Engine Modifications
Alright my name's Ben and I'm new here so cut me some slack with this. I have a 2004 wrx, not an sti, and I am trying to do a turbo upgrade. I have been looking at a vf39 or a vf48(that's the 2018+ sti turbo correct me if I'm wrong). I am wondering which I should go for. Or if I should just save...
