What is the stock horsepower on a 1988 Porsche 944 non-turbo?

Websites usually only give the turbo model or S model hp rating. I am looking to turn a non-turbo porsche into a track car and i want to know its stock hp.|||The base 944 model used the 8v 2.5L engine and produced 158hp.|||The na is 147-157 stock. With its light weight and gear ratio most people in my car think it has a v8.. Due to its high compression there is not much you can do to increase horsepower....A cold air intake is about all you can do for an extra 10hp... It already has a great exhaust system....|||185 HP
