F32 engine swap with F82
 
I was considering doing an engine swap in my 2014 428i and putting in 2015 m4 (f82) engine, turbo, intercooler, tranny, and gearbox. I'm a noob and not sure if this is a good idea. I'm assuming it would all just fit directly since it's the same series? Any thoughts anyone?

I strongly suspect it would be less expensive to just trade your 428 in for an M3 / M4. These Frankenstein cars never end well, and it's highly unlikely you will be able to unload it when the inevitable problems arise.

No

Beyond the questionable fit of the drivetrain, you'll only get the power of an ///M car and none of the other upgrades which make an M4 a great vehicle. The suspension, body bracing to increase stiffness, brakes, etc would still be missing.

You'd be much better off selling your car and looking for a good, used M4.

:) :D :rofl: :bustingup ... yyyyyeah... No.

Here is the cold, hard fact of engine swaps on modern cars: If you have to go online to ask whether it's a good idea--it's a really, really, really bad idea.

Have you ever swapped an entire drivetrain on a very recent car? I ask because most cars do not have both a tranny and gearbox.

Though on Pride Day, some cars have both gearboxes and "trannies".

Do it with the understanding that you'll likely not be able to resell it as is, or get considerably less for it. The cars are already depreciating like crazy, prepare to get $10k when you plan to sell it.

Thank you for all the answers. The reason I was considering this is because my friend wrecked his m4 and offered me my part or parts I want. He owes me money so offered this instead. But it sounds like a bad idea. I looked up maybe just swapping out the rotors and brake pads on the front and back, but the sizes are different. Does anyone know if it would still fit and work fine? The m4 just has larger rotors and brakes vs the 428i m sports one I have .

Please do not let this "friend" talk you into accepting bits and pieces of the wreckage his car as payment of his debt. Virtually none of the worthwhile parts from his car are interchangeable with yours, including the brakes.

Tell him to sell off the remains of his M4 for parts and pay you what he owes you. :tsk:

Even if the components would fit there is a significant chance of internal damage from stresses related to the accident. Your "friend" is trying to profit from the accident at your expense. Tell him to repay the debt from his auto insurance settlement.
