So i bought my gsr teg with this intake mani on and i can't figure out what kind it is. Theres no special drilled holes to fit it on the head. and there is no part number or anything on it. Any help would be much appreciated!

 

You should be posting in the Integra forum.

 

Are you positive it is even a GSR head to begin with?

 

Post the head markings.

 

That's a old skunk 2 or blox manifold

 

thats not even a GSR head, it appears to be a B16. GSR heads have the upper coolant neck at the front of the head, under the vtec solenoid.

 

its stamped p72 on the front

 

Looks alot like a first gen Skunk2 manifold.

 

is there any way to tell?

 

Call Skunk2.
