i've got the recirc kit, right now got hyperboost one, want to try out the type s. does this mount on like the hyperboost one? also will be putting on samco turbo inlet pipe at same time. TIA

the Type S goes on with the bottom of the valve facing the pressure tube. Bad thing about the S is that you must set it correctly. If set too soft you can have a idle issue and you will not get full boost. If set too stiff you can get compressor surge which can cause the turbo to fail.

is there someway to know how much to set the valve?

Enough so it doesn't open and not too much that it causes compressor surge.
