ok i have a RB20 TO3 which i was told is to small for my RB30/25det now i have been told i can hi flow it or hybrid it or just buy a bigger turbo. i want to know wat i can do and for how much am i looking at i have been pricing bigger turbos i am just worried about manifolds as i was told the the T60 will fit on the RB20 manifold but might need a spacer and oil and water lines and external gate. I want to keep the manifold and oil and water lines cause i have a very limited amount of funds at the moment. now hyriding my T03 wat can i get it hybrided with and wat boost can it handle and how much am i looking at. also i heard that the waste gate in the to3 has problem holding the boost wen hybrided with a TO4 so i have heard is this true??? if so how can i over come it.

My RB20 hiflow turbo made 240 Kw @ wheels on 16psi when bolted on a RB30/25 twincam. Excellent boost low in the revs, full bost by 2500 RPM.
