It’s no secret that we at TopSpeed are huge fans of the DOM 1.5 and stock location setups on Subaru’s because, for the most part, they fit the customers goals and work great for the intended use. This thread is for a car that throws all of that out the window. This customer is a local and has gone through several different setups, including a DOM 1.5 that made great power… that wasn’t enough for this guy (in a good way ). He had goals of truly taking his car to the next level and wanted something he could have tons of fun with on the street and at an occasional drag racing event or dyno day. His goal: 500 awhp on pump and see what it makes on VP C85. After going through a few different turbo choices, we settled on the GTX3582R. Normally we would recommend against the GTX line of turbos for Subaru’s as they do spool slightly later but since this car was going to be tuned on C85 the spool times would be very close and the GTX would flow much more up top. This build was a ton of fun to complete and is even more of a blast to drive!
