As for yourself Steve, if you can, spend some time in that forum I've been going to lately (my links from previous posts) originally put up by Ian (Imay) it's very informative on BMW's especially the 1 series and the 'N54' IL6 TT engine we're talking about here...
It's even answered all my questions I originally asked you about the 6sp steptronic trans
BTW the power output is alot more (as I'm sure you know) than 30kw over the 128i's N/A motor (the average dyno readouts I've seen show 191kw at the wheels for an auto equipped 'N54' engine powered Beemer) and the torque is also much more than quoted and around 50% more than the 128i's N/A motor...that's a HUGE difference - Ian this is a good point for you to know too !!!
The 'N54' engine is also running a very conservative tune, as with most factory turbo engines...flash tunes with no other mods give increases of around 30% in both power and torque and exhaust/induction mods give up to 50% increases if you wanted to go that way, so those tiny Mitsubishi turbos are nice units Steve with plenty extra potential on offer
Just for info the N/A 3.0ltr IL6 in the 125i is rated at 160kw with 270nm at the engine...
