Compound Turbos

[SEvans]

I need help setting up a compound turbo setup for my 1985 Mitsubishi 2. 3 liter Turbo Diesel pickup. The stock turbo is a Mitsubishi TD04. Housing is 4cm2. So what's an appropriate size housing for the second turbo? I need more top end power. Is there a formula that I should follow? Do you have any recommendations on a specific turbo? And Lastly is it okay to remove the wastegates when going to this type of a setup?

I think I remember reading somewhere that turning these up any over stock is just a disaster waiting to happen.

I have had my fuel screw cranked for years without any issues. I know of a endurance racer that uses this engine and he pushes 200hp and 400 ft lbs torque using the stock main, rods, and pistons. He just ported the turbo and head, turned up the fuel screw and added a larger plunger, and then added a custom intake and large intercooler. I just thought compound turbos would be cooler than a ported turbo.
