ok, so i got a totaled integra and i'm doin my b18c1 swap in a week or so, and i was wondering how i'm going to prove that the engine isnt stolen when i get emissions in a year or so? What all do i need to prove it's mine?

 

just the paperwork(title and license) on the totaled vehicle. The VIN on that car will match the engine. Just make sure to always keep every receipt and other form of documentation on your vehicles.
