I have hard rods. (insert inappropriate joke here...sorry had to). They are Manley and turbo tuff!!!
I think what a lot of people forget about building up a Subaru is that..yes it is factory boosted...but only to 305 crank HP max. When you start talking about 400+ whp, that is a HUGE percentage increase. It is no different in any other tuning platform that is factory boosted when you start talking about percentage increase (except for maybe the EVO but it runs into other issues at that percentage).
I have heard of some stage 2 level cars (specifically 08 STI's) that have had issues, but for the most part that is rare.
I would post a picture of my car...but it is back in the shop again. BUT...there is a surprise when it gets out.
