yeah, so for "proper" control of low-ish boost to massive boost window you need a 4-port and external wastegate. Or a 3 port with great control but less of a window of control and even less control with an internal gate. Sounds reasonable to me.

My Landrover distributor has a nipple on either side of the diaphragm. No reason an internal gate actuator can't have the same.

of course the same top/bottom sort of setup could exist in an internally gated scenario.. but it doesn't seem like it's too common haha

Turbosmart make internal gate actuators with dual ports.

I wonder if they fly off the shelves haha

Four port control on an internal gate sounds like a good way to set up a valet tune. 5psi for you and 30psi for me.

Have you guys seen the internal wastegate set up that the borgwarner efr turbos have efr? They have awesome flow to the gate hole. 38mm hole and 42mm wg flapper door. Thinking about changing out the gt3582r for a efr 8474 t3.83 iwg 950hp capable turbo. Would need p steer reservoir relocation and a new 4 inch dump made up. Which I could make myself. They supposedly spool faster than gtx3582r. Look like a mean ball bearing turbo.

 

TurboDirect S.A on YouTube have some really good videos on them.

Have not had a look at the wg hole. Sounds like 2 of them hanging off the side of ya motor would be a good thing

the problem with the borgies is the amount of custom fabrication you need to do to make 'em fit... nobody really does 'em unless they're spending bulk $$ at a specific tuner to get it sorted for them, like @Glouva1 back in the day at nizzy with the twin borgies.

Pulsar are offering medium to large size turbas now.
