Is the best diagram I have yet found on these turbos.. although it could be totally wrong.
If i'm aiming for 250rwkw with the potential to hit 300, surely the 25G is the better option?
Or the 20G if I go for a TD06H?
Sorry to be a pain in the balls, there are just way too many options with stuff and i'm a total noob .
