So I was scrolling through the internet and I found an hx35super. I never heard of one. How well would this be on a 4bt. It's supposedly has a 8cm exhaust housing. https://www.ebay.com/i/292033711652...3D711-117182-37290-0%26rvr_id%3D1233372588100
A tighter turbine is only half the issue. The HX35 compressor is too big so runs low boost and poor efficiency at 4BT airflow.But that's not a normal hx35. It's a 54/55/8. I'm using a 44mm hx30 now it's a good turbo. But I never seen that hx35 before.
