Converting from internal to external waste gate

[project93]

Does anyone know exactly how to go from an internal waste gate to an external waste gate? What parts do i need? do you just weld the old waste gate shut?

Hey brother.

[project93]

hey buddy, how's it going?

[bkmc24]

Sealing the wastegate passage inside the turbo up.
Finding a manifold that has an external WG flange.
Finding an external WG.
Seal and install said parts.
Enjoy.

That kinda what i thought but i wasn't sure. so all i have to do is weld the waste gate shut on the turbo?

Take off the actuator and weld the flapper shut.

What mani do you have?

I converted to external wg on a dsm o2 housing. It required getting an o2 housing that had an atmospheric dump.

Cuttin off said dump.

Removing the internal flapper and external wg actuator.

Fab up a pipe to go to your external wg. Port out the area on the turbo going to the wg.

I had to convert to a civic half radiator as well.

best of luck, this was for a dsm mani and housing.

i was going to do this setup as well but i was informed that the wastegate is supposed to be before the turbo and not after the turbo. any reason someone would be telling me this b/c u don't seem to be having any trouble controlling boost do u

Well, the ports to the turbine and to the standard wg dump spot are essentially the same on a dsm turbo/o2 housing.

Either will work, but putting it before the turbo would work better in theory, but I have 0 issues with controlling boost now.

The air coming out of the motor is going to take the path of least resistance to get out, so if your ports to the wg suck before, or at the turbo, it will suck for controlling boost and it will creep. You also never want to go off of just one cylinder either, you want to divert the air from all 4 cylinders.

I have a DSM Mani with a big 16g turbo. I was kinda thinking I would buy a new mani if i had too however if this method works i like it. lol. could i possibly see a pic of the setup so i understand better?

[chessboxer]

These are about as good as I have

[project93]

ah.

I think that is what i will go with. Thank you.

P.S. I was just looking at you MR thread and your car is amazing. you DID almost the exact same thing i WANTto do.

[chessboxer]

Thanks man! I remember looking at straightedge's turbo setup and thinking, fuck, I want that!

I got close to it I think, but it took a minute.

My setup is hopefully dramatically changing for the better here in a month or so. Cross your fingers kiddos.
