BMW B58 turbo

image Ok here we go again,,,this is a new turbo off the new B58 6 cylinder engine,,,you can see the the new turbo is a different design,,,the exhaust manifold is redesigned with the flexible pipe,,,,the exhaust gasket is now a metal gasket,,,,no more of those round slip on gasket donuts,,,slipping in the metal gasket is easier,,,,and removing the turbo is easy on a 5 series.image The reason for replacing the turbo,,,is customer said check engine light was on,,,,low boost faults,,,found the waste gate lever on the turbo was jamming up,,,,causing a turbo boost problem.image You can see there was a lot of room to remove the turbo from the top of the engine.image Here’s the redesigned catalytic converter,,,this one is more straight and a lot longer then the older ones,,,,also the opening is a lot bigger then the older one.image You can see how big it is,,,,and the exhaust goes straight into the catalytic converter.image Here another thing about this new b58 engine,,,we have new ignition coils,,,we went to one that look like Honda or Toyota type ignition coil,,,will see how they last,,,,I hope they are better then the last one we had,,,,,lol

    • Lol,,,Good luck on that,,,,I think the problem is the design,,,,the coils get so hot sitting inside the valve cover,,,,the new ignition coils have a metal sleeve around them for the heat
