can the n20 be bored and/or stroked to more than 2.0ltrs, say to 2.2? otherwise it seems problematic to exceed by an adequate margin the output of the 135/235 whether it has a further tuned n20(300hp/280ft-lbs) or worse yet an n55(300+hp/300+tq. with additional tuning potential). is half of the m5/m6 engine, in other words a v4 out of the question? i think that giving the 128/228 240hp and 260+tq. and 0-60mph about 5.5-5.7s, set the bar very high to create 2 models above it, particularly if the m2 must have 4cyl. i would have given the 128 a 3cyl w/ 180hp/195ft-lbs., the 135 an n20 w/240-250hp/266ft-lbs. keeping them as light as possible and the m2 a maximally tuned 2.2ltr. n20(or 2.2ltr. v4 if possible) with about 330hp/295-300tq., also as light as possible. of course 3cyl. might not sell in the u.s.
