So what I have on my hands is a 97' gsr w/ a swapped jdm b18c now my buddy keeps telling me its the b18c(r) and I want to know if you can help fuel the argument haha. I know its a gsr tranny hooked to the b18c block but the head is stamped p-72 which I thought was a gsr head. I haven't pulled the oil pan or valve cover to check yet either haha. Just a picture for you. Let me know what you think.

 

Thats a GSR head, the intake manifold is an immediate giveaway.

 

That's what I thought haha my buddy is a die hard teggy and I can't wait to finally put this argument to an end.

 

A "gsr" no two ways about... but ultimately the pistons tell you however no one puts P73's in and uses a regular stock gsr head.
