Hi,

I am getting a new turbo for my 98' Audi A4 1.8T. The car has 205k miles on it and turbo is not blown yet. But there is no boost and turbo is consuming lot of oil. Mechanic figured out that turbo is going bad and need to replace.

So I'm planning to get an OEM replacement turbo from ebay.
My concerns are;

1.Will a new turbo cause damage to an old engine?

2. What all parts do i need to replace when putting new turbo? ( N75 valve, oil liners etc??)

Please reply. Thanks

 

My suggestion is to not get a turbo from eBay.

There are a lot of GREAT and informative FAQ's on this website that will answer most of your questions, I suggest you read through them, you will learn a lot about these cars.

But I will say (like srlito said) that Ebay turbos are badnewsbears. They're usually poorly balanced and made of substandard materials, they will break, and they can damage your engine. Also a new turbo will not do any damage to your 200k+ engine as long as it is a DIRECT STOCK replacement (i.e. no upgrades).

if you want a new turbo since your on a stock ko3 upgrade to a ko4 for the same price as a ko3 its stock replacement bolts on as a factory ko3

RP K04-0015 - K04 Audi Longitudinal 1.8T

 

Don't get an RP K04; there's been enough stories about those blowing within a couple months of use. That's probably why it says out of stock on Mike's site

Thanks for the fast replies.

I AM NOT GETTING CHEAP EBAY TURBOS after reading your suggestions above.

I found this remanufactured borg warner turbo on ebay;

KKK K03 Rebuilt Turbocharger VW Passat 1.8T Turbo | eBay

And a new borg warner

GENUINE NEW BORG WARNER TURBOCHARGER VW PASSAT AUDI A4 | eBay

How about these two?

Also can somebody tell about gaskets and other parts I need to replace while putting new turbo?
