subaru 16g turbo

If You have a 2.0 Liter WRX and You are Looking to Make 360 to 400 HP but not lose Spool time. Then a 16g or TDO5H 20g Is a Good Choice.

If You have a 2.5 Subaru STI Engine, Then a Good Choice is to go With a TDO6 or TDO6SL2 20g, with a 7 Blade Billet Wheel, Which Is Good for 425 Hp. (The Shops I build turbos for Told me this is the Best STI turbo Upgrade.)


The Reason Why is Because If the Engine is Larger, the Turbo Needs to Be Larger Or the Engine Will Outflow the Turbo At Higher RPM Causing Loss of Power at Higher RPM.

We Can Build These TurboChargers with a 60mm x 82mm Billet wheel and 58.8mm x 67.2mm Turbine Shaft Also.  However The Purpose of This Post is to Share with You an Excellent Street Turbo.
