Just bought a tidy bm 320i, only 2 owners from new and 77k but the engine was ran low on oil and now knocks its ass off, how difficult would it be to drop a 325 lump or evn if possible an old 730 lump if it'l fit?!?!?!!?
Any help appreciated

325i pops right in, the M30 too but you need to fabricate your own engine mounts and depending on how you mount it the rad fan has to go (replace with an electronic one in front of the rad). Some other little trivial things too like the dash, OBC, etc.
For both you'd ofcourse need the correct ECU, injectors, intake, etc.
I'd go for the 325i lump btw. Unless you start some serious tuning, performance will be similar, but much better MPG and less headaches getting it in.
But actually, everything seems to fit in there, there are even some crazy Germans running with 850 or 750 V12 E30s.
