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. 1 Link to comment Share on other sites More sharing options...

No reason an internal gate actuator can't have the same. Link to comment Share on other sites More sharing options...

Slowxr6t Member 560 Member For: 5y 11m 25d Location: New zealand Posted 22/04/22 10:31 AM Share Posted 22/04/22 10:31 AM 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. 1 Link to comment Share on other sites More sharing options...

Sounds like 2 of them hanging off the side of ya motor would be a good thing Link to comment Share on other sites More sharing options...
