What Kind of manifold do I have???

[STARION]

hey guys, I got a manifold, and It came off of a JDM, I assumed that it was a 1st gen. But the other day I picked up a small 16G, and looking at the size of the 2 holes thay looked different. so, I took a dial bore gauge to them, and the collector on the manifold is a significantly larger diameter than the hole entering the 16G turbine housing. What kind of mani. is this? why is the collector so large. Is there some kind of special collector ring I need to make this work? (the 2 have DIFFERENT sized steps as well).

How would we know? Pictures? Measurements? Give us the info.

I think it was 60 mm collector volume. Also, if it helps, this mani required no trimming to clear the PS bracket. I just cant figure out why it does'nt match the 16G. If I remember correctly, the collector on the turbine housing was somthing like 43mm.

Ummmm... are you sure you have a 16G?

 

[STARION]

positive.

Oh. Good, I'm glad you are sure. Might want to reevaluate though.

Turbine inlet sizes:

13B (5cm housing)
mounting face: 47mm
inside lip: 39.5mm

14B (6cm housing)
mounting face: 55mm
inside lip: 47mm

16G (7cm housing)
mounting face: 60mm
inside lip: 54mm
