What exactly are the differences between our beefed up N55s and 335i's and 435's?

Obviously BMW advertises the M235i with 20 more HP and 30 more TQ. But I read some vague information regarding our forged crankshaft and dual oil cooler setup? Compared to F3X N55 models having cast and single respectively.

It would be awesome if some light could be shed on this

As far as I knew they were the same, but the 235 comes stock with the ppk tune. I could be wrong though

This.

The oil cooler setup is standard on the M235i, whereas on the 335i you needed to order the Msport package to get it.

So we do have 2 oil coolers?

And what about the forged crankshaft? Does a 335i M sport have the same part?

Yes one on each side where the fog lights would be

No, not in the way that's implied by the way you're asking.

There are 2 coolers that process oils, just not the same oil, and both on the right. One is the engine oil cooler, visible through the lower vent in the bumper, where the passenger's side fog would be if we had fog lights. The second is the transmission oil cooler, also on the passenger's side, located above and behind the engine oil cooler inside the engine bay, up towards the hood.

The second radiator visible through the lower bumper opening on the driver's side where a fog would be is an additional engine coolant radiator, not an oil cooler.
