Hi I am building up a rb25det. I want 400hp at about 18-20 psi with min lag. It will have

- ACL racs series bearings (main and rod)

- ACL forged pistons

- ACL full gasket kit with MLS head gasket

- Gready forward plenum

- Top mount exturnal wastegate

- Thinking 555cc top feed injectors + fuel rail to suit (not sure if size will be enough for 400hp)

- 3" exhaust

- 600x400x75 fmic

- Computer system ??? (been told the VN comodore computer is vertually the same as a Mo-Tech, could be a cheap option)

- Turbo ?????

I have seen a turbo with specs

- ball bearing

- Turbine Housing: A/R .68

- Turbine Wheel: Trim - 75 Major -2.52" Exducer 2.28"

- Compressor Housing: A/R .70 Inlet 4" outlet 2.5"

- Compressor Wheel: Trim 60-1 Major 3" Inducer 2.36"

- Flange t3 (same as stock turbo)

Can anyone tell me if this turbo will do what I want? Any usfull info/guidence would be appreciated.
