Series 1 M62


Series 2 GenIII M90


Series 3 GenV M90


And yeah, use the search...or hell, even google. There are tons of write-ups swapping on the GenV blower.

Do you know it is more efficient?

Do you know you can't pulley drop like the GenIII without more valvetrain or flow mods?

Do you have headers now?

If not, the GenV isn't gonna be worth it TBH.
