Hello Honda-Tech!
...I'm in need of EXPERT clarification! I purchased this head a while back under the impression that it is nothing more than an ordinary B16 head... Recently I was told it was an early Type R head and that its very rare..which I highly doubt. Shortly after, I got an opinion elsewhere and was told its a B17 head (early GSR) and was a "better" B16 head and to hang on to it.......
Now I'm very curious but still not convinced its anything special.... I did a little research myself and came to conclusion its an early B16 head and nothing more...

Can someone please clear these assumptions and confirm what head I have?

Thanks in advance!!!

 

Appears to be an early gen b16 head cast in 1989. Fyi, pr3 castings were used for all b16, b17, and type r heads.

 

correct me if im wrong, but the type r heads had slight cleaning on the intake ports from the factory?? my head does not have this......

 

Looks like it's from hmotorsonline U should b able to contact them and find out exactly what it is from the id number on it.

 

R the valves out of the head? If they r take a pic of the tunnel from the under side where the intake valve goes, looking up towards the guide and I can tell u if it's an itr or not.

 

It was made in 1989. Its not an itr head. And how would you know it's from hmotors?

 

Early gen obd0 b16 head

 

I think he's assuming that because one of the head stamps says "HM", assuming that is wrong though unless you mean made by the actual Honda Motors as in Honda itself.

 

Lol 😝😝😂

 

yes that's what I thought. I've had a head before that wasn't stamped so I assumed that was only from hmotors motors. Sorry.

It is NOT a Type-r head due to the casting year. ITR heads (to my knowledge) were only cast beginning in 1995 for 1996 model years.

It is NOT a b17a GSR head either, due to the casting year. B17 casting years only began for the USDM market in 1991 for 1992-1993 model years and b17 engines were not used in the Japanese market.

The stampings indicate cast in (8/9)=1989, month of ( /7)=July for a 1990 model year
OBD-0 B16a.

This "COULD" be from a Japanese spec, Civic SiR, Integra RSi & XSi (DA6-DA8) chassis, as all of these used DOHC Vtec b16a engines.

Regardless of know exactly what type of car it came from, it is a B16a head through and through.

 

B16

You can shine a flash light down a Itr head and see the polished bowls

Plus the 89 is give away it's a old b16

 

awesome thanks for everyones input!

 

I can't believe you had 2 individuals, actually tell you that it could be a itr or gsr head.


With your head, you should identify the cams and see if it has auto or manual cams, or if there even are cams with it?

 

never got cams with it
