156 vs 75 than 156 vs 75 vs 155
I suspect the 75 is a 3.0 and the 155 a Q4. Mats, am I wrong on this?

156 vs 164. VERY FAST 164, smokes the 156 excepts for the slowest turns

Great videos!

Correct, the 75 is a 3.0 v6 and the 155 Q4.

The 164 has a inline 4 from the first model year 164 turbo, ran good while it lasted. I heard it threw a rod at Anderstorp.
