I have a much loved completely unmodified 02 WRX with 175K miles since almost new. I dont drive it too hard.
(I am probably not a typical WRX driver, and not a 'car guy' - I can find the hood release, that is about it..)
Regularly and fully serviced, zero issues until now,
Still sounds/runs/idles fine, gas mileage still good.
Last service our (excellent) local service repair shop pointed out turbo was kicking it late (4200rpm) and not working well.
I trust these guys 100% as does most of the local neighborhood. I asked them to fix it..
They checked everything decided it had to be the turbo and sent off to be refurbished
It was a turbo problem, so the refirb shop said, and final bill was $1300 which I thought sounded very reasonable ?
Turbo now kicks at3500 rpm but just does not to me feel like it has the power it used to..
The kick in the back is more of shove...
Garage looked again at length, said everything seems fine, ECU happy, all they could find was a very dirty mass air sensor.. (which means nothing to me..)
They know I am not happy and are not charging me for last check (which I feel bad about)
I get the feeling they are not 'turbo experts..' if there is such a thing ?
any ideas ?
-At 175K should I expect it to be losing some power ?
Do I have to take it our local Subaru garage (that I DO NOT like/trust. - don't get me started...)
Can anyone tell me a good simple test to see if engine giving OK power ?
ie. 2nd gear stopwatch time from 3500-6000rpm ?
Do I need to buy and fit a boost gauge ?
Really Appreciate any pointers. was planning on keeping this car until one of us stop working..
