The 2.5Si and 3.0Si are pretty much the same engine.
They use Valvetronic and valve lift to throttle the engine and so shape the torque curve.
From what I've read there are tuners now offering packages for the 2.5Si that basically give them the 3.0Si valve lift range and so bring their power and torque very close or the same as the 3.0Si engine.

Have been considering these to be honest as they seem to offer many benefits strong performance usable torque & very good economy, having now sold my M3 which I owned when I first posted on this thread I can agree that the 3.0 straight six in my 330i isn't that impressive in terms of performance but I blame the weight of the 3 series for that but I do love the N52 engine very much as its silky smooth & very free revving & although its not very vocal the sound it makes is very pleasant & it has what I describe as usable power.Ooch said:I suppose If you wanna go fast these days get a diesel Barge....
