Question replacement turbo vs upgrade turbo

Hello fellow mazdaspeed 6 owners,


I am looking to replace my stock turbo because of the defect found on the factory turbo. I have heard that the seals will go along with oil inside the turbo also. I wanted to know if I should just get a replacement turbo or is it really worth buying a upgraded turbo? I don't have a lot of mods just a turbo back exhaust, Hyper tech chip, top mount intercooler, and a HKS BOV. I have done my research on trying to find out what is worth my money to buy a upgrade or just get a brand new OEM KO4 turbo and call it a day. I thank you all for reading and helping me out with this issue.

Upgrade turbos will definitely be harder on your engine and transmission.
Click on this: Turbo-Kits.com - Mazdaspeed6 Mazdaspeed 6 Turbo Upgrades - MZR See top one, click on "Frequently Asked Questions" then go to bottom of page----they discuss reasons why your turbo is using oil.
I searched "turbo upgrade mazdaspeed 6"

was looking for a stock KO4. IK for sure if I get one of these kits it will just make more headaches for me in the long run.

The second item is a K04. Please read "Frequently asked questions" under either of the items as they are the same and discuss generalities to why oil is being used, so you maybe can figure out something that Mazda missed. It won't let me copy & paste. http://www.turbo-kits.com/turbo_kits_faqs.html scroll to bottom, very good points---1 is adequate crankcase ventilation which tells me you should your PCV valve often.

Default Leaks?

I have an 07 speed6 and the boost is reading 5 psi. I'm assuming there's a leak. Any ideas where it could be coming form or on how to fix it?

I would check the intercooler and pipes associated with it. Could be bad weld that has let go or small hole. Check all connectors.

I check the inter cooler piping and there doesn't seem to be a leak. Could the be a problem with the waste gate or blow off valve.

What are you using to read the boost? & where is it reading from?

Did you take it off and pressure test it? Leak down test?
Trying to listen to it with engine running isn't the way to check it! This is not a simple check! The intercooler is like a rad, many connections.

A boost gauge, not sure where it's reading from. It was running around 5psi when I got it two weeks ago now it's down to three and won't hold pressure.
