That's modified cars for you mate, but then again you have to look at the possitives. You have a 1.6 that has 10bhp more than a stock 2.0 Focus. Sound good to me.
You will be pretty happy with it mate, but otherwise you could try Van Aaken. Their turbo kits aren't the best set ups, but if done right you can see yourself at 160bhp quite happily. But around that kind of power you gotta think about internal parts of the engine too.
