I bought a 44mm tial wastegate with a 1 bar spring but i need a .7 bar spring. My friend has a 38mm tial wastegate with a .7 bar spring. Can i put a 38mm spring in my 44mm wastegate? Aren't they universal? Just making sure
Thanks,
Dan

 

Looking at the PDF's on Tials website for the springs in the 38mm and 44mm wastegates, it looks like yours has a Large Green + Small Yellow spring, and your friends has a Large Yellow spring. So swapping springs would leave you at 0.6 bar and your friend at 1.15 bar.
