Anybody have a T4 flange/Turbo laying around that they can measure the circumference of the rectangular inlet on the turbo please? Starting mockup stage for Front mount now, and need to see what size piping to use after the "Y". 2.5" might be a tad small compared to flange, but thats what I want to check. I'm sure 3.0 is going to be too big and hurt velocity.
Circumference of 2.5" = 7.85
Circumference of 2.75" = 8.63
Circumference of 3.0" = 9.42
Circumference of 2.5" = 7.85
