Sooo i plan on a turbo upgrade in the near future on my 12a. I read on here its do-able with the stock nikki carb, you just have to up the system. Bigger jets more fuel flow and all that, but i cant find different jets anywhere online. Any suggestions? Or is it just easier to get my stock jets bored out? Hope somebody knows lol

 

There are many good Nikki threads. The carb can be modded to accept Holley jets and air bleeds. It's a science for sure, and fascinating learning.
The jets and bleeds can also be drilled.

 

I hear that you can walk to California. However, much like a carbureted turbo setup, the only people who do it are either vagrant or looking for a publicity stunt.

"At first glance, the idea of a modern turbocharged engine and carburetors all in the same package appears to be a contradiction. A closer inspection reveals that it is indeed a contradiction." - Corky Bell, "Maximum Boost"

Seriously, you are better off spending your time flipping burgers at minimum wage until you can afford a standalone EMS and throttle body rather than wasting your time and money trying to get any resemblance of performance out of a carbureted turbo. However, I would recommend that you just enjoy your car as-is if you don't want to spend much money on it. I had a blast with my 12A 84 RX-7, and it is the only car that I missed after selling it.

You didn't look very hard.

I'm in SFL, I have a free carburetor for you if you can devise a way to get it.
Needs a lot of rebuilding and cleaning, dusty dusty.

Also doing a project on how to switch from the Nikki Carburetor to a Holley (for more HP) the nikki has way too many fuel lines it's a little rats nest.

here's my carb project, gonna update it soon
