hello !
any of you guys did a conversion from an M43 to an M44 ?
whats to change?
the clutch and gearbox are the same, ignition same , even the waterpump is the same ...
how about of the Oxygen sensor and the CAT ?
and of course the ECU needs to be changed along with the MAF ...
but what about other sensor or wiring related to electronics on-board ?
Please help !
Thanks u guys !

not really sure, since the M42 car i bought had a blown engine. my coworker (bmw technician who used to have an M42) said it pulled a lot harder than his car did. was a faily simple swap.

btw my motor was from a z3 1.9L
