will a itr im fit on the b18c1? just bought my car and was told that it has itr im but someone i talk to said that itr im won't wit. it's def not a stock gsr im, cuz it's different from my bro in law's.

 

probably first gen skunk2 manifold.

or a gsr with a b16 head with an itr manifold.

 

ITR manifold will not fit a GSR head.

 

hmmm don't look like the head has ever been pulled off. will have to post pics later or something

 

its probably a BLOX or 1st gen Skunk2

Yup, and as everyone else is saying, Blox or 1st gen Skunk2 manifold. They're modeled after the ITR manifold so maybe that is what he meant..

 

Look for the casting number on the front of the head. P72 = GSR, P73 = ITR.
