That's a nice clean install. I wouldn't worry too much on the T4 78mm exhaust wheel. It's a little on the small side for 380" motor, but for a street car it'll spool really nice.
Mine is 367" with an T6 88mm exhaust wheel, and it's pretty laggy. So you made a good choice for a street car.
Thanks, what size pipes do you run on your hot side? I know it’s a totally different combo and type of build, but your ET and MPH are certainly inspiring for an aspiring turbo guy like me!
