recently bought a Jdm B16 head and im not shure if its to be concidered as an sir head or a 1st gen GSR ? the casting number is (PR3-1) thanks

 

From what Im told, the casting number are the generations. PR3-1 is first gen so im guessing B16A1. i have also heard that the code is for a OBD reference.

i think its

pr3-1=obd0
pr3-2= obd1
pr3-3= obd3 and so on

 

but is it a GSR or SIR head ?

 

Im thinkin its a Xri GSR head

 

all I know is the date on the block is in early 90's

 

no... its a b16a head. pr3 was the casting numbers for the 1st gen b16 heads. And your head is obd1 or obd0. Chances are obd1

 

1st gen heads were ODB-0, 2nd gens were OBD-1 and so on......

 

Just checked the head on my b16a2 it says PR3-3. and it's OBD2.

I believe the PR3-1 is the b16a head with OBD-0. (not b16a1)

 

Yea your right, I went back to some pics of my OBD0 b16"a" and my casting was PR3-1

So you have an OBD0 B16a head. Came out of the 1988-1991 civic ef9 and the 1990-1991 Integra da9

 

Noone sees these posts? I said the EXACT some thing!!!!!!

But yet, you only see his post? WTF!!!! AHHHHHHHHHHHHHH!!!!

 

^^^^ lmao was waiting till you notice this hahaha.

 

you said GSR :P its not a gsr head. But non the less, I agree with you too then.

 

I meant...XRi/GS-R integra...with the B16 head, oops

 

thats ok, I still love your car... opps I mean you

 

the only way you can make it up to me is.... THE KEG for dinner!!!!!

 

also needed to know if there was a big difference between the p06 ecu and the p28 . thnx guys ur being of great help and hope 2 see some of u tomorrow. if you see a confused white DA you know its me lol , 1st time coming

 

if you see a black da with the whole back end primer, thats me.

both those ecu's are obd1. the only big difference is the p28 is stock for a 1.6 and the p06 is 1.5. the p28 is vtec p06 non vtec.

 

forgot to mention that the p06 is chipped . is it pretty much the same then ?

 

Both will be the same for your use. Both will need to be chipped and have software for whatever motor you will be running [assuming the b16a]

And seems like i came on here slightly too late, i could have told you its b16a obd0....i have the same head in my garage :P

 

yeah im gonna be running a b16a head on a b18b block .ill bring the ecu tonight and get u guys to look at it , make shure it'll be good . the guy I bought it from said it'll work the same as p28 . coming with the eg today ?

 

^LS-VTEC FTW!!!! Building one myself, only with a b16a2 head.

 

YES! Another LS-Vtec build. Post pics of your progress!

And also, for some help

How To Build a "Reliable" LS/Vtec

 

gunna be a 81.5mm lsvtec . only things im missing is GSr timing belt,GSr water pump ,GSr belt tensioner , 660cc fuel injectors , aem fuel rail, aem wideband gauge , flywheel , distributor , adjustible fuel pressure regulator, fuel pressure gauge with the water in it and exhaust system . then where rdy to machine , deck ,assemble , install and tune . can't wait for the finnished results an other month or so .

 

sounds good.
