how do you tell if you have the k03 or k04? my car was modded up the *** before i purchased it.... im boosting a nice 24-25psi what would they look like under the hood?

 

If it is a K03 or K04 you will find that info on the blue plate on the front of the turbo.

Just like you see here.

 

sweet, ill have to take a look at that! and ill assume the k04 would read kk4?

 

No. THat is the logo of the company. The turbo used to have a triangle on it with KKK, but that then got changed to a single K in the triangle.


Here is a picture of a K04-15



Here is a picture of the older 3k housings.
