You my friend are the best at explaining everything in dumb downed way. I’m not super smart with cars but I know what’s going on and I’ve been trying to do a EWG on my WRX but I haven’t been able to really understand how everything works, so thank you so much for dumbing it down for me
The cheap method if you have space for the internal actuator in your engine bay is to just not have the line attached to the actuator. That will keep the wastegate closed so you can run an external.
The waste gate doesn't control the release of boost it reroutes the exhuast gasses away from the turbine allowing the release of pressure to stop it from making boost. A blow off valve will release the excess boost on decell.
Your internal wastegate actuator pushes (not pulls) your wastegate open. It's pushed when the pipe pressure to the actuator exceeds the actuator spring rating (say 20psi) . Doesn't matter as you deleted it but best to be accurate for others who are also learning about this stuff.
Doesn’t the external wastegate add wear on the turbo because it will be spooled also when you are not using boost? internal wastegate would save it from spooling when it doesn’t have to, stressing it less, heating it less, so you can add boost for when you actually need it.
Yes you are correct but in bigger tub or applications where said individual is wanting over a certain power range, it’s actually more recommended and bigger turbos for those applications won’t have a internal wastage at all.
No. It makes no difference. It's just the placement of the gate and freedom of being able to vent to atmosphere. There's other things like tunability but, no, it doesn't change the spooling

You said the rod goes into the diaphragm to open. It does not go in. the boost psi pushes the rod outward to open

Thanks man, was about to weld the flap shut but i’ll give this a go🤟

What did you search on ebay to find that internal wastegate delete
seems like some of the boost control could be achieved by flashing the ECU and telling it to do all this stuff. will try.
Exactly what I wanted perfect thanks I got the same turbo
Is that backpiece really installed without a gasket?
I did that for video purposes but I did install it with a gasket and I do recommend one.
He explains it backwards, when it builds boost, it pushes the rod to slow the spooling, and opens the flap.
I’ve got the same turbo for my nb2 has it held up well? This is just for break in on the rebuild before I go big turbo
held up very well
Basically i just need to change the rear plate? And of course taking off the bracket?
Hey boss where I can get this thing to make my turbo external?
i was able to find what i needed from ebay
do you have a link for that plate with the 3" vband?
and how do you control boost now?
boost controller
Not quite at 2k yet but I subbed :)
thanks!
