what is the difference between a PR3 JDM B16A head and a PR3 JDM B18C (TYPE-R)head. i have found out so far that the difference between the JDM GSR and TYPE-R are the head stampings GSR having P73 and TYPE-R having PR3 and a green dot near the dizzy. i have a JDM B16A head with PR3 on it and i want to use it on my GSR. but i can get a smokin deal on a JDM TYPE-R head if its any better than the B16. thanks for the help.

 

I believe if you are planning on doing headwork, porting, etc, then the GSR or the Type R head is a better platform. Otherwise the b16 head flows better in stock form. This is what I was told by a solid source. Anyone agree?

 

and the cams but you can always pick up a set of ITR cams and ITR intake manifold

 

going to boost the motor. but in stock form if the b16 is better then why wouldn't it be better modified over say a GSR or type-r head? The b16 head I just rebuilt has a mild port and polish, stainless valves, oem cams for now but i have the opportunity to get a JDM PR3 head for cheep and if is worth it i can rebuild it cheep.
