Hey 2nd gen people....

I figure you guys (& girls) would know best what these crazy lookin things are that I have been stripping from my FC.

What are the names of these parts?

1.

2.

3.

I'll be posting more as I strip them off. Some things, I basically know what they are....but am wondering if they have a weird name since they are Rx7 parts.

 

1. BAC valve

2.upper plenum

3.crank angle sensor

 

4...

5...

6...

ISn't #3 some sort of distributor? Or is that the correct name?

 

4. middle intake manifold

5. Water pump housing, or something like that

6. Looks like the air control valve, but I havent seen one of those in awhile...

 

What does BAC stand for?

 

bypass air control valve, and yes, that is an ACV

 

Sorry, its the Bypass air control I think. It helps your car idle when extra load is placed on the engine, ie a/c, power steering, electrical load...

 

7...

8...

 

7. A/c mount

8. Throttle body

 

BDoty311 seems to keep winning..

He is correct on all parts.

 

What do I win? And Im not even using my Haynes manual.

 

I have a ton more parts. I'm bound to stump you sooner or later....I'll keep disassembling and taking pics.

 

Throw some hard one's at us those were pretty easy

 

Hah, everytime I attempt to answer the forum pukes. Good job though

 

"Knowing your Basic FC3S Parts - 101"

What are you doing to this FC you are stripping?

 

I was able to pick this FC up pretty cheap. Ever since January when I bought my FB, I have been intrigued..almost to the point of insanity about rotaries.

This FC ran fine...but, since I already have 1, I figured I'd take this one apart, and learn more about them as I go.

While we're waiting for me to post more parts....what are the basic functions or purposes of the items not yet explained?

 

1. Control idle better when there is more load on the engine (electrical).

2. Incorperates the BAC into the intake system as well as other vacuum powered sensors, Air Temp Sensor.. etc..

3. Integral to determining spark

4. Just intake runners essentially

5. Part of the cooling system - Has cooling temp sensor and thermostat mount.

6. Directs air flow from the air pump back into the intake manifold or dump to the exhaust.

7. Just an AC mount and tensioner pulley

8. Makes the car 'go' when you press the 'gas'.

 

Actually, I set that throttle body on the roof of the FC after I pulled the motor. And, it wouldn't start.

 

Why are you trying to start a car with no throttle body? That's a really bad idea no matter how you slice it.

 

Well forget that it has no throttle body, why try to start it with the crank angle sensor and intake manifold removed

 

must be trying to shoot some flames with the car running REAL rich

 

i ran mine with the UIM removed. ran it off starter fluid. lost alot of carbon off that trick. and it sounded bitch. intake was louder than the exsaust.

Some of the replies are slightly off:

#1 is a bac valve off of a 86-88 Non-turbo
#2 is a Dynamic chamber off of a 86-88 Non-turbo
#3 is a Crank Angle Sensor off of a 86-91 FC
#4 is a Upper intake manifold off of a 86-88 Non-Turbo
#5 is a water pump housing off of a 86-88 Non Turbo
#6 is a Air Control valve off of a 86-88 non turbo
#7 is a Air conditioning Compressor mounting bracket off of a 86-91 RX-7
#8 is a Throttle body from a 86-88 RX-7

 

#8 is the Throttle Body from a 86-88 MANUAL, non-california emissions RX-7!! Call the parts right dammit

 

yeah silly me... but my reply was better than it's just a throttle body. At least I got the series right
