Tristram came to us awhile ago with his beautiful late model e30 sedan(love the blue), we did a 5stud conversion (2019), later returning for long term Conversion (2020),unfortunately came at the wrong time, but with a very understanding owner!, We took on and started his m54 conversion, the unfortunate part? by the time came back our shop was moving towards a “Bosch Service Centre”  so the strip and paint shop ,refit to suit the Bosch dealership , along with some health issues! ….Next hurdle one mechanic down we are into a very slow conversion! With m40 4 banger out and m54 in on its mounts we are hit with a major health problem that stops everything,  not helping was another e30 conversion holding us up with S50B32 Engine ECU and supplied engine failure …with other exrtas added along the way.…All that not a fulltime issue now, we are as of  late-March 2021 finally onto this one !
