The Steptronic in the '08-'10 135s were made by ZF. That transmission was good for an automatic. However, the Steptronic in 128s are made by GM. It's a completely different unit and not quite as good.

The DCT in the 135 is obviously a whole different issue, that's a great transmission.

As far as engine mods, being an NA motor, you're right, there isn't much. BMW Performance intake and exhaust is all I can think of, but I don't have a 128 so I don't know much about them. I know there are companies which offer stroker kits, but are very expensive.

The 135 on the other hand, is highly underrated in terms of power. Stock cars are dynoing at 290hp to wheels with right around 300lb ft torque with the N55 motors. With nothing but a ~500$ tune, 2 of which have just been announced by 2 top companies, you're looking at 340-350 wheel horse power and even more torque.

It doesn't make much sense to mod a 128i for power. You will spend more money and make less power than a stock 135i.
