IHI RHB5 VL2 to D15B7 engine?
 

I have a IHI RHB5 VL2 turbo from Fiat Uno 1,3 Turbo and I want to use it to my project - D15B7 Turbo but I don't know is that turbo will be good to my engine. Is that turbo won't be too small?
In Uno 1,3 Turbo it have full boost (0,8 bar) at 3rpm. I want use that turbo at 0,5 bar.
