I have a 38mm tial wastegate with a 5.80psi spring and my friend gave me a 38mm turbonetics 7.25psi watsegate spring. my question is can i use his spring in my wastegate? i would think as long as both wastegates are 38mm i can do it.

 

Perhaps, perhaps not. Tial springs interchangeable with one another. You may have to try to see if it works with Turbonetics. Most here typically don't interchange companies like that. Give it a shot and see.

 

well i also made another post on if ill need a retune if i only add like 1.5psi? can you tell me if i will need one or not?

 

that's difficult to answer. If you're tuned up to a certain point, anything above it MAY require some additional fuel, but that is determined by your tuner if whether or not he has set the mapping up to stay within an AFR above the point that you had before.

 

ok well thanks i will ask him tomorrow.

To anyone else if you know for sure if the springs are interchangeable please let me know. Thanks

 

i know on my el'cheapo emusa brand wastegate, it says i can use tial or turbonetics springs. haven't installed it yet, so can't tell you for sure. but, springs are so cheap on ebay, why not just get a new one?
