Vf52 re working
 

In the mazdaspeed 6 community there was a shop in Florida that would take our k04 and port and polish them and give some impressive gains before you had to swap turbos for more power. Is there anything like that in the subie community especially for the vf52's?

There is, but for what it costs to get done you can spend a little more and get a brand new turbo with a warranty.

So the gains aren't that great for the vf series? I thought prices ranged around 500 I do t think there's a new turbo for that cheap with warranty without something being wrong with it

Thanks for the link mike. Interesting read!
