for my 420a I just bought a t3/t4 turbo, the specs are

.57T Garret Compressor Wheel, .50 A/R Compressor, .63 A/R Turbine, this turbo can easily do 25-30 psi.

3" Inlet Diameter, 2" Outlet, Wet Floating Bearings, 1/8 NPT Oil Inlet, T3 / T4 Footprint

Standard T3 ~ T3/T4 Flange, 5 Hole Exhaust Flange

If anyone knows a place that has a good price on a manifold or if any of you fellow 2gnt'ers have one for sale, let me know. thanks

John
