Yes it makes more power because it's the 333 hp motor, they were available in the E36 bodies in europe with a 6spd or SMG. They basically shipped that motor (i'm not sure the code) over to the US and put them in the E46's. My uncle was telling me this a year before the E46 came out, he wanted to do the euro 333 hp motor swap into his 99
Incorrect the E36 m3 euro engine is S52 the current E46 M3 engine is S54.
they are two different engines. Block is different, the S52 has itb but two tbs are tied together. S54 has true ITB.
S52 Euro = 333bhp
S54 euro = 343bhp (333hp in the us).
So your uncle is misinformed. Also the euro swap is not as fast as the S/C that he did.
