auction is for a lower block with crank ,conrods ,pistons ,and ali block from a M54B30 engine like in a e46 330i e39 530i e38 730i X5 3L 6cyl etc .

people use these cranks and other parts etc to stroke a smaller capacity engine like a e30 320i 325i , e36 323i 325i 328i e34 525i ,e39 523i 528i e38 728i etc etc . M20 , M50 ,M52 type blocks , plenty of info if you google M54 3L crank into M20 , m50 or M52 etc

makes easy horsepower . lighter conrods and pistons than other older bmw engines

have heard of results like 160Kw at the wheels about the same as you get from a 3L m3 engine in a e36 M3.

auction is for the ali block , crank shaft , pistons , conrods etc.

if you have a later M54 engine dual vanos e46 323i 325i 328i or e39 523i 525i 528i e38 728i you can just put you head on this block and away you go with a 3L engine .

or use the crank rods and pistons and fit them into a m50 or m52 block like in a e34 525i e36 323i 325i 328i , e39 523i 528i etc .

or use the same set up into older M20 engined car like e30 325i 325e e28 525e to make it a 3L or larger depending on what pistons you use etc.
