hi all I have both PR 3-3 and PR 3-4 but I don't know the diference between them.

Any one knows if they are the same or have diferences?

thx

 

My understanding is that there is none. A PR3 becomes a Type R head because of what is done to it after it is cast.

 

The year of the head!!

 

The dash number after the PR3 is the number of the die used to make the head in the manufacturing process. There is no difference.

 

PR3-3 is Type r

 

Some. I had an ITR head with PR3-2.

 

there are like 10000 topics about this

 

actually there aren't

the year of the head is the only clear thing we have been able to tell. pr3-2 was the 96 type r, pr3-3 was 97-? and pr3-4 was the last. since the jdm heads came in unfinished, hand finished and cnc'd as time went on, i've been curious if the casting number in any way dictate which finish you have.

 

this is been discuss before

 

Well then, be helpful and post the links.

 

search reviled this post with a good explanation --> https://honda-tech.com/forums/acura-integra-type-r-8/differences-between-pr3-3-head-pr3-4-head-898679/


BTW, it's so much easier to say "use the search" and do nothing themselves... it was not difficult to find this post but not as easy as it could have been.

 

on that post some people say that PR3-2 its from B16 JDM... I have a friend that owns a Del-sol with a B16A2 he has a PR3-2.

I would like to know if my heads are from ITR.

 

My old FS thread has picture of a stock ITR head.
