As people have stated; Honda has really dove into making turbo cars cause in most cases Honda makes economy cars. Turbos can in the wrong hands make a car really less reliable and cost more to insure and repair.

With Honda's sucess in making high hp cars especially with the S2000, 1999-2000 Honda Civic Si, RSX-S, NSX, and other cars making well over 100hp/liter why would they want to go that way?

Insurance is another reason why Honda does incorporate turbos into their cars.

Then you also make the car heavier too.
