Alright I have 2 gsr heads.. one is a 93 p73 and the other is a 94 p73.. one of my buddy told me that the 93 one better, but I think there the same.. which one should I use to put on my b18c1 block?? Any advice thanks

 

93 and 94 year model p73s? unless the DA used a different head that i don't know about, i'm pretty sure the p73 is a 97-01 Integra Type-R head.

 

O my bad ppls I put down p73.. I met p72

 

the 92 93 gsr's used the same head as the b16 and type R... if both of your heads say p72 then they are the same the pr3 is the head used on the type r

 

if they are p72's then they are regular gs-r heads and use the GSR style manifold with the IAB's, but i have only seen a b17 head once and i don't recall the manifold on it. Though as far as i know, one is not better than the other. Unless the one from the 94 gs-r had different cams, then there maybe differences.

 

The B17 had the pr3 which has better flow characteristics but the p72 has the quench pads that lower the chances of detination... the p72 has the opportunity for greatness with the time put into it... you can port and polish it and get a skunk2 intake manifold which is basically a ported ITR manifold. I would sell one of those heads and build the other... but if they have the same markings then they are from the same casting and are identical

 

I once heard the b17 motor are suppose to be a little bit stronger than the b18c1??

 

The b17 is just a stroked b16 thats it...

 

who knows, its possible.. there is a guy around here with one in a eg hatch (stock internals) boosting it running 11's - no joke.
