I was driving my DD (maxima) I am also rebuilding a second gen. Anyway in the parking lot I see a first gen and the driver is just getting out so I walk over and start talking to him about 7’s. He does not know much about the car but he started talking about how when he bought it (he is the original owner) how he got the upgraded motor and how it was bigger then the stock motor. As fare as I know all 1st gens came with the 12a. Can anyone tell me more about this “upgraded/bigger motor” He also said something about it only be offered for two years.

thanks

 

he would be talking about the 84 and 85 years the gsl-se models only they came with a 13b and all the extra goodies and better bolt pattern and better suspension

 

I asked if he ment the 13b...he looked at me weird. thanks for clearing that up. I also asked him if he was selling it. he said no.

 

In the US. from 1979 to 1983 all 1gens had 12a's w carburetor.
In 1984 & 85 Mazda introduced 13b's w fuel inj in all GSL-SE models. GS, GSL were all 12A's.

 

yah he might just not of know what engine the shop put in for him sounds like he didnt do the work himslef the guy at the shop probably told him he was putting in the engine from the top of the line first gen rx7 or the gsl-se engine and some people think rotaries have cams and valve and other piston what nots

 

another person forgets about the little guy the"S" hey it comes with nothing but it is the lightest

 

lol

 

Maybe I should think about my 85S next , I have been useing it to steal bits and pieces from. 12A and stick , Hmmmm
