Does anyone knows how many 155 GTA were produced back in '92.
I want to know only the GTA - not the 155 V6 TI that raced and the German championship with the V6 engine for the '93 season.

I'm trying to find some notes I used to have and I can not.

If I remember well, there were only 4 cars produced?
Is it true that the engine head was rotated by 180 degrees and the inlet manifold was towards the front of the car?
Is it true that the engine block was not the same as on the Q4? Was this engine more 'square'?

I do remember it had 400 bhp at 6000 rpm and that the gearbox was 6-speed sequential. There was just a button to engage the reverse gear. F1 derivation brakes ...
