Hi, I am new to this forum. I have just purchased a 1989 E30 320i and was wondering if it's possible to get the crank, pistons and rods from a 325 and replace them with my ones. Obviously the block would need to be bored to 84mm to match and probably the head off a 325 as well due to the larger valves. But is it possible to use this as a stroker kit as the engines are pretty much the same?

Cheers for any help

So you want to change your B20 into a B25/7? As dabs said, Get yourself an entire lump and drop it in. Much cheaper and less work.

Many people have dropped an M52 into my E28 so I wonder if its worth doing it to an E30. A Vanos system does sound nice.....

      Resonator assembly clip

      I am new to site and just bought a used 2017 330i xdrive. I was going through the engine trying to get to know it a little and I found a resonator assembly clip sitting near the resonator but connected to nothing so I’m trying to figure out where it goes? There is already one connected to the intake tubes so I can’t figure out where it went or where it goes? 13-71-8-637-816 - Resonator Assembly Clip 2017-2023 BMW | Braman BMW & MINI Parts.pdf

      04 525d

      Hi all, I have an 04 525d that I’m looking to get rid of. It has been well used and served me well but unfortunately I’m not willing to spend any more on it due to the age. It has 185,000 on the clock and recently failed it’s MOT due to perished ball joints. my question is, is it worth trying to mess about and sell it or just scrap it? any advice would be greatly appreciated. cheers

      Coolant leak

      Morning Kev Welcome to the Forum I am aware that the plastic return pipe (Header Tank to Rad) on the E53 became very brittle and was easily damaged. I replaced mine with 10mm Copper Tube after a long wait for replacement. But I was not aware, or haven't heard of X3 issues here in the UK I guess that you will need more from US based owners Dave
