIY, it's something I can do, but doubt I'll have enough time strung together to knock it out quickly. I may punt on this one just so I can have the turbo off the car and getting rebuilt asap.

 

Doc the only issue I see in removing the turbo is patience and time. Also it seems your turbo was just swapped therefore if the shop that replaced it, added Antiseize to the bolts you should be fine.

 

Patience I can do, time, not so much. Between working and family I have limited time to work on the car.

 

Funny, so it looks like that the turbo is a 7200 compressor with a 26/x hot side.

 

Yep, it's nothing special, no "Secret Sauce".

 

Doc you have to look at the bright side, you have a healthy engine. All you have to do now is to get that turbo rebuilt and then enjoy the car again. I think I have the same issue as you with my K26/6. So I think is time to throw the 27/6 that I have laying arround in there. Keep us posted.

Oh, I'm very happy that there are no motor issues. That would've spelled the end of the season for me and me yanking the motor in favor of an LS1.

Just have to take this turbo off and get it rebuilt, then back on the car..

 

Doc, get in contact with John and see who he uses. you may just be able to send it directly to his guy. If not, he'll steer you in the right direction.

 

Josh:

I just sent you an email with more info. Recommend you try the oil line restrictor before pulling off the turbo.

 

Yup, I think that it's worth to try that.

 

Get a new bung for the wideband sensor downstream of the turbo as well. Wideband sensors dont do well with the heat AND pressure that are pre turbo. Their sensing cells are more complex and delicate than narrowbands, which is why they cant go pre turbo.

And the sensor must be angled upwards towards the roof of the car by at least 10 degrees from horizontal, basically the end with the wires must be higher than the end in the exhaust. It CANT be perfectly horizontal, or wires end lower than the sensing end. This prevents fluid from collecting and ruining the sensor.

 

Yep, might as well check for the restrictor and install it and see what happens. Worst case need to send the turbo off for a rebuild anyways.

I can get to the oil feed line by removing the intake mani, but don't need to remove the turbo itself?

 

Yes, the oil supply line is on top of the turbo, between turbo and intake.

Beware theres an oring under there on the turbo, and youll need two 12mm crush washers at the banjo bolt on the balance shaft housing.

 

Turbine/compressor seals frequently fail from overpressure, the same thing that blows hoses off.
How are you measuring pressure?
Is it calibrated?
