Never mind, the engine is in position!
I had to cut away a piece from the chassis, because the turbo was hitting the chassis.
And on the passenger side, i used an extra plate of 10 mm, so altogether on that side 30 mm of steel plate.
I have pictures: if someone wants to see them, let me know, but I dont have webspace, or capabilities to put them on the web (I am into cars, not computers)
Now I am gonna build the rest of the stuff: al electronic things, waterhoses, several radiators (intercooler, 2 oilcoolers and the water cooler), gear lever etc.
At last I am gonna fit a differential from a w116 6.9 litres which i just bought.
It's a limited slip, with exact the same ratio as a w124 om603 turbo (where i have my engine and transmission from)
Thanks for your help so far, Jarski!
