do you mean the M6x engines? if so there is no such thing as a 4.5L.

the M60B40 came in the E34, a 4.0L V8
the M62B44 came in the E39, a 4.4L V8

They did make the 4.5, however it's discontinued. If you're gonna go with a v8 4.0 is the way to go.I've heard that the 4.4s have a problem with the timing chains. Are you wanting to put in the touring you've got listed? If not,why not just get a 540? It would be a whole lot easier.

thanks for the input. i am not going to put it in my 525i i am going to hopefully get a project car that is in good shape bodywise with no transmission and/or engine and put a 5 speed and rebuilt v8 (probably a 4.0) with a turbo or two

i tried and didnt come up with any results. thats why i was looking for verifiication. i think you must be thinking of the M62B46? or maybe you are talking about a later V8 like the N62 which i dont know about.

just because someone says in the post its a 4.5 doesn't mean its right. thats an N62 engine which is only available as a 3.6, a 4.0, a 4.4 and a 4.8. as far as i know, bmw have never made a 4.5L V8

So it's a 4.4valvetronic....but they called it a 4.5 http://www.bimmerfest.com/forums/showthread.php?t=24577
