Im wanting to replace my turbo. Car just hit 80,000 miles. Any suggestions on which turbo to go with? I'm having boost issues and the valve cover has been replaced, coil packs, spark plugs, Maf is clean and all the pcv hoses/pcv system is clear. The car isn't throwing any codes but I want to replace the turbo. It doesn't have the boost it used too. Thanks.
 
How did you measure the boost? How did you check if the system held pressure? I made myself a pressure tester for about $15 when I suspected a leak. I had a couple minor leaks and tightening a few clamps fixed it.

I monitor my boost with the Torque APP. Max I've seen is 13.6 PSI under heavy acceleration but most of the time it never goes over 8 PSI.

You will need a similar turbo with internal waste gate, you can order aftermarket for a good price..


Or if you just need the housing.


Or if you think you just need the turbo...

I didn't measure it. I just wanted a recommendation for a turbo replacement. But it also won't Rev passed 4000 rpms. But maybe that's normal idk lol
 
It's just when I'm parked and in neutral. I can't remember if thats normal lmao
 
Why would you replace it without first doing any testing of the current turbo?
 
Do u have any recommendations for a turbo replacement?
Ebay has them for about $250. Also MelsRegal, it is not uncommon for these turbos to go out well before 80K miles.

Unless you've really been bad on maintenance it probably isn't the turbo. Check the electric boost controller and bypass valve first. Those are more likely the culprit
 
That was before GM went to full synthetic and the new revised oil feed line.

When did they switch to the revised oil line and full synthetic?

Where are those components? Bypass valve and boost controller? Can they be replaced?

Thank u I'll buy the part. Do I need to drain the coolant and oil to replace this part?
 
Don't buy the part if it isn't defective. Check for cracked lines or leaks first. And no need to to drain anything these are vacuum lines you see.
