It's been a couple years and my BMW trivia and knowledge is a little rusty so I am going to need some help here! How much did the M3 change power wise or anything else from '95-'99? It seems like I remember in the earlier years the hp rating being a tad lower but I could be wrong. Any other changes would be appreciated too. I am trying to determine what would be the best year(s) to look for. Thanks!

OBD2 and OBD1 have the same horsepower at 240 crank power. In the obd2 cars (96-99 us spec) the cars torque increased from 225 to 236 lb-ft. As previously stated it is partially easier to upgrade the 95 M3 obd1 s50b30 motor. Going witht he 95 leaves the great option of witching to bigger injectors, 3.5" HF and 3.5" cold ir intake for a huge gain of almost 25-30 horsepower and similar torque gains. Going forced induction isnt necessarily a problem because kis have been well deigned adn developed for both obd1 and obd2.
Go with acar which you find is in better condition and lower mileage....and if you're lucky, no sunroof.
95s had a slightly mroe agressive suspension setup with unstaggered wheels/tires and more negative camber. Stock versus stock the 95s are mroe nuetral when compared to the 96+ cars which are more built for understeer. This can easily be corrected by swapping out a few items.
