can gains be seen with an evo 8 16g turbo swap. How hard is the swa. Any info is needed on swap

 

I'm gonna go ahead and guess that it doesn't fit.

 

you can use the turbo but not that from the evo. There are companies that make it fit your car.

 

yeah but what companies make the kit to do it?

 

Forced Performance and Deadbolt both offer a 16g turbo for the Impreza. You won't see really any benefits with a 16g on an STi. You have to go with at least an 18g with an upgraded turbine housing before you will see any signifigant power gains.
