T3/T4 needs an external Wastegate
I have a T4/T4 60 trim available to me in great condition for a great price. But, I will need an external wastegate. What would be the best way to run one with the stock exhaust manifold?
Could I get by without one for a while with the factory pop-off valve on the intake manifold set at 8psi?
Could I use the housing with the internal wastegate on the factory turo and rebuild the other using it to have an internal wastegate?
Thanks. I am a little green on turbos with Z cars, and non industrial applications.

nope nope and noooo..... dude, just get a port drilled in in one of your exhaust runners near or on the collector section of your exhaust manifold then have a pipe welded on with a flange for an external waste gate. i recommend using TiAL. its a day job probably not to expensive. and not much down time on the 260. its not your dd is it?

^^^ What he said.
Just get your external wastegate setup. Using the emergency release valve on the intake as your boost regulator would be a nightmare. It flutters like an insane chipmunk & absolutely kills performance (it's acting like a huge hole in your intake mani).

I didn't think I would get lucky to use that. Sounds good theoretically. But, I am sure it does not work well.
Hybridz mentioned something like this too. It's a spacer with a port in it. Welding onto cast iron works like poo most the time.

Even when heating the cast iron to the proper temp while watching with a heat gun, and then welding you can have issues. After a few years of heat cycles you have cracks again, where the stock unit may have lasted a millennium.
I like the idea of the spacer. I might go the route of welding onto the factory manifold if it comes down to it.
