R33 sticky wastegate

Hey fellas 

im having some issues with my 33 the wastegate has started getting stuck open the past few days but eventually after turning the car off and letting it cool you can hear the wastegate snap shut and the spring ping back I assume this is due to metal expansion from heat 

rb25det stock turbo on 12psi any ideas on how to prevent this or what to replace it with 

cheers

A Kando turbo I used to have developed a sticky gate from heat exposure. The collar that goes between the activation arm and flapper would bind. The first time I removed the turbo and used some wd40 and big pliers and worked it loose until it operated smoothly. The next time I just simply took the actuator arm off sprayed plenty of wd40 and worked it loose again. If I was you I would check the gate for smooth operation with the actuator arm not attached.

      Totally equivalent. Stock often goes from the comp cover because that's where the actuator is also installed and the factory needs 2" of hose to make the connection - and it comes as a pre-assembled unit. They totally have a boost reference from somewhere between the turbo and the throttle(s). Oh, jeez. Just do it in M12 then. We don't actually care that much. I would expect any such AN converter fitting to rely on an o-ring or some other seal onto a flat surface under the flange of the hex**, because bolt threads are no intended to provide a pressure seal. unlike..... pipe threads. **which also requires a suitably flat and smooth surface on the turbo's boss to provide the seal.

      I also used NP   That’s were it’s seems to be the best place to fit it? All schematic shows also that it’s should be referenced from the turbo housing. But idk, I do see high hp cars without any connection or anything to their turbos, so I really don’t know how they connect their things

      I do have loctite 243 and 246 and a few more models. I could drill it now in place and make new threads for m12 and order an4 - m12 coupling and fit that to the turbo. Run a braided hose to the EBC which I could get a an4 to 1/8npt

      So M12 and sealant should be fine?    NPT ” because that’s what I had and what I could get atm.

      Wouldn’t touch par if they gave it to me. You need to ask how much power you’re looking to make and then add about 50% to it because that’s what you’ll end up making  The factory box says no more at about 350kw or so, the upgraded synchro boxes won’t handle much over 500kw for long and at that point you’re looking at an auto or dog engagement manual,  once you’ve gone dog engagement you may as well go sequential, they cost a little bit more but it’s worth it  also while you’re at it you should upgrade the transfer case with 10 friction plates
