its that i dont know how z4s only have 225 and thier like 3.0s and m3s are like 3.2s and there makeing 333 hpwhy cant the z have at least 300? the motor cant be that diffrent frm the m, i mean is it even worth putting money into a z4? suaks theres way more parts for m3s and stuff then for z4s. i guess ill leave mine stock for now, i have a color which is pretty rare ( urban green) guess ill wait till the z4m comes out. :(

umm is this a serious post?
the m54 & s54 are very different engines

if you havn't noticed, generally only the m cars recieve engines with the s designation

the z4 has [had] the same engine that the 3er, 5er, x3, & x5 have/had

:buttrock ? why did you even buy a z4 if you are planning on getting a z4m? you are waiting money you should have just waited or just got an M3 to begin with.my car is fast as hell just buy you a supercharger and some other things and its kickass

jeep how much hp does ur z4 have? and wut cars have u taken with it.

i had no choice it was ethier a z4 or i had to wait 2 months to get an m3, plus school was starting and i wanted a new car. i said screw it ill get the z now
