A mate of a mate did this for me. It's one of many pages. In short everything mechanical is Gemballa engine,gearbox,brakes,suspension you name it and it has Gamballa written on it.
Engine is still 3.2 but it has turbo heads,cylinders,rods,pistons,crank with a reinforced block and crank bearings. I've only had a quick look at the heads and you can see the Porsche "turbo" script cast into them.
