Hello, i'm new to these forums,
i have just got a 2009 Mazda 6 125BHP, im just looking to know the difference between my 2.2 125BHP and the rest of the more powerful 2.2l diesels,
as far as im aware, it might be injectors, fuel pump, boost, intercooler, or is it just a case of playing with the wastegate to get towards the 185BHP version?

any help at all would be very much appreciated, ive already searched for this, both here and googled the life out of it!!

thanks, michael.

 

Bump! any help at all?

 

As far as i know the 3 diesel power versions (low mid and high) is identical. Even the cars (brakes, gearbox) are identical. The difference is only a "chip" controlling engine performance.
