I think strengthened pistons and block aswell as updated cooling system with 2 coolant tanks. The A variant has only 1 tank so you can differentiate them easily like this

Remap the 320 or 330 and you will get up to 300hp if you have the b48b20B. If you have b48b20A it will only handle about 250. 330i are all stronger B variants but 320i has both A and B variants so you will need to check. It’s a very healthy amount of power for a car this size and will sip on gas. Also, they can handle a little better than the 40i since there’s less weight over the front axle.

It’s not a very fun engine as all the power is in mid-range but this makes it perfect for a daily as it’s so easy to drive, you can keep up with traffic with just the lightest touch on the throttle. There is lots of torque and it pulls hard at all speeds, it’s amazing how the speedometer moves so consistently up to around 200kph and then keep going to a top speed of over 160mph in my Mini Cooper s, this thing in a 3 series or larger will eat autobahns all day long.
