Sup all,

i'm from South Africa , and we get the german spec M3 here, i would like to enquire if the cams will fit my car, if they are the same as the US spec cams, and also which m3 model cams do i use , the 3l or the 3.2l??

any info on this topic will be much appreciated

thanks

I wouldn't bother swapping the cams on your turbo car. There is a turbo 3.2 liter Z3 with 328 cylinder head/cams making around 540 rwhp. The car was originally a 2.8 liter, so he kept the head and swapped the block...but clearly the cams are good enough.

328 cams have 9 mm, 9 mm life and 228, 228 deg duration intake/exhaust respectivly while the 3.2 cams have 10.2/10.2 mm lift and 252/244 deg duration. The #s look good...i'm about to do this to my car while i have the head off for headgasket, i'll let you know how it goes.

Got the head back on tonight, the car FELT like it had a lot more power after 4.5k than before, but i'm im lower compression and the same boost/ignition so it should have auctually LOST power, it did FEEL faster than before tho. I'll try to get it on the dyno this weekend and compare #s.
