02 Dump Question..

[EclipseRydazz]

Been used to my 14b with my EvoIII o2 dump housing, boosts great and quick from 1st,
2nd and 3rd. Just seems to me that when I am cruising at say 80 in 5th and throw it into
4th and gun it, I hear the gate open but seems like it doesn't pull like 3rd would, pulls slow.

I just got a Big 16g GT turbo installed, and was wondering if I am better off buying the same o2 housing (EvoIII) but w/o the dump and recirc the wastegate through my exhaust???
I love the o2 dump but, will recircing it through the exhaust cause a chance for boost creep???

Pros and Cons would be great. Thanks

Maybe you have a pre turbo exhaust leak.

Yes you will have a chance of boost creep. You will most likely get creep. But to keep it to a minimum port the turbine housing, o2 housing, and wastegate passage.

have you considered that fourth is never going to feel as quick as third?
