ok well i was looking in the helms manual for the bolts for the head. i look and the B18c5 head has all the studs for nuts, and the b18c1 head doesnt. just 2 studs for nuts. this is my head it has PR3-4 written on the side. is this a GSR or Type R. dont tell me ever since i been thinking its been a TYPE R. it had the green paint of whatever on that tab too.

whats goin on?

huh? my gsr head has all studs. yours doesn't.

 

i was told it was a ITR... does yours say PR3-4 on the header side?

 

my 2001 gsr has only 2 studs

 

the head is a '00.

 

Phuckin ***.... i swear if this is a GSR head im comin after that damn seller and beatin the living ***** outa him. im really pissed right now.

 

look thought the top of the head, it should be a "30" on it. gsr is 72.

 

ok, im gettin a bit happier, but whats up with the studs.. why is there only two of them. could i use bolts??

 

My Type-R head uses 2 studs and the rest are bolts.

 

hmm what size are the bolts... im sure they are same size as other head bolts.

 

when Honda switched to OBDII from OBDI.. they changed the studs on the head. The older GSR 94-95 used studs and the newer version 96-00 GSR, 98+ Type R, 99-00 Si uses the bolts and 2 studs at the end. The type R/Si head has a stamped P30 on it. If u cant tell from a GSR head and Type R head, then u got problems. they have different combustion chambers and intake manifolds have different bolt patterns so they wont fit if u try to put a GSR on a type R head and the other way around.

 

Calm down, I have only 2 studs as well.

My ITR head says PR3-2 I think (haven't looked in a while).

yea, calm down man. ppl usually take out the stud when they work on porting job.

 

its been 2 studs when i bought it... man that helms manual got me shook.

 

ye u can easily back the studs out or put em in...ive had 2 of em come out on me when breaking them loose...ur ok man u still got a type r head

 

Ok , look at the shape of your combustion chamber, Gsr heads are not round and look like this.

Except this is actually a r head with welded combustion chambers to mock a gsr head.

Take some more pics of the port work though , I would like to see.

ITR head and GSR head is totally different. (What you should be worried is if it is a Civic Si/Del Sol VTEC head)

But since you think it is a GSR head; What Intake Manifold are you using? Where is the Water Outlet Spout located (under the VTEC solenoid or undert the Distributor)? Like mentioned already; How does the combustion chamber look like? Check the Intake Valves.

 

u can relax. PR3-X stands for a B16 head, which is wat type R's use. my type R says PR3-3, but the second # doesn't matter. u have a type R head, don't worry about it.

 

im using the intake mani. from a ITR... it bolts up fine.

 

Even more proof for you , this is my 2000 type r head pr3-4. that should put the nail in the coffin for ya.

 

theres a difference on the combustion chambers from a b18c1 head an a b16a/b18c5 (the b18c1 looks like it has on the chamber to pieces of metal blocking part of the chamber , and thats how a gsr head gives you more CR )

check it out

 

thanx tbone... now im convinced. but my Q is still about the studs, i can get 6-7 from acura carland and put them in, or should i get some bolts that will fit the holes.

 

My head only has 2 studs

 

chill about the head studs...like they said before...they are removable

 

i hear that. when putting in the studs, all they do is screw in. do i need to put some sorta like locking glue or whatever its called on them?
