Opel Omega 2.0i 16v Edt100.

I want to know more things about this car.
On the waranty book is writed 185 hp but the omega 2.0 has onli 136 hp.
Is there an error or the engine is turbo charged?

It's an error, there was only one 2.0 16v on the Oméga which makes 136hp. Now, it has been replaced by a 2.2. ;)
