Can I put a 91 M119 in a 88 124 that had a m103?????

[johnflight1]

I found a 91 m119 eng and was wondering what it would take to put it in a 300E? My major concern is the electrical part of it. The m119 looks like it has the same type of injector system as my m103 individual lines from a distributor going to injectors, no fuel rail, no electric going to injectors.
My 300E is an 88. We have a highly skilled team of commercial aircraft technicians. we love doing stuff like this just for fun. We have a fully equipped shop with lifts and stuff,but if the computer part of it will not work without very excessive costs then I am not willing to do it because the car is only Worth about $2k.
we just want a fun project!!!
will the 1988 722 trans bolt up,along with the downshift cable?
what computers should I rob out of the donor car?
will we need a different wire harness?
what year did Benz start putting the V8 in a 124?
Thanx in advance for any sugestions John
