Ok. I basically know how cars (anRX-7's) work. I've only been working on them for a few years, so I'm not really up witht he terms you guys use. I had an 86 626 all last year before it died at 250,000 miles. I went out in December and bought a 7.

"Cats" - I know you're not talking about kitties. What is this short for?

"FC" - Also a term that is thrown around a lot. I have no clue what it means.

If there are any others that you think I might not know, please, feel free to throw them out.

I'm also assuming "N/A" means non-turbo?

Thx

 

cats=catalytic converters
FC=chassis designation for 86-91 (all VIN #'s start with JM1FC3, JM1 just means made in Japan...)
N/A=Naturally aspirated, yes, no turbo involved!



Welcome to the bunch of apples...don't let a few bad ones spoil the image...

 

I was thinking "cats" meant that.

Thx for the welcome.

 

Here are a few more:
ECU = Engine Control Unit. (fires the injectors, pulses the BAC, times the spark & other stuff)
TPS = Throttle Position Sensor. (tells ECU when you should be idling.
BAC = Bypass Air Control. (variable idle air bleed keeps you from stalling)

 

Here's a site you should bookmark.
fc3s.org
Click on "How-To's"
They have tons of good info - including the entire FSM (Factory Service Manuals) - free on-line!

 

Awesome! Thank you!

 

Glossary of RX-7 Terms: http://www.atlantarx7.com/glossary.html

N/A = Normally Aspired (aka All Motor)
No turbo, supercharger, or nitrous.

A couple more good sites:
www.rotaryengineillustrated.com
www.fc3s-pro.com

Here are a few more acronyms you will see around here a lot...
EGR - Exhaust Gas Recirculation
EMS - Engine Management System
FMIC - Front Mount Intercooler
HMIC - Horizontal Mount Intercooler
TB - Throttle Body
ABV - Air Bypass Valve (the stock Blow-off Valve)
MBC - Manual Boost Controller
EBC - Electronic Boost Controller
TT - Turbo Timer

 

Thx! I bookmarked the link.

Also:

S4 and S5?

 

S4 is the early model FC and s5 is the late model

S4 86-88
S5 89-91

there are some japaneese names for these cars to. I think they are Zenki and Kouki ( I probably f-cked that up)

Jarrett

 

S4 = Series 4 (1986-1988)
S5 = Series 5 (1989-1991)
S6 = Series 6 (1993-1995)

 

J-Rat, looks like I double posted at same time as you
You are correct.
S4 = Zenki
S5 = Kouki

 

Rx-7 is NOT like ANY other car on the PLANET.

GO to some of those above mentioned sites first and read up on teh rotary engine

 

To be entirely correct, it means made in Japan by Mazda.
