325i aint the same block, the 328 is a M52 engine and the 325 is a M50
the 325 dont have the niklsil issues either
mines done 150k miles and to say it gets driven hard is a understatment to say the least,,,,, its never missed a beat but its not that quick but it still sits are 130 easy and gets there in quick enough time but from 135 to 150 takes a little longer than it should
my 325i is the best car i bought imo,,,,, i don t mind the engine letting go as i wanna do a cossie conversion on it,,,,, but it dont seem to die
