Difference between TO4B and TO4S???

What is the difference between TO4B(60-1) and TO4S (T4/60-1)???
How many 60-1 turbos are there??
Garrett, Innovative, XS, Turbonetics........etc.
I want to upgrade from my HKS TO4E kit (not the XS kit) 360rwhp and 305rwtq at 15-16 pounds.
I have the HKS cast manifold and just want a little more on the top end.
I have search but I am more confuse now.
V-band discharge???
Q, P, 60 trim???
a/r tangentile housing???
Can you point me to 411 or explain it to me like a 4 year old???

Thanks in advance.

The 60-1 is just the compressor designation. It has a specific inducer and exducer (2.324" and 3.000")

T04S is a designation HKS uses for their specific wheel and housing A/R comination. The S does use the 60-1 compressor. Other companies do the same.

V-band is a special clamping method of attaching the turbine housing to the DP.

Tangentile or on-center is the relationship between the flange and the turbine housing.
