Here's is what I measured before from my build , see link

" Been doing some testing with the front mount box car . Must say the gearbox feels excellent and somewhat foreign . I was trying to work out the balance of the car on paper. Here some weights of the changed parts .
119 diff and tube complete in rear - 57 kg ( damn heavy )
Vs
116 gearbox plus clutch in rear - 62 kg
Therefore lighter 5 kg in rear plus I have moved battery from passenger side to rear in my original race set up ( 14kg) so net result is 9kg heavier .

BMW gearbox bolted up front plus clutch - 46 kg ( but its mounting are in line with old gear lever plus shared to engine mounts)
Overall car is heavier by 41kg . "

By the way do you have any pics of your mechanics car with the Sei diff in it ?
There was a chap selling a complete Sei here in Uk a while back if you're interested . I know he was scrapping it . Then its even easier for conversion as you then cut the diff mounting bracket from car and you have brakes and drive shafts .
