Hi,

I'm owner bmw e-34 with 2.5 m20 motor. Im also owner crashed e-32 with m70 5.0 V12 motor. I have car service here in Poland with BMW specialization. I did some swaps in my life but i haven't occasion to make my bmw more stronger...
I know its possible to make it, but i know too its real hard, and during this operation can make a place lots of surprises.
I wrote some questions on Polish forums, but propably noone can help me.

Do Somebody here on this forum ever saw bmw e-34 with 5.0 V12 motor?

I need informations which can help me.

I have few technical questions, but i must translate polish words to english to be understanded....

There have been a few, including one for sale recently, complete with a 6 speed transmission. The swap is complicated on quite a few levels, and is not a bolt-in matter.

Yes i know its not so easy, i did some similiar swaps.

I need to know e-34 is enough place in middle tunel to place there automatic transmission 4hp-24 from V12?
I know that drive shaft must be shortend, exhaust system must be remeked..
How about hydraulic brake system?? In my e-34 i have power brake unit depression, i see in e-32 is another system with pressure acumulator. Its not enough place in e-34 with unit depression to place there V12 therefore i must remake a brake system.
As i see engine suspension generally is the same, here shouldnt be problems.
Sterring will be the same, suspension is not serial in my e-34, but it will work.
I know i need totally rebuild electrical system, and it will take lot of time,
how about differential? Anybody knows? Propably it should be changed too....

Anybody knows how to place pics here on my post? I did some of my e-34 and this crashed e-32 with V12. I can post some pics during this long operation from each level...
