This is a KO4 turbo. It’s a upgrade stock style replacement for a KO3 on a new beetle 1.8T. I just started last night, but it was raining. So maybe I’ll get to test it today. I drove it with a T3 turbo and it was making minimum boost, so I went to this smaller turbo. It’s only a crammed 1600. It was easy to build from scratch with the T3. Flanges are cheap and other parts are readily available. The KO4 was more of a challenge. Especially since everything was all set up for the physically larger turbo. It better make boost now.
