hello everyone,
I recently bought a 1st gen sa22c 13b powered and it has a nikki carb on it
on further inspection i found the oil and fuel injection holes blocked off.
anyway the first mod i did to the engine was direct fire using t2 coils with very good results. next thing was to fab headers and new exhaust system.
as long as i removed the collector i realized that it was from a 12A so the ports didn't match
i also noticed that there are no diffusers in the exhaust sleeves.
i do believe they used a 12a front cover to mount it along with a front sump oil pan.
so what engine do i have?
last thing is the rare air filter cover that is black and says 6 port induction

 

i think you have an FC engine, with an aftermarket intake, and nikki carb. it has the center bolt on the iron, that is found on the turbo engines only.

the 6 port 12A air cleaners were black, in japan these were 83-85.

the front covers are the same from 74-85, except the GSL-SE has a different metering pump, and the 12A turbo has the new metering pump and turbo drain

 

Lots of giant pictures posted to the forum lately.

 

With forum apps, sometimes i can pix but most of the time, i had to open the browser lol

 

Thank you! I wasn't aware of that center bolt
The only thing that doesn't look like it is from a fc turbo engine is the oil filler neck witch is long and straight like the one found on 12a or 13b na.
Curiosity makes me wana remove the intake manifold and have a look at it as I really doubt someone bought an aftermarket intake to built that engine.

 

the filler neck is just pressed in, so its easy to change

 

I was wondering were did they found the gls-se oil pan since they were never imported here but took a second look at it today and it's a 12A oil pan cut and welded to accommodate the longer 13B :s as long as it does the job I'm fine with it.
