Very awesome car, congrats, I myself would love an e36 Motorsport, techno violet for me:thumbs:
Hope she gives you many miles and smiles
I don't want to derail the thread or dirty it, but I personally think swapping to a b28 really isn't an issue, it's plug and play, no funny "converting or conversions" going on, and the engine car from these chassis and models so it still will be like from the factory, especially with gizmo doing it. Also who in there right mind would pick a 323i over a 328i if given the opurtunity? Change the brakes and whatever else and you have a 328i. Done and dusted. I think if it's done well and documented there should be no problem if re sold in the future. Do it! If the difference is like an e46 325i to 330i then it's a no brainer!
Good luck!
I am considering a similar thing with my e34 530i/5 wanting to go to 540i/b40/6.....
