So I have a lightly modded 06 sti, spt cold Air Intake, spt Exaughst, stage 2 clutch, lightened Flywheel, Cobb downpipe. Still have VF-39 turbo and stock top mounted intercooler. I was looking at some Mishimoto top mounted Intercoolers and was wondering if that was a good idea as next upgrade? I was also wondering if I should keep the stock blow off valve or upgrade to maybe something like a Perrin or HKS blow off? As far as how I drive it’s more of a drive it on the weekends kind of car but when I drive I want some power behind it, like everyone else, but I never run it crazy hard or rev it uncontrollably so it runs great. I’m running around 18-20 psi of boost.
