Howdy yall, I drove a friends MK3 a few years ago and instead of blowing the excess off in to the air it re-injected the pressure back in to the turbo. What is this called and where can I find one? It made the coolest sound and kept the t66 spooling quickly.
Thanks

its a diverter valve. they are stock on supra turbos. some aftermarket units come with the tube for it to be re-dumped into the intake.
