theredone Posted January 20, 2015 Share Posted January 20, 2015 I have recently purchased a tial 54mm wastegate And I'm struggling to find a pressure springs I'm looking for a spring rated at around 0.5 bar I've measure the internal diameter of the bottom v band flange and it's measures 2.125" in metric terms 53.975mm Is this the correct place to measure?

Nic Posted January 20, 2015 Share Posted January 20, 2015 Do the spring guides here help? http://www.tialsport.com/index.php/tech-wastegates Quote Link to comment Share on other sites More sharing options...
theredone Posted January 20, 2015 Author Share Posted January 20, 2015 It's strange because it's as if tial never made a 54mm but that's the measurements my wastegate has Quote Link to comment Share on other sites More sharing options...
pedrosixfour Posted January 20, 2015 Share Posted January 20, 2015 (edited) Is it a new wastegate? If not then perhaps someone increased the bore from 50mm? Or is that even possible?
