hi everyone,

im trying to get my 81 going... So i bought another 81 car thats been sitting awhile from a friend who lost intrest in the car.... its in bad shape, but the motor runs very strong! As i was pulling the motor out, i noticed that the motor had under the intake, some aux port actuators (2) ... I looks like the ones that are on the 13b engines! but its a 12a! Did they come with those because my 81 that i have dont have those on the intake..i can post some pix if this is odd?? is this normal or am i just seeing things?? would this be a 4 or 6 port or niether??? please help this new person!!

 

does it have a black, or a blue air filter cover

if its black, yet 6 port 12a, i didnt know they even had those in the US



btw PICS??

 

Yeah,

Lots of Pics!

 

Sounds like the 6port 12a from japan.

 

here is a few pix... they are not that good, but try them..
when i got the car it had no air cleaner on it..im not sure if its the same engine that came in the car new or not... i have no history on the car at all..

 

Yep!!

Very Rare..

here is a better pix i posted in the test area...its a little better... man.. pix are hard to post on here..but anyways you all get the idea!! so you think it mite have been imported?.. i wonder if its got anymore HP to it??

 

what would make this engine any diffrent or any better?

 

Torque!

 

what about the carb? was the carb diffrent??

 

Hey not to rain on your parade, but if you decide to go the simple route of not using the 6port design let me know. I would love to get my hands on that intake... I am doing up an SE engine with 12A endplates to make a 4 port 13B and was going to build up the 12A 6port for a truck...

ok ill let you know

 

why did they not bring that to america? thats 2 12a's not in america. turbo and 6 port...

wtf!

 

because you lot got a 13b instead !

the turbo wasn't imported as it wasn't seen to be in keeping with what the american market wanted ... ie. torque. + I'm not sure if it would have met the emmissions standards of the day?

to be fair though they never sold those engines anywhere other than japan so its not like the US lost out ( the GSL-SE can hardly be called losing out LOL )

Plus America and America only got the Rotary Engine PickUp. 13b 4-port and 4.625, it's a 5/8 ton truck!

It's all tradeoffs......

 

geeze I heard that the 12a 6 port was only used for two years, mainly because it sucked so much. Again thats what I've heard, I dont got **** to back it up tho.

Oh yeah, and something else japan didnt get. They didnt ever get a 6 port 13b in a rx-7. There was no gsl-se in japan, and all the FC's in japan were turbo.

 

well i guess there is good and bad on this engine, so should I use this or should i put my other spare engine in my 81..I want to use the one with the most power!

 

itll probly be a bit stronger than a regular stock 12a
maybe 10hp and 10ftlbs or so
