what wastegate is this? no markings

[ed1380]

Theres no markings. It came with the car. previous owner doesnt know either. Hopefully it's not a chinese knockoff. inlet is 37mm. outlet is 40.

Definitely a Chinese knockoff of some type. Looks like they were targeting the HKS 40mm design.

it still cant be half bad. right? it's used and it still holds vacuum.


what can you tell me about the bolt patter on the manifold and wastegate?

definitely an ebay china copy. One thing that's consistant i've noticed is the smaller 10mm banjo bolts whrere as real Tials and others seem to run a larger 13 and 14mm banjo. But i've got several like the one in that pic fropm china copies i can show ya if you wanna see a tial one and china one side by side

HOwever. aside from weaker material on the diaphram i've seen many many china/ebay WG's in service around here doing their job just fune so i wouldn't be too scared of it. on the tial copies the springs, diaphrams and all inbterchange so parts can be bought from the real parts manufacturer

I'll take that as good news. the closest it looks like is the tial 46

Looks similar to an ATR wastegate to me?

Meh, the more I look at it, the more I want to say it doesn't look like an ATR. Sorry

Once it's heat cycled, the diaphragm will more than likely disintegrate.

Some knockoff gates I've seen had an orange silicone diaphragm like the authentic models they're copying, and some literally have what appears to be a bicycle tube inside.

I've literally seen XS Power knockoff gates that leaked like crazy brand new right out of the box when given enough air pressure to open them. That's horrible quality control.

 

[ed1380]

yup. i just took it apart and it has a nice orange fiber reinforced gasket.

also did the maths and it's set to 18.5psi
