This is what I know:
335is (N54)
135is (N55)
Z4 35is (N54) |
The N54 is the earlier more expensive and better tuner motor. This is why enthusiasts everywhere praise it. While many mills are underrated the N54 is prob the most so in recent history. I expect the M4 mill to be pure pleasure as well and underrated as well.
