That right there is a proper build reliable and expensive I myself have spent quite a bit but in the end it will be way worth it… I would rather go with JWT s3 cams but thats me…world would be shit if everyone did the samething… --- _[View the full topic](https://forums.speedlife.net/t/hey-lets-here-your-engine-build/127834)._
