So, there are different sizes for the hotside of a turbo. The part of the hotside that connects to the uppipe. The two common ones that I see are 8cm and 10cm. What is the size of the stock uppipe and VF-39?
VF39 TB, PZ18 ex.h/47.9mm c.h/9b c.w/0.63 A/R - US MY04-06 2.5L STi
I am finding different answers for how big the stock hotside is. Same goes with the uppipe... The reason I ask is because the hotside on the turbo I have is 10cm. Now, I don't know what that means exactly. What correlation does the size of the hotside make in terms of flow and power?
I'm assuming 10cm is bigger than the stock... What would have to be done to mate up at 10cm hotside to an uppipe (and then headers)? -Can I keep the stock headers and just get a different uppipe? -Do I have to replace the headers and uppipe? Can I PnP the uppipe, headers, or both?
What are options and suggestions for this part?
