Does a T3 turbo with internal wastegate mean that you don't need a manifold with wastegate flange? So i wouldn't need a wastegate because it is already present internally?

If the wastegate is internal can i then bolt the blow-off valve to the turbo manifold?

Thanks!

hahaha...and yes you dont need a manifold w/ a external wastegate flange if your turbo got an internal wastegate already....the bov dont bolt on the manifold...it goes on the intercooler piping or on an back door intercooler...

 

just makin sure. thanks!

 

the internal wastegate can be set for different psi correct??

anything from what its set for and up... i.e if its set at 12lb stock then you could only run it 12 lb and up...no less than 12 lb...get it...

 

the bov connects to charge piping before intake throttle body.

Go to the FAQ and study more about turbos before you DIY on your car.

 

Is an internal wastegate better than an external one?

they serve the same purpose but internal gates are smaller and that limits their abilities. if the wastegate is too small it may not allow enough exhaust gas to bypass the turbine, thus creating "boost creep" which means the psi will continue to increase past the set psi of the wastegate spring, this is usually seen in the upper rpms. i think this is why you usually dont see internal gates on the larger turbos, they need bigger external wastegates to control boost consistently.

 

So the internal wastegate can make cause more boost even when unintended? Does this mean that it is not safe and could cause damage? should i just use an external wastegate?

 

its possible but for your setup i doubt you will have problems. most t3 and smaller turbos are internally gated and since you are using a t3 im guessing you arent going for big power or psi goals. you should be fine. there are plenty of dsm guys making big power on internally gated evo 18g turbos.
