You can use either motor, but if you go with the later motor, you will have to change everything on the motor (fuel injectors, etc.) to work with OBD-I.
There is a vague aurticle in Bimmer magazine, I think it was August of 1998, where this type of swap was done (OBD-II motor into 1995 OBD-I ti) UUC Motorworks did the swap, I think. |
