I have a GT35R and a Tial 42 mm .9 bar wastegate, the wastegate will not close. I have tried every schematic I could find for a MBC, but it still stays open and I have no boost at all. Thanks anyone who can help!

so it is open at idle? Sounds like there is no spring inside of it. Or it is broken

brand new, open at idle and under load , wont go past vacuum

Didn't Johnny have the same problem Billy? Check the diaphram it might be pinched inside??

Could be, Johnnys car was still closed at lower boost. Take the top off of the wastegate and take a look at it.

Here is the issue Ryon is talking about



Everything worked just fine once he adjusted it.

Did you ever open it up when you got it?

Sleeper2G

no i didn't, i was rushing it, i should know better, i will take it off today

Well, the bladder was fine, the v-band is loose though, its closed all the way but still rotates easily. I will try to hook it up to the stock BCS since I am able to reflash again.

Is the fire ring installed? The ring will be installed on the manifold side of the wastegate.

See this diagram - I know it's a 38mm but it still needs the valve seat.
