I just got my jdm type r swap in my 93 delsol done, and the head casting is PR3-1. What head is this from?? It is supost to be a all original 98 j spec type r but the castings say 92-93 gsr (pr3-1) on the head did I get the bone or what?? PLEASE help!! thanks in advance, just about to have a heart attack here!!

 

can you find any marking that sais p73 on the head?
keep in mind a type r head is a b16 head so the pr3 is there on all of them

 

yea b16 and b18c5/ b18c-R have PR3-? on them but i thought that the PR3-1 was early head and the PR3-3 and PR3-4 ere the later models??

 

if i rememebr correctly pr3-3 is a type r head.

 

Hope this helps some I had a problem identifying my b18c from the jdm gsr motor and this sortof helped me. https://honda-tech.com/zerothread?id=888664

 

The block hould have B18C stamped on it. On the head there should be a P30 between the cam on the dist. side.you can see it without removing anything.

my b16 head has pr3-3

 

Thanks for the info guys/gals I feel much better now that I know I didnt get jammed!! and yes it is a real R thank god!!

 

if the motor is already in the car and you have driven it, you can instantly tell if it is a R motor.

 

So it should have a 30 between the dizzy and v-tech solenoid? or it shouldn't?

 

type r says PR3 as well...not p72...but as far as year...yea ide say you were screwed

Yes. All factory Type R head are second gen. B16A Head, but with P&P. Thats why there is a P30 stamped between the cam. So if there isn't then it's probley a first gen B16A head. Then you should check really carefully. In another word you can get a GSR B18C jdm block put a Second Gen. B16A head. red valve cover, and a ITR intake man. and it would look so damn close to type r motor you would have to look very closely to tell the diffrent.
