Does anyone have information about our turbos. Im looking into doing a K03 swap cause i have one laying around. I want to know if the K03 would help the to end power because our dies off after 70mph.

 

What's all done to your rdx? Not sure where 70mph comes from. I feel a k03 would be a downgrade seeing full bolt on 1.8t vw's barely making 250hp on them. I'd look into the blouch upgrade that TheWrench has done. Info in posted a couple threads down. Swapping to a k03 would involve a new manifold and downpipe. More work and money than little gains if any.

 

Stock turbo I'd td04hl bigger than ko3 . that be a down grade .
