nsw/act  Turn your GT3076 IW into External gate setup, GT30 rear housing, OEM manifold GFB BOV, Dump pipe etc

Hi guys,

Selling parts of my GT3076 setup that was on my RB25. Basically turns an internally gated GT3076 into external gate, to use with standard intake manifold etc.

This allows much better boost control and allowed mine to make more boost down low, in circumstances where the factory Garret IW wasn't holding shut.


- RB25DET factory cast manifold

- Steel spacer to fit GT30 sized turbo

- Genuine Garrett GT3076 .82 rear housing (5 bolt outlet flange, T3 inlet) with external wastegate flange professionally welded on (to suit Turbosmart HyperGate 45) Internal gate welded shut.

- Dump pipe to suit 5 bolt turbo flange with external gate plumbed back in (including flex join)

- Modified 'J' pipe with relocated AAC pipe & GFB Respons BOV (recirculate or vent to atmo)

- Modified OEM heat shield

- Modified OEM hotside intercooler pipe (to accommodate 2" 90* bend from comp outlet)

- Steel brace (Gibson motorsport inspired) to support turbo and prevent stud flex/warpage


This setup worked really well and I am only selling as I have put a 6boost manifold on.

All you need is a Turbosmart HyperGate 45 and the dump/ wastegate pipe should all line up.


$300 ono for the whole lot.


Located Blacktown, NSW.

PM for more details.
