Hi all

Is anyone familar with the Borg Warner turbos, specifically the S256 for use on our Lampredi 2L motors?

The S256 is said to be a match for the GT3076R, having a wider efficiency range. My concern is with boost threshold, how will the BW S256 switch on with the .55 hsg? From the reports I have read they wont go anywhere untill well over 4000rpm on the DSM 2L 16V motor. thoughts?
