s38 transplant
I have a very basic 89 520i originally imported from germany and i've had it for 6 years. I am currently looking at transplanting an s38 3.8l motor into my baby. A contact of mine says he has already found a possible source for the powerplant i wanted and will keep me posted as he scouts for more possible sources.
My question is how difficult could the swap be? Honestly? What I love about my car is its simplicity. My car has very very few electronics as compared to the higher end e34 models and i'd like to keep it that way. Now:
1. If the electronics of the donor car is bad, is it possible to run the engine with a non-standard ecu? I know motec is expensive but will this work? what other options do I have?
2. Would the use of tripple side draft webbers work? i'll have to sort out the ignition part with Electromotive ignition to run with the crank sensor.
3. If the original ecu and harness is still good, is it possible to simplify the system and get rid of all other electronics such as the check control module? Again, this is just to make it as simple as possible.
I know i'll have to upgrade the brakes and suspension as well. That part is quite straight forward. what worries me is really all the essential electronic stuff that comes with the engine.
Please help...
