6port 12A manifold needed
Hello all
Does anyone here have a 6port 12A manifold that they want to sell?
i think they came on Jspec 12A's from 1981-85..i think.
Sorry that i had to post this here but its such a rare part that i need most exposure.
Thanks
Jon

Hmm, just speculating here, but perhaps it did peak up to 135HP, but the torque would have been lower than the 6 port 13B. Does that sound right to everyone?

Well, for some unkown reason, all of the jspec engines seem to have more net hp than the usdm ones. I have heard a higher figure on the 12A 6-ports, but I don't recall what it is. Perhaps someone on the European forum would know as they got the 6-ports, along with the Aussies.
I wonder how that engine would perform with an sp on the primarys and secondarys, with a bridge on the aux ports? There's another idea for your experiments Jeff.

If you read here, http://cp_www.tripod.com/rotary/pg18.htm it mostly talks about the 12A turbo. Read closely for the 6 port 12A information. Some of the text appears to be an excerpt from the 'Yamaguchi book'. The carbed 6 port 12A is referenced a few times. Too bad he didn't exerpt the 6 port 12A info as well.

The problem with porting a 6 port 12A is the front and rear plates have oval shaped runners below the round aux runners. The port timing closes at 40° like US-spec 12As, but may not allow much porting beyond that, the manifold is set up in an unknown way (I have not had a chance to look into it), the porting would have to be compatible with the flow capabilities of a Nikki, which having not examined it yet, I have no idea how it's set up.
It's cool to think about, but if I was to build up my friend's 6 port 12A, it would have to retain its 6 port functionality. It would go into a project car that would benefit from these unique features. The length of a 12A with the low end of a 13B, but the high end of a 6 port.
Oh yeah, his manifold is lacking the aux port actuators. I'd hope GSL-SE units would work. Otherwise they'd have to be wired open which would kill the low end and pervert the reasons for taking on the project in the first place.
