kerrynzl 3 Report post Posted August 30, 2006 M52 are usually alloy block [except USA & SA models] S52 is a 3.2l M3 version of the USA M52 [uSA M3 that is, not the Euro M3 which is totally different] Quote Share this post Link to post Share on other sites

westy 614 Report post Posted August 31, 2006 (edited) You can run an EWS(OBDII) engine with a nonEWS(OBDI)comp if you convert the intake/sensors.Ie m50 intake manifold ,engine loom etc. The s52 cams are interchangable with the m52 (&m50 I beleive)cams(nice upgrade)so I dont beleive the s52 is dual vanos. Dont forget the s52 is north Americam market only. No such thing as a Euro s52. The m52TU is dual vanos and electronic throtle body(e46).

petone 0 Report post Posted September 11, 2006 S50 is 3L (US Market) S52 is 3.2L pretty sure S50 is OBD1 while S52 is OBD2 S52 is basically a bigger M52 with hotter cams and maybe a few other bits. Quote Share this post Link to post Share on other sites
