Gemini G series Turbo Manifold

Description

TURBO EXHAUST MANIFOLD – Stainless Steel log style – T25 flange 

The exhaust manifold supplied is a brand new TurboGemini stainless steel log manifold with T25 flange manifold.  (Note: T2, T25, T28, GT2X flanges are all the same stud pattern).

The manifold is designed for an Isuzu G series engine (G161, G180, G200) fitted to a Holden Gemini, models TX-TG, Jackaroo, Rodeo, etc.  This manifold also bolt onto 4Z series engines (4ZC1. 4ZD1, 4ZE1) such as found in Piazza and later model Rodeos as they share the same exhaust manifold stud pattern.

These TurboGemini manifolds have been designed to support over 250hp while still maintaining fast turbo boost response.  They are compact, minimising internal volume, and therefore minimising turbo lag.   Manufactured from laser cut 12mm stainless header and turbo flanges, and using schedule 10 stainless steam pipe fittings, with typical 2.7mm – 3.0mm wall thickness, fully TIG welded and back purged.  These are a very strong, compact manifold, that won’t crack and fatigue after countless heat cycles.

Rectangular or Circular port?

We fabricate our manifolds with a Garrett style T25 flange, that either has the traditional rectangular shape turbine housing entry, such as on most T25, T28, GT25, GTX28, etc turbochargers, or we offer them with a round port to suit turbos such as the Garrett and aftermarket branded GT20 turbos, as supplied in our 220hp turbo kits.   Just select from the drop down above to make sure you get the correct style.
