Wastegate recommendations?

[Dert]

Well once again(4th time now) my wastegate springs are shot in my TiAL 38mm mvs. Once again in less than 500 miles. So I have now had around 2000 miles on this gate and 4 time the springs were cooked and collapsed and 1 time the diaphragm was also blown apart. I havnt taken it off the car yet to inspect it, but I do know I am most likely done with TiAL gates...well at least this one anyways. There has to be a fault in the gate itself causing springs to get heated up and cook. 38mm too small for set up? Running turbonetics T04E 57 trim @25PSI. I need suggestions on a good gate. I currently have a punishment O2 housing that I bought with the gate so if i can re use I will if not i will buy new and sell that one.

Makes me glad that I am running a TiAl 38mm off the manifold. I've had it on this car for at least 40k miles.

Someone should take a heat reading of exhaust manifold compared to the o2 housing. Looks like it doesn't matter now, but is good info to know

Let us know if this new wg fails too, then we know not to buy your car

If gates keep failing, there is definitely a problem with the car. I would be interested to know if this particular Tial was bad. Have any pictures of the welded spring?

My friend has been running "emusa" 38mm. He's had over 15k miles with no issues.

This is good to hear. I have the EMUSA MVS thats going on my new 20g setup.

TiAL wants me to send the gate back so they can give it to a metalurgist, but since I'm switched to PTE, I dont really want to waste $45 on shipping, $80 for tial to repair it, and another $35 to ship back, especially when its something I'm not going to use. I'm currently using a borrowed Emusa, 650 miles so far, no issues, so we are already doing better than the TiAL.

And Paul, was allready looking into the AWD swap as traction is going to be an issue. The T04E 57 trim wasnt too bad, once I got used to launching it I rarely got spin, its not going to have the same grunt that the 6235r is going to have but I'll manage. I'm planning a forged internal 7 bolt stroker build and am going to look into the awd swap at same time
