So im doing an M52b25 engine swap, but am going to try and use my existing manual gearbox from the 318is, was working well before i removed the motor. I understand its not the best for the task and will most likely fail at some point. But im keen to get the car running and driving and need to save some extra cash for a 325i gearbox. Going to replace the clutch on my existing 318is box and wondering if an OEM clutch/flywheel from a 325i and 318is are the same. Done a little bit of digging and part numbers are different but they look identical on images. Can anyone confirm this. I would rather be able to buy a 325i clutch and flywheel so i can swap it over when i get the new trans.
