I’m pretty sure n20 has aluminum oil filter housing just like the n52, b48 actually has plastic oil filter housing. I haven’t heard of too many turbo problems either, unless of course the stock turbo is asked to do too much. Tstats do seem to not last long in many turbo bmw engines, but I haven’t heard about the n20 in this regard too much either. As for the injectors, these are not like n54, and there’s only 4 of them. If they are an issue. I would not mind an n20/n26 as a daily, the latter has a lot of the stuff covered under Sulev warranty if you are in a Carb state. What’s the point of going with b48 if still needs to have timing chain replaced and now it’s in the back? I could understand b58 but b48 would be a pass.
