Hi
I own a 1.8 20vt Leon with 180hp, k03 turbo.
I thought to upgrade the turbo to K04 and get dyno ecu flash to gain some more hp, what do I need for this build busied the K04?


Thanks

Hi you’ll need all lines for the turbo,manifold downpipe,turbo intake and boost piping to start with.

Your Aux inlet is the other way round then the Bam the k04 came off so you need to figure out how you are going to route the piping. The k04 came with different injectors from the 225bhp 1.8t I looked into it about 10 years ago but with the advances in technology now it’ll be more cost effective to by a hybrid turbo that bolts into your factory location for you can still use your pipe work.
Something like beach buggy turbo k300 is idle if people are still using these I’m not sure as I’ve been out of the 1.8t for years despite still owning one. I’m more focused on the 2.0t now.

The engine model in my car is ary (Leon 4x4).
I heard that k04 with the manifold and inlet should be enough, am I wrong?
Thanks

In that’s case I’m not sure what your car needs I wasn’t aware you had a 4x4 ARY engined car. Sorry. Best of luck
