bought the 2017 hr-v , and pleased with my purchase , my wife though misses the extra oomph that the turbo gave on the previous  car.  We do  not like much the hrv sport , and as a long shot what would the fitting of a turbo to our car cost, and is it a viable proposition. Anybody got an opinion on this>?.

Hi Pete.....welcome to the Club

It would not be a viable option unfortunately as would be cost prohibitive and also a lot of bespoke work to adapt the engine to run with a turbo.

A better option would be to have a 'remap' which works with the Engine control unit to release more power.

Very simple and cheap option but with a noticeable outcome
