I live in VA and i need to pass emissions, but i have a jspec motor...
to have the same emmisions setup as the non jspec motor could i just change the lower and upper manifolds that way i could put on an egr, and other things im missing... that i dont know the names of... like these:

What is the function of each thing im missing?

1. Sposed to be a vacume line here?
2. Dont know
3. This plugs up to the spider vac line for the oil?
4. Whats the thing called that bolts on here for the non jspec motors?
5. sposed to be a nipple here for the thing ^
6. Whats the thing called that bolts on here for the non jspec motors?

never owned a US-spec 13bt so i have no idea haha!

No.

Vacuum port - I think it's one of the ports that does see vacuum.
Stick the FPR to here?


Yes, that's the feed for the OMP vacuum splitter.


It's a air bypass solenoid / valve for...power steering, I think.
It's just for idle control.


Yeah, I think that goes to #4 above.


It's the stupid sub-zero assist valve, and not all US-spec engines have them.
In fact, Mazda recommends to throw that **** away.
Again, it has nothing to do with emissions.

Thanks man, so baisicly i dont need any of that crap? ill just double check my vacume line diagrams for 2, If i were to get just the lower intake manifold with the EGI hole, i could set up the EGR right?

BTW Where in honolulu do you live? i was born there, also might be visiting there for spring break next year!!

RETed

Yeah, none of that is really needed for emissions.

Yes, you can slap on the Zenki intake manifold with the EGR valve, and it should all work.
Just to verify, it is a Zenki 13BT engine, right?

I live in town...right outside of Waikiki.

Why would anybody in his right mind install a EGR on a RX-7? And two goes to the water thermo valve.

lol im not out of my mind is VA Emissions... i hate them with a passion

Where is the water thermo valve?

I don't have my pointer with me, but in the FIRST picture of the back of a similar TB as you have, you can see a light yellow, cylindrical device, just aft and below the thermowax. That light white/yellow plastic device is the water thermo valve. It has two nipples on it. One goes to the small metal nipple you have next to your large nipple for the OMP spider.

In the second jpg, DO NOT pay any attention to the red circles. Look to the far left of the jpg and to the bottom. There appears to the a cap on a cylinder and it's green/grey in the jpg. You see a black hose coming out it's right side and curling up and over the top of the cylinder. The cylinder is the water thermo valve. Same animal as in the jpg above. It's a SIMILAR TB as yours. Only it has four metal nipples coming out the back unlike the two on your TB.

There are pictures in the FSM, FUEL section of the water thermo valve.
