Turbo "fan"
 

Looking to turbo my 2011 Mazda 3, 2.5L with a CARB kit. Any current options? (Some of the older links no longer work - such as F2.)

After some searching this is the only kit i found for the 2.5

I also found this one, you may want to call and see if they can make you a wiring harness for 2.5

That may be your only roadblock on that one.

I did come across some comments that the 2.5L is not usually turbocharged because the internals are not as strong as the 2.3L, being basically a bored out 2.3. The crank is the only forged internal on the 2.5
