: What is meant by more "radical" engine???? I have heard that the 95M3's are faster and handle better than the 96-98M3's. Any truth to this?

Well, according to what experts have told me, the '95 engine has slightly wilder camshafts, and the intake manifold is much larger (hence us 3.2 owners get screwed on that). This is so the torque is increased, but also at a much lower RPM, for the 3.2 (the way the american market likes it, good city driving). But the 3.0 makes similar HP, off lesser displacement, so you have torque that comes much later, and is less (but much more usable on a track since it's like past 5200rpm for max torque-you are always using it). The 3.2, at 3800 rpm makes max torque, which means you really only use it in 1st gear during performance driving, after that you are shifting into like 4500-5000 revs for the next gear, and torque is already dropping. Basically if we were still OBD I and we could put the 3.0 intake manifold and cams onto 3.2, we would see more of an improvement expected from the extra almost 200cc.
As far as which one is quicker, well the 3.2, out of the whole, easy. 1st off lots of people disagree, but I have yet to lose to a 3.0 off the line(and I have driven the 3.0), and logically speaking, the 3.2 makes more torque, and sooner, has same HP, and it has lower gearing (3.23 vs 3.15 for '95s). So in accelaration, the 3,2 would win right from 1st gear, only problem is I think it would lose on a track. I have also, like yourself, heard that 95's are supposed to handle better. I have yet to see that in the mags, but I really don't have much to say about that, don't know. My exp in a 95 was that it was "fast" (like on freeway and out of turns), but not "quick" (straight line accel, out of hole). Hoped this helped. PM3

I know you know most of this stuff, but I tried to put everything together the best of my ability, to make sense out of it. Sorry so long.
