I just had a quick question. With these 2 pictures can anyone tell me if this is indeed a GTiR manifold?

IM not sure I used to know the difference. yet I do have a gtir manifold and heat should laying around is Someone local wishes to purchase. I have nano other parts id like to get rid of to locals

Why not ship? Parts are relatively small.
Well i was going to buy that one above but the seller wasnt sure if it was GTiR mani (not a turbo guy) i thought it was but wanted to make sure before I pulled the trigger....
yes it is
Just curious, how do you tell the difference? Is it the divider in the outlet flange?
I don't ship because I don't have paypall.
If Pepe sent me a money order they would have to wait to I get it and cashed it till I would ship out

It is not, an avenir manifold has one too and looks nearly identical to the gtir with one distinguishable difference, usually pretty easy to point out. The runners from the top of the manifold on cylinders 1 and 4 have dimples/notches right near and where the manifold mounts to the cylinder head on the w10 and w11 manifold. The gtir is not constricted and appear to be open for better flow, although the avenir has been said to make more power in the lower rpm range with smaller turbos because of its capabilities to help spool faster. The gtir will always flow better for t2 setups because of the larger exhaust runner design.

In the end gtir will typically make more power, that's why they are more sought after.

So you also agree this is a GTiR mani?

Yes, that is a GTiR manifold. It is not an avenir or a bluebird, and the bolt for the heatshield in the front is in the right place.
GTiR will also have a slight inward angle on the hotside flange for the turbo to give the compressor side of the turbo more clearance from the block. That's why the bigger compressor T2 turbos clear better with the GTiR.

Just another thing I wanted to add in there when trying to distinguish the 3 different types of OE FWD T2 manifold castings.
Thanks fellas, bought it for a good price
