Hello,
I have a problem with the engine of my Mazda 6 MPS (22/12/2005) 2.3 Turbo 260 HP. The engine needs to be repaired completely (Major engine repair). The problem is mainly connected to the crankshaft and the crankshaft bearings. I am asking for advice about the engine repair. Is the engine hard to be repaired compared to the engine of Mazda 6 2.3i - 166 HP?

 

Your engine should be relatively similar to the normally aspirated engine, if you have the skills to overhaul one, you can do the other.
