Product Description
These are all the optional springs for the AGP 38mm and AGP 46mm External Wastegates. The chart below shows the base spring rates for these springs in either wastegate. Keep in mind that your actual boost will vary depending on your pre-turbine exhaust backpressure. You can combine the Big Green spring with any of the small springs to achieve your desired base spring rate; just add the psi numbers together.
Big Green Small Green and Small Red are no longer available
