Need Help: My Turbo is toast!
 

I Was driving the other night and lost boost.

So I tore it apart and the turbo (factory) doesn't spin very well and the tolerances are bad.

SO: I have to replace it.

Questions:

1. Which turbo do I replace it with? I want a bolt on standard turbo - nothing exotic or performance oriented but it doesn't have to be factory. That being said, I know the new turbo's spool faster etc. I assume this is a K-27 but I know there are different versions.

What is the best source/vendor?

How much tuning is involved with tuning the CIS to the new turbo?



2. What are the "while you are in there" issues?

Should I replace the Turbocharger Oil Pump?

Rebuild the wastegate?

What else do I need to consider?


Thanks,

Well I dont know the condition of the rest of the parts, but...
I would check the turbo scavange pump and make sure it pumps well and as for the waste gate, if it aint broke dont fix it.
I would go to Brian (Rarlyl8) for the turbo weather it be a stocker or K-27- he is a good vender.
Converting to a k-27 isnt rocket science either.

If you go with a K27 vs. the stock 3LDZ, you'll want one of these:

It will allow you to couple the bottom end of the aluminum air pipe to the turbo.

As for a source/vendor, try contacting TurboKraft. Chris was a pleasure to deal with.

I have a freshly rebuilt K27s
 

This is from Ultimate Motorwerks. My turbo (at 800 miles) blue a seal because my scavenge pump was not working properly. I ended up rebuilding the motor and putting the stock exhaust (sold my headers), 3LDZ turbo and IC back on.

I have the K27S and Blown-Six IC for sale if interested. PM for details. I included a picture of when it was on my car with the headers. It cost me $650 to rebuild and it has zero miles on since. I have all the paperwork if needed.

Best of luck in the search,

Did the wheels rub on the housing? If not, why not rebuild it? New and reman wheels, shafts and bearings are available.
