No wastegate ? How will you manage boost ? Sounds like you are inviting a head gasket replacement, if not more. I don't think I'd want the BOV to server full time in this capacity.
all the old cummins 6BT that were found on the 1988 to 1993 rams. that had the Holset HC1 turbo were a free float system(no wastegatre or blowoff valve) the boost was proportional to the fuel. the more fuel the more boost. :twisted:
