Good day on all sides ! Before ….yes , I’ve already used the SuFu extensively ; either I can not find the right search terms , or on the subject there is hardly anything 😉 I want to replace the engine for covert reasons , my information is up to date , if I take a B 235 E engine until MY 2002 , then this is easily possible . Because I have turbo and cobra pipe from the R …. I can do without the sodium-filled valves . Alternatively it seems easier , B 235 R from 2002 to 2004 to find ; these differ according to my information only by the hole in the engine block for the new PCV. Can the conversion into the car from 2001 ….would be only an advantage, because of the lower oil consumption. Has someone already done this, or closer information about it? Gruss Artarun
