Internal Wastegated Turbo Question
 

Ok here is the deal I got my manifold and its VERY nice, but I want to run a external wastegate so I can initially run lower PSI, but the manifold would need to be cut up and a flange added for that. A friend suggested to me to do some research on usign a internally wastegated turbo (a t3/t4) now my question is can I lower the boost on a internally wastegated turbo to something like ~5psi?

Or should I just get this one flanged and run my Tial wastegate plan that i was thinking of using...

Thanks ahead of time.

you can always change the spring on the internal wastegate, like on my 14b i could change the spring to like 5-6psi...do whatever you want pierre

Re:Internal Wastegated Turbo Question
 

you can lower a internally wastegated turbo by extending the actuator arm, but this increases lag. you want less lag especcially with such a bigger turbo than a say T25. but if you want a quick and accurate spool id get a manifold with a external wastegate flange. (you might even be able to keep your ac)

found a soultion, weld it to downpipe...and use a dump tube :)

How would this work? I think you have to have it before turbo don't you.

nope, here i will show ya it worked fine on my buddies DSM w/ a 20G...

Ahh I get it now,never seen one setup like that before 8). Learn something new everyday.

Re:Internal Wastegated Turbo Question
 

is there enough room to do that?

going to a good shop tommorow and talking to some experts to see what is the best option, not the cheapest. Thanks

that's sweet never seen that before

...what the hell... ? It looks like that would only work if the gasses that went to the wastegate were able to bypass the turbine wheel somehow, which would not be possible on a turbo without an internal wastegate housing...

EDIT: I see now that the turbo housing in the picture IS internally wastegated, which confirms this. Your turbo needs to have an internal wastegate housing, even if the actuator arm is missing.
