I got a P73 head and was told it was a B16. But im not sure if its a JDM B16B or if its a type R. Is there any really way to tell the difference or tell exactally what it came off of? Thanks Guys


and on this site it says its from a JDM B16B or ITR. here is the link

If there's some green paint near the dizzy it's an R head, if not a B16/17 head.

 

there is no green paint... and can u tell exactally which b series it came off of?

 

On the exhaust manifold side, on the left there are two numbers within a circle. The far left has something like "9|8", this is the year of your head. Report back with what year.

 

first of all


all b16 heads are the same as type R.

buttttttttttttttttt to answer your question.

im pretty sure its a 1991 B16A.
my b16a was a p73. ithink... its been almost a year since i sold that car.

but yes check the year and youll know

 

Honda never made a head with P73 stamped on it. The ITR and CTR used a PR3 casting just like the normal B16A. Here is an old FS thread of mine with pictures and ID for a Type R head. I do not know if the pictures still work.

the dogginator is right..all type R heads are stamped PR3 and GSR are P72. only thing on a block that would say P73 would be the Intake Manifold on an Integra type R motor.
