You keep....saying how it's the same part numbers. But then you say yes it has a dry sump oil system, also stronger syncro's oo by the way a lighter flywheel and they are the same it what kind of way man.....your naming off very important details which in turn make it much stronger and better for spirited driving. What I'm trying to say is straight run my brother's 1m yes it's quicker then a stock 135i 6mt but not night and day. So what I think is transmission wise they should have done whatever multiple changes they made to the 1m also to the 135i. Since the overall power is very comparable.
. Just my input.
