If he tuned his Mk4 2.0 non turbo with a turbo it will be an over 200 bhp car, so what do you think?

Question

the new mk5 golf is 190 bhp and be recognized that we are talking about a four cylinder engine.

Answer 1

This question isn't making a lot of sense right here....

200hp isn't a lot lol

Answer 2

200bhp is easy! just replace your manifold and air filter (i suggest a cold intake system from K&N or Simota)

you will get around 30% more horsepower

I suggest that you find a reputable shop with a dyno tester so that you can see the actual improvements on the modifications that you will do to your car.

aftert improving the way your car breathes, I suggest you do the necessary changes to your brakes before you do additional improvements on the engine (like adding a turbo)
