If it's really a 91 then it's an S5

A picture would solve this from the start.

Fumi

being a 91 NA to start off its just a BASE. they combined GXL and GTUs in 91 to make just a base

There's been a lot of vague and sketchy answers to this guy's questions. Unfortunately, the images of the original Mazda brochures in the FAQ have been down for about a month since they were hosted on Icemark's old site, so referring the OP to the FAQ is not really all that helpful.

First, S4 = 1986-1988, S5 = 1989-1992 (1991 in the U.S.)

In 1991, all non-turbo RX-7s were called "Coupe," not "base." There were various option packages on the Coupe. All had power windows, some had the upgraded 4-piston front brake calipers/vented rear rotors, some had the base brakes.

If the car originally had a turbo engine as the previous owner stated, then this car may have started as a Turbo model, even if now it has a hood without a scoop, which is a pretty easy swap and popular if you switch to a FMIC. If this car was a Turbo from the factory, it would have come with the upgraded brakes and the Turbo-specific seats and interior trim. Also you'd have an LSD. Is there a factory boost gauge in the instrument cluster? These are some things to look for to figure out what the car was originally. (Of course, there were apparently a few highly-optioned non-turbo Coupes that did have an LSD, but that is less common.) Maybe the best way to figure out what it was to start with is to check the tire information decal inside the driver's door. If it specifies 16" wheels, it was originally a Turbo since all NA 1991s had 15" wheels.

Unlike 1986-1990, all 1991s had power windows. Also, all '89-91s had the "split" or Aero mirrors.

As to the "chassis code," I guess you're referring to "FC" which is generally the shorthand by which these cars are known.

Trouble is, at this point nearly everything that originally was on your car may have been changed by a previous owner. Agreed that photos would help us identify the car.

The model it is: Frankenseven
The model it was: Doesn't matter, it is no longer whatever it was.

How is anybody on the internet supposed to know that without any pictures or even a description?

It is on a sticker inside the driver's side door jam.

See the FAQ. If your VIN indicates that it was made in 1991, then it was an S5. However, the S4 and S5 parts are pretty much interchangeable, so your car could have various parts put on it over the last 18 years.

Search the 2Gen forum for threads with "idle" in the title.

See chapter 00 of the 1989-1991 factory service manual and inspect all items in your car's mileage range to see if they need replacement. It would be nice if the previous owner can tell you when everything was replaced.

Aaron Cake's website also lists a buying guide which lists the common problems with these cars:
http://www.aaroncake.net/RX-7/buy1.htm
http://www.aaroncake.net/RX-7/buy2.htm

Things I recommend:
Engine Oil - Castrol GTX (see the manual for the proper weight for the temperature range of your region). Replace the two oil pedestal O-rings about every 50,000 miles (two needed).
http://www.mazdatrix.com/getprice.as...m=10-1601-9954
Oil Filter - The ugly Mazda brand filter is actually very good.
Fumoto Oil Drain Valve F106 without the nipple - Makes changing oil very easy, even without jack stands if you have a low-profile oil pan.
Transmission and Differential Oil - Any type of synthetic. I like Red Line brand, but other brands are fine too.
Engine Coolant - Green ethylene glycol type mixed with distilled water.
Thermostat - Nippon
Spark Plugs - NGK
Brake Fluid - Flush the whole system with ATE Super Blue to make sure you know that it is completely flushed when the bleeding turns from amber to blue. Then next time you can either use Castrol LMA or ATE Type 200 to make sure it is fully flushed when it turns back to amber from blue.

I swapped a complete s5 interior into my s4, so if you were describing my car, no one would be able to accurately tell you JACK.

Check the door sticker and vin. That will get you the farthest.

look at teh brakes, if it is single caliper, than its a NA chassis, unless that was swapped..

Sounds like a Coupe though, mine is also a 91 coupe, but with everything converted.

Seriously...can you find someone who speaks English a little better? If English is your second language, I'm not trying to be rude but people are trying to help you and 99% of what you are saying makes no sense.

stfu and don't post here if his English is bothering you. English is my second language as well and it's not cool when people talk **** especially when you are trying and learning. if you want to help then help if not stfu and go on to the next thread cause you are not f'ing helping

to the original poster, you should consider learning the most you can about these cars first b4 jumping into one.. it may become a headache if you dont know much about them and something happens.

good luck!

need RX7

OP, from the sound of it, your car started out as an S5 n/a (9k tach is a dead giveaway) that someone swapped a TII motor into. Pretty common, but can be a pain if the person who did the swap is a hack.

and JDM motors are a 50/50 gamble...

I'm trying to help but the ability to understand is quite crucial to that. Considering the amount of kids who post threads that sound like this, "yo dawg lik wutz gud for mah 7" you should understand.

I understand your reaction to my post considering your own experience, but if you re-read it, I simply asked if he had someone who could help make what he was asking more understandable.

If I moved to a different country I'd learn the local language...but I live in the US so it would be nice if others took the time to learn English like you did to help communication. That is all. =)

"5 speed" means the transmission, but not necessarily the differential. Most likely he included the turbo LSD, but it is also possible to attach the turbo transmmission to the non-turbo differential with a driveshaft sold by Mazdatrix, or by various ghetto methods.

Agreed. I have a lot of experience working with foreigners, leet-speaking teenagers, and the downtrodden, but the phrase "whats the best 1b that there is ?" still makes no sense to me.

Just so that you know where I am coming from, I will use the original poster's language in my reply...

iT s33m5 2 me that teh o-riginel postR iz poorlie edukated, haz mad sloppy typing skillz, uses l33t 2 much, n doesnt spell check hiz wrok. I dont c wut this has 2 do wit "trying and learning". Mane forn-speeking members on this forum hav gon thru a lot of fert n an attempt 2 communicate. Teh OP... not so much. I think teh OP should try 2 communcait betr, or hav som1 else communcait 4 him, as recommended bi Gringo Grande.

Pictures are worth a thousand words. If the car has been converted and/or repainted it could be difficult to figure out what it once was.

On another note, I agree with the idea that you should probably do more research on this car before you continue. RX7's can me a real headache if you don't know its quirks. Not only that, but if this is your first car I'd be extra careful. There is a lot of helpful people on this forum and a lot of information that can be found form using the search feature.
