Looking for some advice on whats the best way to go to set up twin turbos on a LS engine, LS1 or2 or L98 probably. Will be stock engine, prepared to upgrade cam/springs, probably 10psi max, to go in marathon boat. I know it has been done before and was successful. I am not that up with the injection side of things but it seems to be the way forward. So can I buy a kit to slap onto an engine that contains everything I need with intercoolers, or do I need to make it up? Any advice appreciated.
