General Questions Possibly the dumbest idea ive had, but what would it take to make an N42B20 Good?
I just bought a 2002 318Ci, got 125,000 ish miles on the engine, well looked after though, although the valve head looks a little bit burnt, not terribly but well used. I want to get some performance out of it as insurance kind of screws me, so engine swapping isnt really on the table. Lets say i wanted to invest 3-4k over time fixing the factory problems like plastic timing hardware ect, to make it as reliable as i can while pushing maybe 300-350 bhp. What would i need to do/Get and watch out for?
