Does anyone know what other spring I could use in a old Cartech wastegate? Called Cartech and they said they no longer make wastegates nor springs, and they couldnt suggest what other springs that would fit. They mentioned that the springs they normally put in their wastegates were 8lbs springs and I am only going to boost 5psi untill I get extra injectors put in. The flange used on the Cartech wastegate is the same as a Tial 38mm wastegate, but I am unsure of the diameter of the Tial wastegate springs to know if it will seat properly. Any suggestions or ideas?

thanx guyz,
Mike

 

just boost to 8psi... meh to 5

 

i think he used rajay...find a rajay dealer and they might help.But then again Rajay may be owned by another big name company now.

 

You can machine a spacer for the lid that holds the spring down. This would take some tension off the spring and lower the set pressure.
