6mm (1/4") is the correct size.


GTR plugs.

I took off and popped open the waste gates again. I redid the clocking of the gate, clean the cap,s off and put on new tape, etc... One of the diaframes looks to have three creases and I would like to replace it. I measured the valve and it came out to 38 mm, I want to make sure that is the correct size so I order the right part. Once again thanks for all the help BP!

Contact Tial, these are MV-S wastegates. They will all have the same internals.

these are all from tial so you know you are getting legit parts, which is a big deal to me.

Well.... I have fixed the problem... by getting two new waste-gates. The waste-gates were pretty beat up. I bought new o' ring's, diaphragms, and new springs, but it still wouldn't seal right. Seems like sitting for 9 months just made them trashed. Either way she is up and running and good to go. I'll post a vid of what they waste gates look like. Is it normal for gate to go after around 4 years?

How were they beat up? The housings were physically trashed? Glad you got it figured out..

gates would stay open, diaphragm was creased, both lips on the waste gate were a little warn down, the o-rings that seal the top part of the gate to the bottom was dried, ETC..

Well the CSF rad's time is up. What is everyone doing for rad's now? Should i go back to OEM or did a good reliable one come out yet?

Go OEM and be done.
