Anyone a advice where i can get either a new or used kit??

I anyone can share with me the wiring diagram for the ECU?

But for 4K - 5K plus installation you would be better off getting a 5.3 and dumping into your H3. You can probably get a crate motor for much less.

 

Don't do it would be my advise. 08JJ has a very good point, but that isn't the only reason.
