adam78280z Posted August 13, 2012 Share Posted August 13, 2012 I'm running a GM-4 turbo from a GM diesel. t3/t4 setup. The diesel actuated the wastegate from the vacuum pump and therefor there is no spring in the actuator. I will make a new removable canister end to support the rod and the spring. I'm guessing I'll be somewhere between 15 and 20 psi MS2/EDIS/440cc. I would like MS to control the boost through a boost solenoid but I need to know what base spring rate/pressure I need!
