What's the Difference?

Hello,

I am trying to find out the difference between the 2 of the N52B30 engines found on 128i and 130i.

I hope there are some mechanics out there to shed some light on this. Same engine but 2 very difference outputs.

On 128i: 230 hp (172 kW) @ 6500 rpm and 200 ft·lbf (271 Nm) @ 2750 rpm
vs
On 130i: 265 PS,262 hp (195 kW) @ 6650 rpm and 315 Nm @ 2750 rpm

Thanks!

USA smog control, and could be some different tuning. Different power bands for US vs. Euro drivers.

Not sure about specific parts though, as I am not a mechanic.

I think it's the more advanced 3 stage intake, and also, it's the fact that the US is a weird market and BMW is too afraid to have a car too close in performance to the 135i for a much lower price, hence why we only have two models, 128 and 135, vs europe- 116, 118, 120, 123, 125, 130, 135.... did I miss any? As far as emissions, I'm sure it's just as clean, like the 06 e90 330- had 255hp, and the same engine in the X3 and then the Z4 3.0si both had 265

Makes sense, except that the new Z4 is sold in the US with only the 255 or 300 hp motors... So I don't understand why we don't get a 130i option.
