Old faithful TO4 unit, P-trim exhaust wheel, H trim compressor wheel, .70 comp cover. Good for near 600 horsepower. Comes standard with 1.32 exhaust A/R .

These units start out life as a TO4E then we throw in a 360 degree thrust bearing, mill out the comp cover and profile it to a T66 comp wheel . Fit and balance the assembly with a T66 wheel making the compressor side able to flow over 750hp. There are cars in Australia running 8.90's over the 1/4 with combo's like this. Comes standard with a 1.32 split pulse exhaust housing and .70 compressor cover. Available with different exhaust housings by request.
