Curious of what type of turbo flange so on this 6.5s?? I am wanting to change the turbo out for something with some sound, so alittle large turbo. Thanks for any help.

 

base or exhuast

 

Just the base. I want to use the same exhaust manifold. i can make everything else work. Thanks

 

ill measure it tonight since i got the turbo off. a good turbo would be the A Team Turbo

 

its roughly 4 inch by 2.5 inch. i think its a T3 flange but not sure

 

ok thanks man

The pump has been turned up and has full exhaust and a cold air kit but you cant hear the turbo. The turbo is the factory gm3 and I know its small but was curious if there is a different turbine wheel I can put in or what options I have to make it whine??

 

its a t3

 

no options for a turbine wheel. a good turbo would be an A Team Turbo. it doesnt whine but it decreases backpressure so you get a lot more performance. how much boost are you running with the GM3

 

hmmm i wonder if your having wastegate issues if your not hearing the turbo? my truck is completely stock and i can hear it inside the cab when i hammer on it.

 

i wired the wastegate shut, and it runs up to about 10 psi.
