you need the 5 bolt turbine housing ,that will bolt to your elbow,if you on a stage 3 t3 your turbine should be a .48 and bolt too the t34

1900 cvh and zvh will work fine on t34 with a .48 turbne my mate run.63 on turbine 1900 cvh 1 bar works fine quick box 130 tops

2000cc cossy standard had a t34 with a .63 housing and was quick enough
so a zvh will have no problem
